This 250kW commercial & industrial hybrid energy storage system offers 250kWh and 500kWh HV lithium battery options.Paired with solar panels, it stores excess daytime power to cut factory electricity bills and reduce peak demand. It enables seamless switch to backup power during grid outages for critical loads. Core components are pre-assembled before delivery for easy on-site installation and lower initial investment. Widely used in Africa, Latin America, Middle East C&I PV projects. The system can be paralleled to reach MW-level capacity.
Introduction of Inverter & Battery

The Megarevo 250kW hybrid inverter is designed for commercial and industrial solar energy storage systems requiring high power output and reliable energy management. It integrates solar PV, lithium battery storage, and grid interaction into one intelligent platform, supporting both grid-connected and off-grid operation.
With robust power conversion capability, the inverter ensures stable performance under high-load conditions and complex grid environments. Seamless transition between on-grid and off-grid modes enables uninterrupted power supply for critical loads during grid outages.

The system offers 250kWh and 500kWh battery options, engineered for high-capacity commercial and industrial hybrid energy storage applications. The battery system provides stable energy output and high charge/discharge efficiency to support demanding load conditions.
An integrated BMS continuously monitors voltage, temperature, and state of charge, ensuring safe operation and long service life. The modular and scalable design allows easy system expansion and seamless compatibility with hybrid inverters and EMS platforms.

Sail Solar 250kw energy storage system acts as a flexible energy hub that interconnects multiple energy sources and users. It can receive power from the utility grid, rooftop PV and other clean energy like wind power. The system realizes PV charging, power transmission & distribution, and supports multi-scenario applications including user-side power supply, echelon battery utilization and microgrid operation. It realizes bidirectional energy flow, intelligently stores surplus renewable energy and dispatches power as needed, helping commercial and industrial clients optimize electricity consumption, cut energy costs and build stable off-grid or hybrid power supply networks.
