Highlights
True 120/240V split phase, 6,000W - Three 20A outlets and one 30A, pure sine wave. The 240V leg allows operation of a well pump, a compressor or a 240V tool without a transformer.
3,600Wh LiFePO4, rated 3,500 cycles to 80% - Lithium iron phosphate chemistry. Rated for approximately 10 years at one cycle per day.
Expandable to 57.6kWh - Supports up to fifteen BP3600 batteries alongside the built-in 3,600Wh capacity.
Recharges in approximately 1.96 hours at the full 2,200W AC input. Solar, car and generator charging are supported, with simultaneous AC and solar input capability.
Indoor operation - Produces no fumes or carbon monoxide, suitable for indoor placement.
App monitoring over WiFi and Bluetooth - Provides live draw, state of charge and settings management via mobile device.
Eight-layer BMS and a 4-year manufacturer's warranty - Includes protection against overcharge, over-discharge, short circuit, over-voltage and temperature excursion.
Materials & care
To protect the LiFePO4 battery cells, ensure the unit is stored and charged in environments above 32°F (0°C). Keep ports clean and dry, and operate within the recommended temperature range of 68°F to 86°F for optimal lifespan.
