Features to know about

Auto-Detect Battery Charging

The built-in microprocessor recognizes whether your system uses lithium or lead-acid batteries and automatically applies the correct charging profile. There are no switches to flip or modes to select when upgrading or replacing batteries.

Zero-Clearance Cooling Design

Front-to-front airflow and a 2-speed fan allow this power center to operate without rear clearance. That makes it easier to install in tight RV compartments while keeping components cool under load.

Do you have a question about this RV Power Converter?
  • How To Measure And Find Which WFCO AC/DC Fuse Box And Converter Is Needed For Travel Trailer
    Hey there Kevin, if you’re trying to avoid trimming or adding filler panels, matching orientation is the safest move, and it really comes down to checking the cutout size or the model converter you currently have. If your current panel is vertical (taller than wide), the # WFC72GR 40A is a common size, fitting a cutout of 7 13/16" Wide x 11 5/16" tall x 7 3/8" deep. If it’s more standard horizontal setup (wider than tall), then the # WF86FR 55A is a common size, fitting a cutout of 12-3/16"...

  • Can I replace my Progressive Dynamics power center with a new WFCO unit?
    Hey Jeff - yes, you absolutely can switch brands as long as you match the service rating and verify the cutout size so you don't have to make big changes to the cutout (trimming or filling a gap). All three of these models you were looking at - # WF46FR 40A horizontal, # WF86FR 55A horizontal, and # WFC72GR 40A vertical - are designed for standard 30A shore power setups. Not the heavier duty 50A found in bigger RVs. I recommend checking your cabinet opening size and orientation so you...

  • If My RV Lithium Battery Bank Is 300AH 12V, Is 40A Converter / Power Panel Enough?
    Good morning Dana. With a 300Ah lithium bank, a 40A converter / power panel like the one in the WFCO # WFC72GR will work - but recharge times will be longer compared to a higher-output unit. It really depends on what battery bank you have, and if you plan to stay hooked up to shore power or use a generator for a few hours where the batteries will need to charge up quickly. If your cabinet allows for the larger horizontal opening, the # WF86FR 55A will recharge a larger battery bank noticeably...

  • Which WFCO RV Converter Power Center Can Handle More DC Circuits With Added Fuse Slots? 30A Shore
    Hello Ryan, that’s where the WFCO rv converter / power distribution panel # WFC72GR really stands out. While both the # WF46FR and # WF86FR give you standard AC/DC distribution, the # WFC72GR provides: -13 DC circuits (3 at 30A max, 10 at 20A max) -Up to 9 AC branch circuits, 1 main 30a AC circuit. It’s designed for builds that need more circuits like in your situation. Just note it has a different footprint than the others - rough opening is 7-13/16 inch Wide x 11-5/16 inch Tall x 7-3/8...

  • Do WFCO RV Converter Power Center Panels Work With Lithium?
    Hey Daniel! That’s one of the benefits of these newer WFCO Auto-Detect panels. You won't need to replace anything again since they are compatible with lithium. The new models like # WF46FR, # WF86FR, and # WFC72GR all automatically detect lithium batteries and apply the proper charging profile. No switches or internal settings required. If you’re planning a larger bank 200Ah+, you may eventually wish you had gone with the 55A model for faster recovery - but functionally, the 40A unit...

  • How To Select Correct WFCO Power Center On 30A Shore Hookup In 2016 Heartland RV ?
    Hey Kevin! With power centers, fitment matters just as much as amperage. Here’s a quick breakdown on the cut-out that is required for a few popular models that work on 30A hookup: - # WF46FR (40A – horizontal layout) Rough opening: 10-3/8" Width x 4-1/8" Depth x 7" Height - # WF86FR (55A – horizontal layout) Rough opening: 12-3/16" wide x 11" tall. - # WFC72GR (40A – vertical layout) Rough opening: 7-13/16" Width x 7-3/8" Depth x 11-5/16" Height So before choosing based on charging capacity,...

  • Replacement Options For RV Power Panel That Is Taller Rather Than Standard Wider Style
    Hey Chris - if your existing panel is taller than it is wide, that usually means you’re looking for a vertical-style replacement. The WFCO # WFC72GR 40A power distribution panel installs in a vertical orientation and requires a rough opening of: 7-13/16 inch Width x 7-3/8 inch Depth x 11-5/16 inch Height That taller layout makes it ideal for cabinets or cutouts where width is limited but height is available. What are the rough measurements of your cutout? I can make sure this is the...

  • Does The Vertical Mount WFCO RV Converter Power Center WFC72GR 40A Work On 30A Shore Power?
    Not a problem at all, Kyle. The WFCO RV converter power panel # WFC72GR is still a 30A main breaker power center. The “40A” rating refers to DC charging output - not shore power input. I know, it's confusing haha. The vertical orientation simply gives you more DC fuse circuits 13 total and more AC branch options. It installs taller than wide, so just make sure your cabinet opening supports the cutout requirement of 7-13/16" wide x 7-3/8" deep x 11-5/16" tall. If it's going to require...

  • Does WFCO RV Converter Power Center Have Enough DC Circuits For Extra Accessories In The RV?
    Hey Ryan! Yes - that’s actually where the WFCO RV Converter / Power Center # WFC72GR really shines. It provides: -13 DC fuse circuits (3 circuits rated up to 30A, 10 circuits rated up to 20A) -Up to 9 AC branch circuits -30A main breaker That bigger DC fuse layout makes it ideal for additional circuits like slide-outs, powered stabilizers, extra lighting, stereo systems, cameras, etc. Because it installs vertically, it fits cabinets that are taller than wide. The cutout size required...

  • Is 40A Or 55A Converter Power Center Better For 2 12V Batteries In Parallel In Camper?
    Hi Brandon, with two 12V batteries wired in parallel, stepping up to the WFCO RV converter AC/DC power center # WF86FR 55A makes sense. The extra 15 amps of DC charging capacity helps recover the bank faster - especially if you need to charge quickly such as on short generator runs. One thing I'd check is your converter cutout space to make sure you won't have to do lots of trimming or modifications (sometimes it is inevitable though). This unit requires a hole sized to 12-3/16" wide x...
