Product Description


WFCO’s 2000 Watt power inverter, WF-5120, 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 cooling fan enhances efficiency as its operation is controlled by the amount of load incurred by the inverter.

The WF-5120 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 that display battery charge and inverter load levels, a low battery indicator, as well as a remote-control system that features the same display menu as the unit.
