Features to know about

PowerMax 50A power center and distribution panel held by human for scale.

What a Power Center Does When Everything Feels Off

In larger RVs, power problems tend to show up as flickering lights, batteries that never quite catch up, or systems that struggle under load. This power center manages incoming AC power, distributes DC power throughout the RV, and converts AC to 12V DC to keep batteries charged. When it's working properly, everyday systems feel stable instead of acting strangely under load.

Wireless Control That Fits How You Use Your RV

Built-in wireless capability allows you to control selected circuits, including awnings, slide-outs, and lighting, directly from a smartphone app. This makes it easier to manage everyday tasks without running back and forth between switches, especially when setting up camp or adjusting things from inside the RV.

Battery Support With User-Controlled Charging

This power center supports lead acid, AGM, and lithium batteries, but different batteries require different charging behavior. In 3-stage mode, the converter cycles through boost, normal, and storage stages to recharge and maintain lead acid and AGM batteries. For lithium batteries or setups that need a specific charging voltage, the adjustable output mode lets you manually set a fixed voltage based on the battery manufacturer's recommendations.

Designed to Manage Heat, Noise, and Service Access

Higher-output converters generate more heat, especially in 50A systems. A temperature-controlled fan responds as needed to manage internal heat without running constantly. LED indicators at the DC fuse panel help identify blown fuses quickly, making service and troubleshooting more straightforward.

  • How To Select RV Power Center Box With Converter On DIY Build
    Ethan, if you’re not constrained by the original cutout, the decision really comes down to shore power rating and battery needs. -Choose the # PM47VR if you’re on 30-amp service with light duty 12V loads (12v led lights, fan etc.) -Step up to the # PM67VR if you’re still on 30-amp service but want stronger battery charging or power for more accessories. -Go with the # PM77VR if your RV or build uses 50-amp service and you want higher capacity plus modern features like wireless control.

  • Upgrading To Lithium Batteries In RV - Do I Need To Replace Power Center Or Converter?
    Natalie, that depends on how your RV is set up. If your existing power center has a converter that isn’t lithium-friendly and can’t be replaced on its own, swapping the entire power center can be the cleanest solution. Units like the PowerMax 45A # PM47VR, 55A # PM67VR, and 60A # PM77VR support lithium batteries and let you adjust charging behavior, so they’re often chosen when upgrading from older WFCO power centers like the WF-8945, WF-8955, or WF-8900 series. If your current power...

  • Can PowerMax PM77VR Power Center With Converter Replace Older WFCO 8900 Series Power Center?
    Yes, Daniel - the PowerMax power center with converter # PM77VR is designed to replace older WFCO 8900-series power centers WF-8900 PEC in 50-amp RVs. It’s a full 50-amp AC/DC power center with a built-in 60-amp DC converter, so it handles shore power distribution, 12V loads, and battery charging in one unit. What sets the # PM77VR apart is that it also adds wireless control for certain RV circuits (awnings, slide outs, lights etc. using smartphone app), which most older 8900-series panels...

  • Electrical Panel Box With AC To DC Converter For RV / Cargo Trailer Remodel
    Ryan, absolutely - if you’re open to modifying the cutout or building fresh cabinetry, power centers like the PowerMax 45A # PM47VR, 55A # PM67VR, or 60A # PM77VR work very well in custom builds and remodels. In those cases, the exact replacement list WF-8945, WF-8955, WF-8900, etc. matters less because you’re not constrained by the original opening. What does matter is matching the AC service 30-amp vs 50-amp and choosing a DC converter size that fits your battery setup. Many DIY builders...

  • What Does RV Converter Power Center Do Compared To Standalone AC To DC Converter?
    Mike, an all-in-one RV power center like the PowerMax 45A # PM47VR, 55A # PM67VR, or 60A # PM77VR replaces the entire electrical panel / hub in your RV - not just the converter section. These units combine the AC breaker panel, DC fuse panel, and converter/charger into one housing. Sometimes converters are part of this assembly, or they can be standalone converters; it just depends what you have. Most units with standalone converters are on smaller, lower capacity setups.
