15kWh, LiFePO4，Photovoltaic energy storage battery
● Model: CN551601 – 51.2V 280Ah
● Chemical composition: Lithium iron phosphate
● It contains a lithium battery BMS inside, which can monitor the battery’s operating status in real time. When necessary, it provides protection against overcharging, overdischarging, overcurrent, overtemperature, etc., and when necessary, it cuts off the input and output of the power battery for protection.
