Deye SE-G5.1 Pro-B Rack Battery LiFePO4 5.12 kWh 51.2 V

The Deye SE-G5.1 Pro-B is a 5.12 kWh LiFePO4 battery at 51.2 V in rack format, 133 mm high and 440 mm wide, designed for cabinets and technical rooms. It is the module you build modular storage banks with for homes, offices and small businesses: start with one shelf and add modules as demand grows.

The integrated BMS handles protection and balancing and talks to the inverter over CAN 2.0 and RS485; paralleling reaches 64 units (32 without external setup) for more than 320 kWh of system capacity. The cells are rated for over 6000 cycles at 70% remaining capacity and 16 MWh of total energy throughput, with a 10-year warranty and a certification list including CEI 0-21, IEC 62619, VDE 2510-50 and UL 9540. It pairs with Deye 48 V low-voltage hybrid inverters.
