Deye SE-F12 Version C LiFePO4 Battery 12.03kWh 51.2V
The Deye SE-F12 is a LiFePO4 battery at 51.2V with 235Ah of capacity, the middle size of the SE-F family: enough energy to cover evening and night in a house with a heat pump, without the bulk and weight of the 16kWh modules.
What sets it apart is current: 230A continuous in charge and discharge, with 280A peaks for ten seconds, so there is no bottleneck when the hybrid inverter asks for all the power available. The integrated BMS talks over CAN 2.0 and RS485 and publishes data to the Bluetooth app, while paralleling up to 32 units lets the system grow over time. It installs on a wall, on the floor or stacked and works with Deye 48V low-voltage hybrid and off-grid inverters.
