Description
W15-5A battery from Lithium Valley, engineered for homeowners and small commercial sites that want serious energy storage without the complexity of stacking multiple smaller battery units. Built on Lithium Iron Phosphate (LiFePO4) chemistry, it combines a large single-module energy reservoir with a sleek, space-saving wall-mounted design suited to utility rooms, garages, or dedicated plant spaces.
At the core of the W15-5A is a rated capacity of 280Ah at 51.2V nominal voltage, delivering 14,336Wh of usable energy — enough to run heavy household or light commercial loads such as HVAC systems, refrigeration, security systems, and entertainment equipment through the night or during extended grid outages. Rated for 6,000+ cycles at 80% depth of discharge, the W15-5A is built as a long-term energy investment with minimal maintenance, no acid leaks, and no water-topping requirements.
An integrated LED display gives real-time visibility into state of charge (SOC) and battery health, while a quick plug-in terminal system for the +/- connections simplifies installation and ensures secure, spark-free wiring. For growing energy needs, the W15-5A supports parallel connection of up to 15 units, scaling total storage capacity to well over 200kWh for larger residential estates or commercial applications. CAN and RS485 communication interfaces ensure smooth integration with leading hybrid inverter brands, while a dedicated RS232 port supports technical debugging and performance monitoring.
Rated IP54 for indoor and protected environments, and backed by international safety certifications (CB 62619, UN38.3, CE-EMC), the W15-5A is a dependable, scalable battery solution for anyone serious about reducing electricity bills, shifting solar energy to peak-tariff hours, or achieving true off-grid independence.
