SunGold Power | 15000W 48V Split Phase Pure Sine Wave Inverter Charger | LFPV15K48V240VSP

SunGold Power 15000W 48V Split Phase Pure Sine Wave Inverter Charger

This is the unit you reach for when your power demands outgrow everything else. The SunGold Power LF-PV 15000W split phase inverter charger delivers 15KW of continuous pure sine wave power from a 48V battery bank, with a 45KW surge rating that absorbs the startup punishment of multiple large appliances running simultaneously. Air conditioners, well pumps, dryers, commercial refrigeration - this inverter handles the full electrical load of a standard-size home or a demanding commercial space.

Like its 12KW sibling, the 15KW LF-PV integrates an inverter, a 100-amp battery charger, and an automatic transfer switch into a single chassis. It supports eight battery types, features 4-step intelligent charging with PFC, and transfers between grid and battery in 10 milliseconds. At 176 lbs with a 45KW surge ceiling, this is built for permanent installations where you need serious, uninterrupted power capacity and zero compromises on waveform quality.
