5kWh Wall-Mounted LiFePO4 Battery 51.2V 100Ah (48V System Energy Storage)
5kWh Wall-Mounted LiFePO4 Battery · 51.2V 100Ah (48V System)
Product Overview
This 51.2V 100Ah (approx. 5.12kWh) wall-mounted LiFePO4 battery is designed for 48V home energy storage systems and works with mainstream hybrid inverters. The slim wall-mount housing saves floor space; the built-in BMS provides over-voltage, under-voltage, over-current, over-temperature and short-circuit protection; multiple units can be paralleled for expansion (pack voltage difference <0.5V). It is the core storage unit for residential PV storage and backup-power scenarios.
Key Features
- LiFePO4 cells: inherently safe chemistry with long cycle life — lighter and more durable than lead-acid;
- Slim wall-mount design: hung on the wall with zero floor space — ideal for garages, utility rooms and balconies;
- Smart BMS with multi-level protection: over-voltage, under-voltage, over-current, over-temperature and short-circuit protection with real-time status monitoring;
- Flexible expansion: parallel connection supported (pack voltage difference <0.5V), series connection also supported — scale capacity as needed;
- Wide operating temperature: charge 0~50℃, discharge -10~60℃ for varied installation environments;
- Natural cooling: fanless and silent, maintenance-free; usable at altitudes below 4000m;
- M8 terminals: M8 copper stud terminals for firm, convenient wiring;
- System synergy: combine with solar panels and a hybrid inverter for a complete home PV-storage system — charge by day, discharge by night, and watch the bill shrink.
