WFCO WF-5300 Series Pure Sine Wave Inverter with Built-In Transfer Relay

The newly launched inverter delivers innovative power management with excellent performance and efficiency.

The internal transfer system instantly supplies inverter power if external AC fails. Key features include a remote-control panel with status readouts, pure sine wave output for sensitive RV electronics, overload protection, easy AC wiring terminals, and a hi-pot design for checking output circuits without rewiring.

With over a decade of inverter manufacturing, WFCO focuses on reliability, clean signal, easy installation, and intelligent power management.
