rv power center

This RV power control center combines an AC/DC panel with a multifunction 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. It's compatible with lithium and lead acid batteries.


AC/DC Electrical Distribution

internal view

The panel supplies AC and DC distribution to your RV's electrical system. The AC section includes space for up to 6 breakers rated for 240V at 50 amps. This lets you have up to 12 branch circuits when you use tandem breakers. The DC section has 18 branch fuse holders capable of using (4) 30 amp and (14) 20 amp fuses. Also, this section has lever lock connectors to make wiring faster and more secure. Simply open the lever, insert the wire, and close. You will need to purchase AC breakers and DC fuses separately to complete the installation.


internal view

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.


Multifunctional Converter Charger

switch charging mode

The integrated converter charger changes AC shore power into DC power to charge your battery bank. It includes an output mode switch that lets you choose either lithium or lead acid batteries. No matter what type of battery is installed in your RV, you'll always have the most efficient charging profile. If your RV already has a stock converter charger, it will need to be removed to ensure this unit operates properly.


Charge Wizard for Lead Acid Batteries

In lithium mode, the unit uses a higher output voltage, which provides a fast, complete charge. It also extends battery life since it utilizes the appropriate charging profile. Additionally, this mode is compatible with your battery's internal Battery Management System (BMS), which helps manage the charge cycle by monitoring the battery state and balancing cell voltage.


Charge Wizard for Lead Acid Batteries

In lead acid mode, the Charge Wizard automatically switches voltages while your lead acid battery bank charges. This accelerates the charge but also helps extend battery life by adjusting the voltage during the different modes. This function 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 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.

I used this item to upgrade my 30 amp travel trailer to 50 amp. I am very pleased with how easy it was to use, it arrived when expected, and has worked flawlessly.



by:

Placed my order on the 5th with an expected delivery date on the 10th. I had to hassle the staff to actually ship my order with excuses ranging from low staff in warehouse and order fulfillment. Then later on the 12th called and got told that anyone that payed for over night shipping or any higher than free shipping would jump the line and that’s why my order kept getting delayed. That is unexceptional practice when you establish a ship date. When I received the box it had a giant cut in the side of the box. I haven’t found out if the product is damaged yet or not.

We always want to ship our orders as quickly as possible and we want the boxes to arrive in good shape. I will have our Customer Service team reach out to you case there was any damage to the converter.



by:

Perfect replacement that allows me to convert RV to lithium batteries.



by:

Received order as promised, I am replacing a 120volt unit with this 240v unit so I can add an additional AC on other circuits to use trailer as a mobile office. Has options for acid batteries or lithium batteries. Seems well built and should be easy to change out

Installed this one year ago and is working perfectly. using in lead acid mode and like the option to change to lithium option if desired.

I have a few comments for e-trailer.
-When
I called to get the optional neutral bus bar for the AC side of this center, the rep did not know what I was talking about. Maybe y'all can just send me that.
-I attached pictures of how my product was boxed/shipped. It is hard to stop the carrier from damaging the box which was somewhat mangled. But the unit was not packed with any foam, plastic bag or packing material to protect it during shipping. It was just tossed in a box. It looked as if the cover and the converter bounced around inside the box. Hopefully, Etrailer packs future shipments better.

Switching to 50amp best thing I’ve done for my trailer. Have had no issues with this product at all



by:

I haven't installed it yet but it seems straightforward. 4 stars because no fuses or breakers were included.(as mentioned before purchasing) That's like buying a flashlight with no batteries in my opinion.



by:
