Product Description


WFCO’s 2000 Watt power inverter, WF-5220, is engineered for outstanding performance. It provides high-efficiency power at full-load conditions with safeguards that include overload protection, over-temperature protection, short-circuit protection, and reverse polarity protection.

The WF-5220 features an automatic transfer switch, pure sine wave output, hi-tech filtering for premium electronics and refrigerators, and an easy hi-pot testing design. The inverter also has LED status indicators, reverse polarity protection with light indicator, WAGO AC hookup, as well as a remote-control system. Using the latest high-frequency technology, WFCO’s new WF-5220 inverter is lighter and more efficient than other brands.  Designed with production in mind, installing an inverter has never been easier.
