Will this converter power my RV’s 12V appliances and charge the house battery?

Yes — the WF-9855 delivers a continuous DC output at 13.6V and up to 55 amps, enough for lighting, fans, water pumps, and battery charging simultaneously depending on load. It converts standard AC shore power into regulated DC suitable for most coach electrical systems.

How does the WF-9855 keep my RV electronics protected?

The unit integrates multiple safety features to reduce risk to appliances and wiring. It monitors current and temperature, shutting down or limiting output if conditions exceed safe thresholds to avoid damage or fire risk.

• Over-current and short-circuit protection with electronic current limiting
• Over-voltage protection to prevent excessive DC output
• High-temperature shutdown to protect internal components
• Quiet, upgraded cooling fan that reduces interference with radios and TVs

Is the WF-9855 compatible with my RV model and easy to install?
