Deye SS-F10/F5

A 10 kWh high-voltage (512 V) LiFePO4 wall battery with IP65 protection, charging down to -20 degrees Celsius and up to six units in parallel for a stated 60 kWh.

Models Covered: DEYE-SS-F10, DEYE-SS-F5

Manufacturer: Ningbo Deye Inverter Technology Co., Ltd

Application: High-voltage architecture keeps currents small and cables thin: at 512 V nominal, the Deye SS-F10 moves 10 kWh with a maximum of just 20 A, operating across a 448-584 V window with high-voltage battery inverters. The IP65 enclosure shrugs off dust and water, and the pack both charges and discharges from -20 to 55 degrees Celsius - cold mornings included - with humidity tolerance up to 100%. Six units can parallel into a stated 60 kWh system. A master-slave BMS with passive balancing manages the LiFePO4 cells, optional DC arc detection adds a further safeguard, and SOC plus fault codes surface on the indicator. Rated beyond 6,000 cycles to 70% end-of-life capacity with a recommended 90% depth of discharge, the 85 kg, 850 x 650 x 170 mm slab mounts on a wall or floor and carries a stated 10-year warranty. Communication with the inverter runs over CAN2.0 and RS485.
