Powerful, Reliable RV Power on the Go

The WF-9855 55A deck-mount charger/converter is designed to replace a worn unit in the popular 9800 Series. It offers a practical, cost-saving upgrade for RVs, trailers, and campers that rely on a steady supply of DC power while traveling or camping. The compact, durable housing is built for on-road use, and the installation process is straightforward for typical RV electrical layouts.

Key Benefits at a Glance

  • 55 amps of clean DC power deliver energy to essential electronics and appliances without a major rework.
  • Stable power that minimizes interference with televisions, radios, or other onboard signal equipment.
  • Electronic current limiting protects circuits during overload or short-circuit events, reducing risk during busy power draws.
  • Quiet operation thanks to an intelligent cooling fan that only runs when needed.

Smart Charging and Battery Care

The WF-9855 includes automatic three-stage charging with three nominal voltage output modes. This setup is designed to provide reliable charging while supporting different battery states, so you have flexibility on long trips and in remote sites.

  • Automatic three-stage charging helps manage battery health and readiness for the next excursion.
  • Three nominal voltage outputs offer compatibility with varying battery configurations and load needs.

Why It Fits the 9800 Series and Your RV Life

As a replacement part, the WF-9855 offers a budget-friendly option that avoids swapping an entire unit. It’s compatible with a wide range of recreational vehicles, from compact trailers to larger campers, making it a practical upgrade when the original controller is aging or hard to source.

Real-world scenarios where this converter shines include weekend getaways, full-time RV living, and remote campouts where dependable DC power helps keep devices charged, cameras ready, and meal prep on track. The durable build and smart safety features provide peace of mind, while the compact deck-mount form saves space in tight electrical bays.
