WFCO 55A RV Converter/Charger Deckmount — Auto Detect for Lead‑Acid & Lithium, Multi‑Stage Charging

The WF-9855 from WFCO is a compact, FCC-compliant converter/charger engineered to power RV systems and maintain battery health without manual setup. Its patented Auto Detect™ technology recognizes battery chemistry and applies the appropriate charging stages, while quiet, demand-driven cooling and electronic current limiting protect both the unit and connected equipment. Built to perform at lower shore voltages and certified to UL/CSA standards, the WF-9855 focuses on reliability and safe charging wherever you camp.

How does the WF-9855 keep my RV electronics running smoothly?

The WF-9855 outputs up to 55 amps of regulated DC power designed to run lights, appliances, and sensitive electronics. It reduces electrical noise, so audio and video gear operate without interference, and FCC Class B compliance limits radio/TV disturbance.

• 55 A continuous DC output for appliances and loads
• Clean, low-noise power suitable for sensitive devices
• Cooling fan that runs only when needed to reduce noise
• FCC Class B compliance to prevent signal interference

What charging features protect and extend my battery life?

WFCO’s intelligent multi-stage charging handles bulk, absorption, and float phases to support proper battery conditioning. The Auto Detect™ system automatically identifies lead‑acid versus lithium chemistries and applies the correct voltage and charge profile—no switches or manual selection required.

• Automatic bulk (14.4 V range), absorption (13.6 V range), and float (13.2 V range)
• Patented Auto Detect™ recognizes lead acid or LiFePO4 batteries
• Electronic current limiting protects against overloads and short circuits
• Multi-stage charging helps reduce overcharging and sulfation risks

Will this converter work reliably at low campground voltages?

The WF-9855 is specified to deliver full output even when input voltage is as low as 100 VAC, addressing a common RV campground problem. That means faster, more consistent charging and stable system performance when shore power is weak.

• Maintains full output down to 100 VAC input
• Prevents slow charge rates caused by low shore voltage
• Improves appliance and system reliability in marginal power sites

What safety and compliance credentials does the WF-9855 have?

WFCO designs the WF-9855 to meet recognized safety and emissions standards to protect both users and equipment. Certifications and features support long-term reliability and safe operation in mobile environments.

• UL and CSA listed for safety and performance
• FCC Class B compliant for electromagnetic emissions
• Electronic short- and overload protection with automatic shutdown

Who this is for: The WF-9855 is aimed at RV owners, installers, and OEMs who need a dependable deckmount converter/charger that supports both lead‑acid and lithium battery banks without user intervention. It's also a strong choice for those who frequently camp where shore power is unstable, or anyone requiring quiet operation and industry-standard certifications for peace of mind.
