15kWh 300Ah 400V High Voltage Lithium Battery Pack
HDC15-5K consists of three key parts: a 51.2V lifepo4 battery module, a smart BMS, and a DC-DC boost module.
The 51.2V module is made by connecting 16 grade-A lithium iron phosphate cells in series. Through the DC-DC module, the 51.2V voltage is boosted to 400V, providing stable power to high-voltage loads. The smart BMS offers charge/discharge protection, and its natural cooling design helps keep the system safe and stable. Additionally, independent battery management allows quick response to sudden power demands from loads.
During the day, the 400V system stores extra power generated by solar panels. At night, it supplies electricity when needed. With peak and off-peak adjustment, you can take advantage of electricity price differences. This not only improves your energy independence, but also cuts your power bills for long-term savings.
