The floor-standing 16KWh energy storage battery adopts LiFePO4 cells, whose stable material structure enables long cycle life. The crystal structure of LiFePO4 hardly collapses under repeated deep charge and discharge, achieving more than 6000 cycles under standard conditions. The vertical cabinet is designed with heat dissipation channels and temperature control to reduce operating temperature and slow cell aging. High-precision BMS performs active balancing to minimize cell voltage difference and maintain good consistency. With 16KWh capacity, it supports solar self-consumption and peak-valley arbitrage for homes. Compared with lead-acid batteries, it has smaller size, 3-4 times longer lifespan and zero maintenance, making it a new-generation long-life energy storage device.
