Off-Grid Horizontal Stacked Solar Storage System 3.84–15.36kWh
Horizontal stacked off-grid solar storage system with 3.6kW pure sine wave inverter, MPPT solar charging, 3.84–15.36kWh LiFePO4 battery capacity and flexible backup power for homes, small businesses and remote areas.
The ShanPu off-grid horizontal stacked solar storage system pairs a 3.6kW pure sine wave inverter with 3.84-15.36kWh of LiFePO4 battery modules in one modular stack — a standalone power source for off-grid homes, cabins, farms and sites with unstable grids, with no extra inverter needed. Battery layers can be added on site to grow storage from a 3.84kWh starter system up to 15.36kWh, while the MPPT charger accepts up to 5000W of solar input plus mains charging.
