DEYE low voltage LiFeP04 battery,102.4Vdc,40Ah,4kWh

The Deye 4 kWh high-voltage LiFePO4 battery is a modular energy storage solution designed for modern hybrid and off-grid photovoltaic systems. Part of Deye's high-voltage ESS solutions, this battery module offers excellent efficiency, reliability and flexible expandability.

The battery uses LiFePO4 (lithium-iron-phosphate) technology, which guarantees high safety, long service life and stable operation even with intensive use. It is suitable for both residential and small commercial applications.

The modular design allows multiple batteries to be easily connected in series, building a higher capacity high voltage system. This makes it extremely flexible when designing energy systems according to customer needs.

The integrated BMS system provides intelligent cell management, protection and balance, as well as communication with the inverter for optimal operation of the entire system.
