What Is a Solar-Storage-Charging System? A Guide to Integrated Energy Solutions
Understand how solar PV, battery storage and EV charging work together in an integrated energy system.
A solar-storage-charging system integrates solar photovoltaic (PV) generation, battery energy storage and electric vehicle (EV) charging into one coordinated energy system. It uses solar power to supply site loads, stores surplus electricity in batteries and releases stored energy when solar generation is insufficient or charging demand increases.Unlike conventional grid-powered charging stations, this architecture coordinates multiple energy sources and loads through power conversion equipment and an energy management system (EMS). It can help commercial and industrial sites increase solar self-consumption, manage charging peaks and make better use of available grid capacity.
Typical applications include commercial parking facilities, solar carports, fleet depots, factories, logistics centers and public EV charging stations.
What Is a Solar-Storage-Charging System?
A solar-storage-charging system, also known as a PV-storage-charging integrated system, combines three core subsystems:
Solar PV generation: Converts sunlight into electricity to supply EV chargers and other site loads.
Battery energy storage: Stores surplus electricity and discharges it when generation is insufficient or demand increases.
EV charging infrastructure: Delivers electricity to vehicles through compatible AC or DC charging equipment.
These subsystems operate through supporting equipment, including PV inverters, a power conversion system (PCS), a battery management system (BMS), an EMS, electrical distribution equipment and protection devices.
The defining feature is coordinated energy management. Solar generation, battery charging, EV charging and grid power exchange are controlled according to available generation, battery state of charge (SoC), site demand and grid connection limits.
How Is It Different From a Conventional EV Charging Station?
A conventional EV charging station relies primarily on utility electricity. A solar EV charging station adds on-site PV generation, while a solar-storage-charging system also incorporates battery storage to manage differences between solar production and charging demand.
| System Type | Energy Sources | Battery Storage | Main Operating Characteristics |
|---|
| Grid-powered EV charging | Utility grid | Not required | Charging depends primarily on grid electricity |
| Solar EV charging | Solar PV and potentially the grid | Optional | Uses available solar generation for charging |
| Solar-storage-charging | Solar PV, battery and potentially the grid | Integrated | Coordinates generation, storage and charging demand |
Battery storage is not necessary for every solar charging project. Its value depends on the site's charging schedule, PV generation profile, grid capacity and demand management requirements.
How Does a Solar-Storage-Charging System Work?

A typical grid-connected system manages six operating processes. The actual power flow depends on its electrical architecture, available solar generation, battery SoC, charging demand and grid conditions.
1. Solar Power Generation
Commercial solar PV modules generating electricity for an integrated solar-storage-charging system
Solar PV modules convert sunlight into direct current (DC) electricity through the photovoltaic effect. The amount of electricity generated depends on:
Solar irradiance and local weather.
Module orientation and installation angle.
Available rooftop or parking canopy area.
Shading from surrounding structures.
PV capacity and inverter configuration.
In a conventional grid-connected configuration, a PV inverter converts the generated DC electricity into alternating current (AC) for the site's electrical distribution system.
For commercial rooftops and solar carports, high-output modules such as 610–635W N-type solar modules can be considered when planning PV capacity and available installation space.
2. Direct Solar Power Consumption
Available solar generation can supply EV chargers and other connected site loads directly.
When PV generation is lower than total site demand, the utility grid or battery storage can supply the remaining power, depending on the system configuration.
The proportion of solar electricity consumed directly depends on the timing of PV production and site demand. For example, a workplace with daytime EV charging may consume a substantial portion of its solar generation without requiring all surplus electricity to be stored.
3. Surplus Solar Energy Storage
When PV generation exceeds immediate site demand, a battery energy storage system (BESS) can store the surplus electricity for later use.
The charging pathway depends on the system architecture:
AC-coupled system: PV electricity passes through a PV inverter before reaching the AC distribution system. A bidirectional PCS or storage inverter then converts AC electricity into DC to charge the battery.
DC-coupled system: PV generation and battery storage share a compatible DC-side power path. A DC-to-DC converter manages power transfer between the PV array and battery, while compatible inverter equipment connects the system to the AC network.
Stored energy can later support EV charging when solar production declines or demand increases. This is known as energy shifting, which transfers available electricity from one period to another.
4. Battery Discharge for EV Charging
When EV charging demand exceeds the available solar generation and permitted grid supply, the BESS can discharge to provide additional power.
This is particularly useful when several vehicles charge simultaneously or when a fleet depot experiences concentrated charging demand after vehicles return.
For example, a depot with a limited grid import allowance can use battery discharge to supplement grid power during overlapping charging sessions.
This function is called power buffering. Unlike energy shifting, which focuses on transferring electricity across time, power buffering supplies additional power during periods of high demand.
Two battery parameters determine its effectiveness:
Power capacity (kW): Determines how much power the battery and its conversion equipment can deliver at a given time.
Energy capacity (kWh): Determines how much usable energy is available to sustain that output.
A battery may have sufficient energy capacity but insufficient PCS output to support a high-power charging peak. Conversely, a high-power system may not sustain the required output for long if its usable energy capacity is limited.
5. Grid Power Supplement and Interaction
The utility grid supplies electricity when PV generation and available battery discharge cannot meet site demand.
Depending on the storage architecture, inverter configuration and control settings, the grid may also charge the battery during lower-cost periods. This capability must be verified for the selected equipment rather than assumed to be available in every AC-coupled or DC-coupled system.
Where interconnection agreements and local regulations permit, surplus PV generation can also be exported to the grid.
Some systems support backup or islanded operation during grid outages. This requires compatible grid-forming equipment, electrical isolation, protection coordination and appropriate control logic.
A conventional grid-following inverter generally cannot independently maintain an isolated power network during an outage. Continued EV charging in islanded mode also depends on available PV generation, battery energy, PCS output and charging load priorities.
6. Energy Management and Power Coordination
An EMS coordinates solar generation, battery operation, EV charging and grid interaction according to system priorities.
It can monitor:
PV generation and available solar power.
Battery SoC and charging or discharging status.
EV charging demand.
Building and facility electricity consumption.
Grid import and export.
Configured power limits and operating schedules.
Based on this information, the EMS can prioritize direct solar consumption, maintain a defined grid import limit, allocate charging power among vehicles or reserve battery capacity for backup.
For example, a system may use daytime solar generation for facility loads and EV charging, store surplus electricity in the battery and discharge it when several chargers operate simultaneously.
The EMS coordinates system-level energy flows, while the BMS monitors and protects the battery and the PCS executes power conversion.
Understanding Power Flow at the Grid Connection Point
The Point of Common Coupling (PCC) is the electrical connection point between the site's energy system and the utility network. Monitoring power at this point helps the EMS manage grid imports, permitted exports, battery operation and charging demand.
A simplified power balance is:
Grid Import = Site Demand + Battery Charging Power − Solar Generation − Battery Discharge Power
Site Demand includes EV charging and other connected facility loads.
Consider a site with the following operating conditions:
Grid Import = 180 + 0 − 60 − 30 = 90 kW
The site imports approximately 90 kW from the grid under these simplified conditions.
A negative result indicates potential surplus power for export, subject to the interconnection agreement and configured export limits. This simplified calculation excludes conversion losses, auxiliary consumption and other generation sources.
What Are the Main Components of a Solar-Storage-Charging System?
Main components of a solar-storage-charging system including PV inverter, BESS, PCS and EV charger
The system requires equipment for power generation, storage, conversion, vehicle charging, protection and control. These functions may be integrated into combined products or distributed across separate devices.
Solar PV Modules and Inverters
Solar PV modules provide the system's renewable energy input. They can be installed on commercial rooftops, parking canopies and other suitable structures.
PV inverters convert DC electricity from the modules into AC power for the site's electrical distribution system in conventional grid-connected configurations.
Some systems use hybrid inverters that combine PV and battery conversion functions. Whether integrated or separate equipment is appropriate depends on the system architecture, power ratings and equipment compatibility.
Battery Energy Storage System (BESS)
A BESS stores electricity and makes it available when required. Depending on its configuration, it may include:
Battery cells, modules and racks.
Battery management system.
Power conversion equipment.
Thermal management.
Electrical protection and safety equipment.
Power conversion equipment may be integrated into the BESS or installed separately.
For EV charging applications, battery power and energy capacity must both match the intended operating requirements. Usable energy is also affected by the permitted SoC range, conversion losses, temperature and battery operating limits.
For commercial and industrial applications, a C&I energy storage system provides an integrated storage option for projects that need to coordinate battery power, energy capacity and site electricity demand.
Power Conversion System (PCS)
A PCS manages bidirectional power conversion between the battery and the electrical system in applicable storage architectures.
Its main functions include:
Converting AC power into DC power for battery charging.
Converting battery DC power into AC power for site loads.
Controlling charging and discharging power.
Executing power transfer according to system requirements.
A PCS differs from a conventional PV inverter in its role and operating requirements. Some systems integrate these functions into a hybrid inverter or combined power conversion unit, so a separate PCS is not required in every configuration.
EV Charging Infrastructure
EV charging equipment delivers electricity to vehicles through AC or DC charging.
AC EV Chargers
AC chargers supply alternating current to the vehicle. The vehicle's onboard charger converts it into DC electricity for battery storage.
They are commonly used at workplaces, hotels, residential facilities and other locations where vehicles remain parked for longer periods.
DC EV Chargers
DC chargers convert incoming power into DC electricity before supplying the vehicle's battery. They are commonly used at public charging stations, highway service areas and fleet depots where higher charging power or shorter charging periods may be required.
The appropriate charging type depends on vehicle compatibility, parking duration, charging demand and available electrical capacity.
An important distinction is that DC charging does not automatically mean a DC-coupled energy system. A DC fast charger can receive power from an AC distribution network and convert it internally before delivering DC electricity to the vehicle.
AC/DC charging describes the electricity delivered to the vehicle, while AC/DC coupling describes how PV generation, battery storage and conversion equipment connect within the energy system.
For commercial sites and fleet operations, a 60–160kW DC fast charger offers a charging option for applications requiring higher power than conventional AC charging.
Battery Management System (BMS) and Energy Management System (EMS)
The BMS and EMS have different responsibilities.
| System | Main Responsibility |
|---|
| BMS | Battery monitoring, protection and battery-level control |
| EMS | Energy scheduling, power coordination and system-level monitoring |
The BMS monitors battery voltage, temperature and current, and manages battery protection and operating limits.
The EMS coordinates PV generation, battery operation, EV charging demand and grid interaction. It uses information from connected equipment to manage energy according to site priorities.
Grid Connection and Electrical Distribution
The electrical distribution layer connects the PV system, BESS, EV chargers, facility loads and utility grid.
Depending on project requirements, it may include:
Transformers and switchgear.
Distribution panels and protection devices.
Electrical meters and PCC monitoring.
Contactors, cables and communication interfaces.
Transformer capacity, protection coordination, metering location and grid connection limits must be evaluated during system design.
AC-Coupled vs. DC-Coupled Solar-Storage-Charging Systems
AC-coupled and DC-coupled architectures describe how PV generation and battery storage connect within an integrated energy system. Their suitability depends on existing infrastructure, conversion pathways and equipment compatibility.
How AC-Coupled Systems Work
In an AC-coupled architecture, the PV system and battery storage connect to the site's AC electrical distribution system through their respective conversion equipment.
A typical arrangement follows this path:
PV modules generate DC electricity.
A PV inverter converts it into AC power.
The AC distribution system supplies EV chargers and other loads.
A bidirectional PCS connects the battery to the AC system.
The battery charges or discharges according to the operating strategy.
AC coupling is often suitable for retrofitting storage into an existing solar installation because a compatible battery system can be added without necessarily replacing the original PV inverter.
However, charging the battery from PV generation may involve additional conversion stages. The complete power pathway should be evaluated when comparing system efficiency.
How DC-Coupled Systems Work
In a DC-coupled architecture, the PV array and battery storage share a compatible DC-side power path through coordinated conversion equipment.
A DC-to-DC converter can manage power transfer between PV generation and battery storage, while a shared inverter or compatible conversion arrangement connects the DC system to the site's AC distribution network.
This configuration can allow surplus solar electricity to charge the battery without first passing through a complete DC-to-AC conversion pathway.
When stored energy is required by AC-connected site loads or EV chargers, the system converts battery DC electricity into AC through the appropriate inverter or PCS.
DC coupling may reduce certain conversion stages, but actual efficiency depends on the complete power path, equipment performance and operating conditions.
Grid charging is architecture-dependent. Some configurations support battery charging from the AC grid through bidirectional conversion equipment, while others have different restrictions. DC voltage compatibility, converter ratings, protection and control settings must be verified during system design.
Key Differences Between AC-Coupled and DC-Coupled Systems
| Comparison Factor | AC-Coupled | DC-Coupled |
|---|
| Electrical connection | Shared AC distribution | Compatible DC-side connection |
| PV connection | Through PV inverter | Through compatible DC conversion equipment |
| Battery connection | Bidirectional PCS or storage inverter | DC-side power conversion |
| Retrofit flexibility | Often suitable for existing AC infrastructure | Depends on existing equipment compatibility |
| Conversion pathway | May involve additional conversion stages | Can provide a more direct DC energy path |
| Grid charging | Depends on PCS and control configuration | Depends on DC-side and bidirectional conversion design |
| Main design considerations | AC distribution and inverter coordination | DC voltage, converter interfaces and protection |
Neither architecture is universally better. AC coupling may be more practical for certain retrofit projects, while DC coupling may suit purpose-designed systems with compatible equipment.
The selection should account for existing infrastructure, battery charging requirements, conversion efficiency, installation costs and future expansion plans.
What Are the Benefits of a Solar-Storage-Charging System?
The benefits of an integrated system depend on how well solar generation, battery storage and EV charging demand are coordinated.
Increase Solar Energy Self-Consumption
Solar generation and EV charging demand do not always occur at the same time.
A battery can store surplus electricity generated during periods of high solar production and release it later when charging demand increases. This can increase the proportion of locally generated solar electricity consumed on-site.
The improvement depends on available surplus generation, battery capacity, charging schedules and other facility loads.
Reduce Peak Demand Through Battery Storage
Simultaneous EV charging can create short-duration demand peaks, particularly at fleet depots and public charging stations.
A coordinated BESS can discharge during these periods to supplement grid supply. Combined with EV charging load management, battery dispatch can help keep grid import within a configured limit.
This strategy is known as peak shaving. Its effectiveness depends on battery power, usable energy, PCS ratings and the duration of the demand peak.
Whether peak shaving reduces electricity costs also depends on the local demand charge structure and the utility's billing interval.
Support Sites With Limited Grid Capacity
Commercial properties may have limited transformer capacity or face delays and costs associated with utility connection upgrades.
Battery-buffered charging can supplement the available grid supply during periods of high demand.
For example, if several EV chargers operate simultaneously and their combined demand exceeds the site's preferred grid import limit, the battery can provide the difference within its rated discharge capability.
However, storage does not increase the site's contracted grid capacity or provide unlimited additional energy. Its effectiveness depends on available stored energy, discharge power and the time available for recharging.
Improve Energy Scheduling and Load Shifting
An EMS can coordinate battery charging and discharging according to solar generation, electricity prices and site demand.
For example, a commercial facility may charge its battery using surplus daytime solar generation or lower-cost grid electricity, then discharge it during higher-demand or higher-price periods.
Three related operating strategies should be distinguished:
Energy shifting: Moves available electricity from one period to another through battery storage.
Load shifting: Changes the timing of electricity consumption, such as scheduling EV charging outside peak demand periods.
Peak shaving: Reduces the maximum grid demand during selected periods.
The financial outcome depends on tariff structures, conversion losses, battery cycling costs, maintenance and the site's actual load profile.
Coordinate Multiple Energy Sources and Loads
An integrated EMS provides a common control framework for PV generation, battery storage, EV charging and grid electricity.
By monitoring these resources together, operators can manage charging priorities, grid import limits, battery operating conditions and energy schedules.
This coordination is particularly relevant to sites with multiple chargers, variable vehicle arrival times and competing facility loads.
Where Are Solar-Storage-Charging Systems Used?
Different applications have different charging schedules, power requirements and grid constraints. These operating characteristics should guide system configuration.
Commercial Parking Lots and Solar Carports
Solar carports install PV modules above parking spaces, combining electricity generation with vehicle shade and weather protection.
When battery storage and EV chargers are added, the parking facility can use the same area for solar generation, energy storage and vehicle charging.
Typical applications include:
Shopping centers and retail parking facilities.
Office buildings and corporate campuses.
Hotels and hospitality properties.
Public and commercial parking areas.
Key design variables include available parking space, solar exposure, vehicle dwell time and daytime charging demand.
Structural arrangements may include single-slope and double-slope designs. Module selection, support structures, drainage and waterproofing must also be considered during project planning.
Fleet Charging Depots
Fleet depots often have predictable vehicle schedules, making charging demand easier to assess than at many public charging stations.
Buses, delivery vehicles and commercial fleets may return to a central facility within a relatively short period and require charging before their next operating cycle.
System configuration should account for:
Number of vehicles.
Energy required per vehicle.
Arrival and departure schedules.
Simultaneous charging demand.
Available charging duration.
Required charging power.
For example, a depot with evening vehicle returns may store surplus daytime solar generation for later charging. If many vehicles return simultaneously, battery discharge power and managed charging become important design considerations.
Factories and Industrial Facilities
Factories and industrial facilities may have substantial rooftop areas, existing electrical infrastructure and regular energy consumption patterns.
Integrating PV generation, battery storage and EV charging can support facility loads, company vehicle charging and demand management.
The existing industrial load profile and transformer capacity should be evaluated before selecting the system architecture.
A factory with stable daytime electricity consumption may use much of its solar generation directly. A facility with additional EV charging demand may require storage to shift surplus energy or support simultaneous charging loads.
For larger industrial energy applications, a containerized liquid-cooled BESS can be considered as part of an integrated storage architecture with battery management and energy management functions.
Public EV Charging Stations
Public charging stations experience fluctuating demand according to vehicle arrivals, charging duration and the number of active charging points.
At sites with limited grid capacity, battery storage can provide short-term power support when multiple charging sessions overlap.
A combination of AC and DC chargers may be appropriate depending on vehicle types, charging requirements and parking duration.
Storage sizing should consider both the required charging power and the energy needed to support repeated charging events. A high-power PCS alone cannot guarantee sustained charging support if usable battery energy is insufficient.
Highway Service Areas and Logistics Centers
Highway service areas typically have shorter vehicle dwell times and higher charging power requirements than workplace parking facilities.
Solar carports can use available parking areas for PV generation, while battery storage can supplement grid power during periods of high charging demand.
Logistics centers may have more predictable operating schedules, but their requirements depend on vehicle types, arrival patterns, energy consumption and turnaround times.
Where shorter vehicle dwell times and higher charging power are required, a 180–480kW ultra-fast DC charging station may be relevant to public charging and fleet infrastructure planning.
What Factors Affect Solar-Storage-Charging System Configuration?
System sizing should start with the site's energy requirements rather than selecting the largest available PV array, battery or charger.
The main variables are solar generation, EV charging demand, battery power and energy capacity, grid connection limits and operating schedules.
Solar Generation Capacity
PV capacity should reflect available installation area and expected solar production.
Important considerations include:
Local solar irradiance.
Roof or parking canopy area.
Module orientation and shading.
Seasonal generation variations.
Existing site electricity consumption.
Expected surplus solar generation.
Annual energy production alone is insufficient for determining system suitability. Hourly or appropriately detailed PV generation and load profiles help identify when solar power is available and whether it aligns with EV charging demand.
EV Charging Power and Demand
Charging infrastructure should match the number of vehicles, their energy requirements and the time available for charging.
Key variables include:
Number of charging points.
AC or DC charging requirements.
Vehicle battery and charging limits.
Arrival and departure schedules.
Simultaneous charging demand.
Daily charging energy.
The total nameplate power of installed chargers does not necessarily equal the site's actual peak demand. Charging schedules and power-sharing controls can reduce simultaneous demand.
For fleet depots, departure deadlines and the energy required for the next operating cycle are particularly important. For public charging stations, concurrent charging demand and vehicle turnover have a greater influence on configuration.
Battery Power and Energy Capacity
Battery selection requires separate consideration of power and energy.
| Parameter | Unit | What It Determines |
|---|
| Battery power | kW | Power available at a given time |
| Battery energy capacity | kWh | Total rated energy storage |
| Usable energy | kWh | Energy available within the permitted operating range |
| Discharge duration | Hours | How long the battery can support a given power demand |
Consider a simplified example.
If a battery system needs to provide 50 kW of additional power to support EV charging for two hours, the required energy delivered to the load is:
Energy = Power × Time
Energy = 50 kW × 2 hours = 100 kWh
This is the ideal energy requirement at the load side, not the final battery nameplate capacity.
If the PCS supplies 50 kW of AC output to the charging load, the battery must provide additional DC-side energy to account for conversion losses. Actual sizing must also consider usable SoC range, discharge efficiency, auxiliary consumption and reserve requirements.
The PCS must be rated to provide the required output power throughout the intended operating period. Sufficient battery energy cannot compensate for inadequate PCS output, while sufficient PCS power cannot compensate for insufficient usable energy.
Grid Connection and Transformer Capacity
The existing grid connection determines how much electricity a site can import and, where permitted, export.
A project assessment should consider:
Permitted grid import and export limits.
Existing transformer capacity.
Building and industrial loads.
EV charging demand.
Available electrical distribution capacity.
Local grid interconnection requirements.
These factors help determine whether storage can supplement short-duration power demand or whether additional electrical infrastructure is necessary.
Battery storage can manage selected demand peaks, but it cannot replace a complete assessment of transformer capacity and grid connection requirements.
Load Profile and Electricity Tariffs
The site's load profile shows when electricity is consumed and how demand changes throughout the day.
Electricity tariffs influence whether battery charging, discharging and load shifting can produce financial value.
A practical assessment should compare:
Solar generation by time period.
EV charging demand.
Existing facility electricity consumption.
Grid import limits.
Peak and off-peak electricity prices.
Battery charging and discharging opportunities.
The economic outcome depends on tariff structures, battery efficiency, cycling costs, maintenance and equipment investment.
EMS and System Compatibility
An integrated system requires compatible communication and control between its components.
Before selecting equipment, project planners should confirm:
Communication interfaces and supported protocols.
Compatibility between PV inverters and storage equipment.
BMS and EMS communication.
EV charger load management capabilities.
Metering and monitoring requirements.
Battery dispatch and charging priorities.
System expansion requirements.
The EMS should also have defined fallback behavior if communications fail or equipment reaches its operating limits. Compatibility must be assessed across the complete system rather than assumed from individual product specifications.
Frequently Asked Questions
What Is the Difference Between a Solar EV Charging System and a Solar-Storage-Charging System?
A solar EV charging system uses photovoltaic generation to supply EV charging demand. A solar-storage-charging system also integrates battery storage to retain surplus energy and release it when required. The additional storage layer helps address differences between solar production and vehicle charging schedules.
Can Solar Panels Charge EVs Without Battery Storage?
Yes. Solar panels can supply electricity to compatible EV charging equipment without a battery. When solar generation is insufficient, the site can draw additional electricity from the grid if a grid connection is available. Battery storage is useful when the project needs energy shifting or short-duration power support.
Can a Solar-Storage-Charging System Work at Night?
Yes, if sufficient energy is available from battery storage or the utility grid. Batteries can store electricity generated during the day and release it later. Available charging power and duration depend on usable battery energy, discharge power, system losses and the remaining SoC.
Can a Solar-Storage-Charging System Operate During a Grid Outage?
Not automatically. Continued operation requires equipment and controls designed for islanded operation, including compatible grid-forming inverters or PCS, electrical isolation, protection coordination and appropriate load management. A standard grid-connected installation should not be assumed to provide backup charging.
Is AC Coupling or DC Coupling Better for EV Charging?
Neither is universally better. AC coupling can be suitable for retrofitting battery storage into existing solar installations, while DC coupling may offer a more direct power path in compatible purpose-designed systems. Equipment compatibility, conversion efficiency, installation requirements and project objectives determine the appropriate architecture.
Does Every EV Charging Station Need Battery Storage?
No. If the grid connection can meet charging demand and vehicles can charge within their available parking periods, solar generation with managed charging may be sufficient. Battery storage is more relevant when a site needs energy shifting, peak demand management or additional short-term power support.
Can EVs Send Electricity Back to the Grid?
Some electric vehicles support bidirectional charging, including vehicle-to-grid (V2G) and vehicle-to-building (V2B) applications. These functions require compatible vehicles, bidirectional charging equipment, suitable control systems and applicable grid interconnection arrangements. Conventional EV charging equipment does not automatically support reverse power flow.
Bringing Solar, Storage and EV Charging Together
A solar-storage-charging system coordinates PV generation, battery storage and EV charging through shared power conversion and energy management. Its configuration should reflect the site's generation profile, charging schedule, battery requirements and grid connection limits.
For commercial and industrial projects, these factors determine whether storage is needed, which coupling architecture is appropriate and how much charging demand can be supported.
