Product overview
Sunsynk SUN-BATT-5.32R – 5.32kWh Rack Mounted Battery
Sunsynk SUN-BATT-5.32R is a high-performance LiFePO4 battery for residential and small commercial energy storage. It delivers reliable, efficient power with a 45.6V–56.16V range, fully compatible with 48V hybrid inverters. Supporting up to 80% depth of discharge, it maximises usable energy while protecting long-term battery health. Its intelligent BMS monitors voltage, current and temperature, with safeguards against overcharge, over-discharge, over-current, and extreme temperatures. Up to 8 units can be connected in parallel for scalable capacity, and quick paralleling with no dip switches simplifies installation. 1C charge/discharge (0.5C in the UK) allows full use of stored energy.
