Upgrade your RV power center with 35 amps of smart charging. Auto-Detect senses lead acid or lithium batteries, adjusts the charge profile, and helps protect your battery from overcharging or undercharging.


Highlights

  • Auto-Detect Charging for Lead Acid or Lithium: Charging profiles switch automatically between compatible battery types without manual settings.
  • 35-Amp Output Supports Full RV Power Distribution: Powers 10 AC circuits and 11 DC branch circuits from one centralized power center.
  • Multi-Stage Charging Reduces Battery Wear: Bulk, absorption, and float charging modes manage voltage from 13.2V DC to 14.6V DC.
  • Microprocessor-Controlled Charging Removes Manual Switching: Battery charging adjusts automatically as your RV's power demands change.
  • Built-In Circuit Protection Handles Electrical Faults: Reverse polarity, overload, short circuit, and over-temperature protection shut down unsafe conditions.
  • Twin Breaker Compatibility Expands AC Circuit Capacity: Supports additional branch circuit flexibility in RVs with heavier AC power demands.

Features to know about

Automatic Charging for Mixed Battery Upgrades

Battery upgrades usually create charging problems when older converter systems can't recognize lithium batteries or require manual setting changes to work correctly. Auto-Detect technology identifies compatible lead acid or lithium-ion batteries and automatically switches charging profiles without external controls or dip switches. Your battery charging stays matched to the installed battery type instead of relying on manual setup every time the system changes.

35 Amps of DC Power for Daily RV Loads

Multiple lights, vent fans, water pumps, and charging devices running together can expose weak converter output during campground stays or longer trips. This power center delivers 35 amps of DC output with support for up to 10 AC circuits and 11 DC branch circuits from one centralized panel. Your RV's electrical system stays organized while core 12V equipment keeps operating under normal campsite demand.

Charging Modes That Reduce Battery Stress

Constant high-voltage charging shortens battery life fast, especially when your RV stays plugged into shore power for extended periods. The three-stage converter charger cycles through bulk, absorption, and float charging modes for lead acid batteries, while lithium charging uses a dedicated 2-stage profile with voltage output up to 14.6V DC. Your battery maintains proper charging behavior during storage, recovery, and active use instead of staying locked at one charging level.

Protection Systems That Respond to Electrical Faults

Electrical problems inside your RV can spread quickly when overloads, short circuits, or reversed battery connections hit the converter without protection built into the system. This unit includes reverse polarity, overload, short circuit, and over-temperature protection with automatic recovery under normal load conditions. Your power center shuts down unsafe electrical events before damage spreads through connected circuits.

Twin Breaker Support for Larger AC Setups

Adding appliances or expanding campground power distribution can fill standard breaker layouts fast in larger RV electrical systems. This power center supports twin breakers across its AC distribution section, allowing more branch circuit flexibility without moving to a larger panel footprint. Your RV can handle expanded AC circuit layouts while keeping the power center consolidated in one location.

Video Transcript for Review of WFCO Power Converter - 35 Amp RV Power Center - WF28FR

Hi everybody, Andy here with etrailer. Let's take a quick look at this WFCO 35 amp RV power center. Now this RV power center is going to combine your converter, battery charger, and AC/DC distribution panel into one unit, making it the central hub for your RV's electrical system. It's going to deliver 35 amps of DC output, which is enough to power your RV's 12 volt systems while managing up to 10 AC circuits and 11 DC branch circuits from a single organized panel. If your setup requires additional flexibility, this is going to also be compatible with twin breakers to expand your available AC branch circuits. Now one of the biggest advantages of this unit is going to be its built-in auto detect charging system.

It's going to automatically recognize whether you're using a lead acid or lithium battery and applies the proper charging profiles without requiring you to change any settings. The microprocessor controlled charger is going to continuously adjust charging based on your battery's condition and your RV's electrical demand so the system does the work for you. For lead acid batteries, this uses a three stage charging process, bulk, absorption, and float to recharge the battery quickly while helping reduce long term wear. Lithium batteries receive a dedicated two stage charging profile with charging voltages up to 14.6 volts, ensuring that they're charged efficiently without overcharging. This intelligent charging is going to help maximize battery performance and lifespan, whether you're plugged into shore power at a campground or preparing your RV for the next trip.

This unit also includes several built-in safety features to protect both your electrical system and your batteries. It's going to automatically guard against reverse polarity, overloads, short circuits, and overheating by shutting down the converter if an unsafe condition is detected. But overall, this power center is going to be a great choice for RV owners who are looking to modernize or replace their electrical system with a unit that's going to simplify battery charging, support both lead acid and lithium batteries automatically, and provide organized AC and DC power distribution and offers reliable protection for the entire electrical system. It's going to operate on 105 to 130 volts AC, provides 35 amps of continuous DC output, and features 10 AC circuits, one main and nine branch along with 11 DC branch circuits, making it well equipped for a wide range of RV electrical setups. Let me leave you with some measurements.

Looking at the length a little over 14 inches, looking at the height about a foot, a little under. And then the depth, the deepest point here I believe, right at about eight and a half inches deep. If there's any other information that you're looking for that I didn't cover with you, be sure to take a look at this product page. We do have some additional bits of info there listed. If you still have some questions, don't hesitate to give us a call.

One other thing I wanted to mention if you need some help with getting this installed, on this product page, typically underneath the photo section, we have a link that will take you to our installer locator. Click that link, answer the questions that it has for you and that locator will find an installer in your area that etrailer has partnered with to help you with the install. Well again, my name's Andy. Thank you for joining me.
