WFCO/ Arterra Power 1000 Watt Inverter w/ Reverse Polarity Protection and Short Circuit Protection

Our newest inverter overcomes the simple and common problem of improper hook up between the inverter and batteries that can happen during installation or service. The WF-5110R has been equipped with reverse polarity protection to safeguard the batteries, inverter and other coach electronics in the event that the batteries are connected to the inverter backwards.

Typically, when a battery is connected, and the polarity is reversed from what it should be, the electrical system becomes damaged, which is very costly. The WF-5110R has built-in reverse polarity protection. When the battery is connected incorrectly, nothing will become damaged, the technician can simply reconnect the battery correctly and everything will work as it should.


With over a decade of inverter manufacturing, WFCO knows what is important. Reverse polarity protection is just one example of this understanding. We are proud to offer this in addition to our many other customer friendly features:

- Improved Conversion Efficiency

- Auto Shut Down when Batteries are Low

- LCD Message Screen and Status Indicators, with Remote Control

- Built-In Circuit Protection on the DC Side

- Pure Sine Wave Output


Working hand in hand with dealers and technicians to develop products that support the advancement of the industry is WFCO’s commitment and contribution to its customers.

WFCO supports RV technicians by offering workshops and training seminars with in-depth training on WFCO’s product line. The goal of the training is to help dealership’s better sell, replace, and troubleshoot WFCO products, including the WF-5110R.
