LFP Series 4000W Pure Sine Wave Inverter/Charger

Overview

A compact, all-in-one power solution. This LFP series unit combines an inverter, battery charger, and AC auto-transfer switch. It runs from a 12V battery, accepts 240V input, and can output 120V or 240V with 50/60Hz options. It’s designed for efficiency, remote control, and easy integration into off-grid or backup systems.

Benefits

• 4000W continuous power with high surge capability for startup peaks.
• Output selectable as 120V or 240V, plus 50/60Hz support.
