A solar storage charging system is an integrated energy solution that combines photovoltaic (PV) power generation, battery energy storage, and electric vehicle (EV) charging. This system stores solar energy during the day and supplies power for charging or other electrical loads when needed. It enables real-time energy management, maximizes solar utilization, and reduces grid dependency.

Dagong ESS offers modular and scalable integrated solutions, including 100kWh Air-Cooled ESS, 215kWh Liquid-Cooled ESS, and 5MWh Containerized Systems, which are widely used in commercial and public charging facilities.

Types of Solar Storage Charging Systems

There are mainly three types of integration based on system capacity and application:

• Residential Integrated Systems (5–30kWh) – Compact and modular systems designed for homes or small charging points.

• Commercial and Industrial Systems (100–372kWh) – Air-cooled or liquid-cooled ESS units supporting multiple charging piles and PV arrays.

• Containerized Large-Scale Systems (3MWh–5MWh) – Suitable for EV charging parks and renewable microgrids.

For example, Dagong ESS's 372kWh Liquid-Cooled ESS provides stable thermal management and long service life, while the 5MWh Air-Cooled Container ESS supports intelligent energy dispatch and remote monitoring.

Features of Integrated PV and ESS Charging Systems

• High Energy Efficiency: Smart BMS and EMS optimize power flow between PV, battery, and chargers.

• Modular Scalability: Systems can be expanded from small-scale to multi-MWh setups.

• Long Lifespan: LFP cells provide over 8000 cycles and 15+ years of stable performance.

• Safety and Reliability: Advanced fire protection, IP54 protection grade, and real-time monitoring.

• Intelligent Operation: Cloud-based control supports energy scheduling, demand response, and cost optimization.

Applications of Solar Storage Charging Systems

These systems are widely applied in:

• Highway EV charging stations – enabling charging even during grid peaks.

• Commercial complexes and parking lots – reducing energy costs with solar and storage synergy.

• Industrial zones and microgrids – providing stable backup and grid support.

Dagong ESS solutions like 215kWh Liquid-Cooled and 5MWh Container ESS are already powering integrated EV charging projects worldwide.

Price of Solar Storage Charging Systems

The price of solar storage charging systems varies depending on capacity, configuration, and cooling technology. Generally, larger liquid-cooled systems have higher initial costs but lower long-term operating expenses. For specific pricing, it is recommended to contact suppliers for customized solutions.

How to Select the Right System for Your Project?

Consider these factors:

• Required energy capacity and charging demand

• PV array size and site conditions

• Cooling type (air-cooled or liquid-cooled)

• Budget and long-term ROI

Dagong ESS provides tailored system design and technical consultation to ensure the best project fit.

How Long Does the System Last?

With LFP battery chemistry and advanced thermal management, Dagong ESS systems offer more than 8000 cycles and up to 15 years of service life. Routine maintenance ensures reliable long-term performance.
