WFCO 9800 Series (WF-9800-AD) Deck Mount Converter / Charger

The WFCO 9800 Series (WF-9800-AD) converters deliver clean, dependable 12V DC power for your RV’s lights, controls, and accessories—while also providing multi-stage battery charging when you’re on shore power or generator power. These deck-mount converters are designed to pair well with RV distribution panels/centers and are a popular replacement/upgrade when you need reliable charging performance.

A standout feature of the WF-9800-AD series is Auto-Detect charging: the converter recognizes Lithium-Ion vs Lead-Acid battery chemistry and automatically adjusts the charging profile—no switches or buttons required.

All models include built-in protections and a cooling fan that runs only when needed for quieter operation.
