WFCO News and Updates

WFCO expertise in power conversion technology has delivered what is becoming the power option of choice for residential refrigerators in larger RVs. Now WFCO has just released an upgrade to its popular WF-5110H inverter, a 1,000-Watt pure sine wave inverter that provides the electrical filtering needed for such refrigerators.

WFCO’s WF-5110HP, which simplifies and provides certainty in product testing on the RV production line, replaces the WF-5110H model. As with the WF-5110H, the WF-5110HP features a plug-and-play design that allows it to be simply plugged into an AC outlet to connect directly to the RV’s AC system. It will convert 12 V DC to 110 V AC, and has a remote control system and built-in circuit protection on the AC side.

“The 5110HP is exactly what manufacturers tell us they are seeking to power sensitive 110-volt appliances like residential refrigerators,” said Jack Cheng, WFCO CEO. “We will be developing more inverter models as such technology is becoming a more important element in the design of larger RVs. Success we’ve had with the WF-5110H confirms we’re in synch with where the industry is going.”

While propane-electric absorption refrigerators have previously dominated the industry, popular features in 110-volt refrigerators, coupled with advancements in inverter technology like the 5110HP and the availability of “shore power” at more campgrounds has increased demand for residential refrigerators in RVs. When adequate AC shore power is unavailable and when generator noise is inappropriate inverter technology is the ideal solution.

The features on the WF-5110HP that RV manufacturers like include an Internal Transfer Switch that allows AC input to bypass the inverter when the RV is connected to an AC source, either shore power or generator power. So there’s no need to install an external switch. This inverter also protects the battery by automatically shutting down when batteries run low and input is below 10 volts.

Furthermore, the WF-5110HP allows manufacturers the use of more cost effective 4-gauge wiring versus 2-gauge wire. With no crimping required, 4-gauge wire connections are also much easier and quicker for installers.

“We are continually working with our manufacturing partners to give them the best products and best value for their needs, ” said Cheng. “So this seamless product upgrade enhances the OEM’s manufacturing process as well as its product.”
