rv power center

This RV power control center combines an AC/DC panel with a smart converter charger. Creating easy access to your electrical connections, this all-in-one breaker box distributes AC and DC loads to your RV and charges your batteries while connected to shore power. The integrated converter charger also uses the Charge Wizard to help extend battery life.

AC/DC Electrical Distribution

internal view

The panel supplies AC and DC distribution to your RV's electrical system. The AC section includes 5 branch circuits rated for 120V at 30 amps. The DC section has 6 branch fuse holders capable of using (1) 40 amp and (6) 30 amp fuses. However, you will need to purchase AC breakers and DC fuses separately to complete the installation.

inside cover

Once all of your connections are made, the breakers and fuses are easily accessible by opening the door on the front of the box. The door also includes a blank label to list all of the connections.

Smart Converter Charger with Charge Wizard

The built-in smart converter charger converts AC shore power into DC power and includes the Charge Wizard automatic multistage charging system to charge your battery bank. If your RV already has a stock converter charger, it will need to be removed to ensure this unit operates properly. Using the Charge Wizard, the converter charger automatically switches voltages while the battery bank charges. This accelerates the charge, but also helps extend battery life by adjusting the voltage during the different modes. This charger is compatible with flooded lead acid, AGM, and gel batteries.

Charging Modes

  1. Boost: This mode charges at the full rated load for a quicker recharge time. This is where most of the charging happens. It charges the battery up to 90% of the full capacity.
  2. Normal: This mode provides controlled voltage to ensure a full charge. Once the battery begins to reach capacity, the normal state will kick in and reduce the voltage to safely complete the charge.
  3. Storage: Once the battery reaches full charge and remains unused for 30 hours, this mode maintains a lower voltage to compensate for self-discharge. This reduces battery stress and minimizes gassing and water loss.
  4. Equalization: This mode activates to prevent stratification and sulfate buildup during extended storage cycles. These two issues can damage a battery by causing the accumulation of acid at the bottom of the battery and hardened sulfate crystals on the battery plates. This mode is especially helpful when your battery is going unused during storage.

Safety Features

internal view

The system includes a number of safety features. It has a reverse polarity protection that will protect the converter if the battery is hooked up incorrectly. Additionally, the unit includes protection for overvoltage, undervoltage, and overcurrent, which can damage your equipment, as well as the converter. The built-in cooling fan also removes excess heat from the unit. The fan speed is proportional to the internal temperature of the converter, so when the power demand is low, the fan will operate quietly.

Used this to replace an old junky converter in my Coleman pop up camper. Pretty easy to install and my batteries are much healthier because of it. 916373

I had my son-in-law who is an electrician install the converter. The converter is working good and the battery charge was really good. I believe that the water pump pressure was the best I had in a long time which indicates how well the battery is charged. The reason I gave 4 stars instead of 5 is that I think that a better manual could of come with the converter. When I connected the battery there was a green flashing light that I didn't know what it meant but after an internet search I found out what it meant. E-trailer was great to deal with, fast service and answered my questions quickly, 898589

So far so good! I build my own power center modeled after the ones in RV for our enclosed trailer. Its been working great. I bought fuses at the auto parts store, and bought circuit breakers at home depot no problem. I did contact progressive dynamics because it seems that there are places you can buy these cheap but the serial number is not recognized by progressive dynamics meaning you have no warranty and probably cant return it to those places. But since etrailer was not listed on progressive dynamics website as a retailer, I contacted them, gave them my serial number, and they confirmed that etrialer is a preferred dealer, and my serial number is legit.... I contacted progressive dynamics also during installation, and they were very helpful. I was concerned the the wire coming out of the unit that hooks up to your 12 v batteries was 12AWG. I though that seemed too light a gauge, and should be at least 10AWG maybe 8AWG. Progressive dynamics, technical guy said that they have a special high temp insulation on those wires and they can indeed handle 40 AMPS. He recommended (which looks odd installed) but I ran 8AWG from my battery, and spliced it to the 12AWG wire on progressive dynamics unit. No Complaints so far, its been running great and charging the batteries. No regrets. 854787
