Sail Solar 250kW hybrid solar energy storage system is built for factories and commercial use, with optional 250kWh or 500kWh LiFePO4 battery.

If the grid goes down, it automatically switches to backup mode to keep your critical production equipment running.The full package includes solar panels, hybrid inverter, battery cluster, switchgear and remote monitoring. Available for rooftop or ground mounting, CE/IEC/TUV certified.
