Description
W10-5A battery from Shanghai STIN Energy, engineered as a wall-mounted or floor-standing home energy storage solution for residential and light commercial solar systems. Built around Lithium Iron Phosphate (LFP) chemistry, this battery delivers stable, long-lasting energy storage with an intelligent Battery Management System (BMS) that monitors and optimizes performance in real time, extends service life, and enables remote tracking via a mobile app.
At the core of the W10-5A is a rated capacity of 200Ah at 51.2V nominal voltage, delivering 10,240Wh of usable energy — enough to power a household through the night or bridge a grid outage. Rated for an impressive 8,000 cycles at 80% depth of discharge, the W10-5A is built for serious long-term daily cycling, with a recommended charge/discharge current of 100A and a maximum continuous rating of 200A (surging to 250A for 10 seconds) for demanding load conditions. Conversion efficiency reaches 99%, ensuring minimal energy loss between charging and discharge.
Communication is handled via CAN, RS485, or RS232 protocols, giving installers flexible integration with a wide range of hybrid, on-grid, and off-grid inverter brands. The battery is scalable up to 20 units in parallel for larger residential or small commercial energy storage banks, and optional expansion features include single-pack level heat aerosol fire extinguishing and a built-in heating function for reliable operation in cold climates — extending the safe charging range down to –20°C.
Rated IP65 for installation indoors or under outdoor eaves, and backed by international certifications (UN38.3, MSDS, TCAR, CB, CE-EMC), the W10-5A is a robust, scalable choice for homeowners and installers who need dependable, high-capacity solar energy storage with room to grow.
