Description
W15-5A Foot Pad is the floor-standing configuration of Lithium Valley’s W15-5A Residential LFP Battery Series, delivering up to 280Ah and 14.336kWh of nominal energy storage at a 51.2V system voltage. Built on Lithium Iron Phosphate (LiFePO4) chemistry — the chemistry most homeowners are steered toward for stationary storage because of its tolerance for repeated daily cycling — this floor-mounted variant uses a stable foot pad base instead of wall brackets, making it a practical fit for utility rooms, garages, or dedicated plant spaces where floor installation is preferred over wall mounting.
Since this is a 51.2V-class battery, it belongs in the same conversation as hybrid inverters and off-grid or grid-tied backup systems already designed around low-voltage battery banks. Before pairing it with any inverter, it’s worth confirming voltage range compatibility, LiFePO4 charge profile support, current limits, and CAN/RS485 communication protocol alignment — the W15-5A Foot Pad includes integrated BMS monitoring, but that doesn’t replace a proper inverter compatibility check.
Rated for 6,000+ cycles at 80% depth of discharge and IP54-protected for indoor installation, the W15-5A Foot Pad is engineered as a genuine long-term energy investment (10–15 years) rather than a quick-fix backup box. An integrated LED display shows real-time state of charge and battery status, while quick plug-in +/- terminals simplify wiring and secure parallel connections — up to 15 units can be linked for larger residential or light-commercial energy banks.
As with any home storage purchase, rated capacity (14.336kWh) isn’t automatically usable capacity — actual backup time depends on your inverter’s discharge limits, BMS reserve settings, and your household’s specific load profile. Backed by CB 62619, UN38.3, and CE-EMC certification, the W15-5A Foot Pad is a stable, code-conscious foundation for homeowners prioritizing predictable cycling behavior over headline kWh numbers alone.
