SunGold Power | 12000W 48V Split Phase Pure Sine Wave Inverter Charger | LFPV12K48V240VSP

SunGold Power 12000W 48V Split Phase Pure Sine Wave Inverter Charger

When 6KW is not enough, this 12000W split phase inverter charger picks up where smaller units stop. The SunGold Power LF-PV series delivers 12KW of continuous pure sine wave power from a 48V battery bank - enough to run refrigerators, freezers, air conditioners, dryers, pumps, and microwaves simultaneously. With a 36KW surge rating, it handles the brutal startup demands of multiple motor-driven appliances without tripping or clipping.

The LF-PV 12KW combines an inverter, a 120-amp battery charger, and an automatic transfer switch in a single heavy-duty chassis. It supports eight battery types including LiFePO4, gel, AGM, and lead acid, and features 4-step intelligent charging with PFC correction for maximum charging efficiency. Transfer time between utility and battery power is 10 milliseconds max. At 160 lbs, this is a serious piece of power infrastructure - built for permanent installations in homes, shops, and commercial applications where downtime is not an option.
