The home stacked energy storage system adopts a stackable design, which is easy to expand. A single battery PACK is 5kWh, which can be combined and expanded as needed, with a maximum capacity of 100kWh. Each PACK is equipped with an independent battery management system (BMS), supporting multiple protections (overcharging, discharging, overcurrent, overheating, short circuit), and always guarding safety. The top can be stacked with reverse control modules for use, and stacking three inverter modules can achieve three-phase electrical output.
