Integrated vertical cabinet design is adopted for floor-standing LiFePO4 batteries. Cells, BMS and terminals are pre-assembled at factory without on-site cell assembly, enabling quick wiring and placement after delivery. No wall damage is needed, and the unit can be moved freely during relocation. Equipped with cloud monitoring module, it supports real-time data check of power level, charge status and fault alerts via mobile APP with remote mode adjustment. Compatible with mainstream PV inverters, it switches freely between on-grid and off-grid modes. The sturdy anti-collision cabinet with neat internal wiring allows single-module disassembly for easy maintenance without full unit teardown. Easy to install for ordinary families, shops and rural houses, it simplifies storage operation and cuts labor installation & repair costs.
