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. It's compatible with lithium and lead acid batteries.
The panel supplies AC and DC distribution to your RV's electrical system. The AC section has space for up to 3 breakers rated for 120V at 30 amps. This lets you have up to 6 branch circuits when you use tandem breakers. The DC section has 12 branch fuse holders capable of using (2) 30 amp and (10) 20 amp fuses. However, you will need to purchase AC breakers and DC fuses separately to complete the installation.
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.
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.
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.
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
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.

I completely understand your frustration, and you’re asking the right questions here. The PD4045KA is lithium compatible, but it does not shut off charging when the battery is full. Instead, it holds a steady lithium voltage around 14.4 to 14.6 volts and relies on the battery’s internal BMS to stop charging. What you’re seeing with the BMS shutting down is actually normal behavior for this type of converter, but it can feel like something is wrong because of that on and off cycling. The first thing I would double check is that the unit is actually set to lithium mode, since that is not controlled from the front panel on this model. You’ll need to turn off AC power, open up the distribution panel, and access the converter board itself. Depending on when it was made, there will either be a small switch or a jumper on the board. If it has a switch, flip it to the lithium setting. If it uses a jumper, you’ll move it over to the pins labeled for lithium. Once that is set correctly, the converter will hold that proper lithium charge voltage. I know the wiring and instructions can feel pretty lacking, and you’re not alone in that. Making sure you have solid connections and proper wire size going straight to the battery can help reduce surging or inconsistent behavior. If you want to send me a photo of the board, I can help you determine if it's lithium mode or not. Happy to help!

After 1 year it is working fine. Love the modern dc fuses, extra dc fuse space, quick charging, and compatibility with Lithium should we decide to go that route.

Hey Kevin, you do not need to run an additional neutral and ground wire when installing with you having the battery on-off switch installed. I am glad it was a great fitment for you as a replacement. What kind of trailer are you installing it on?

Ive been living in the trailer for a year and have not had to do anything since I installed it. Its still working great. Thanks

Still working as advertised. I have not experienced any problems with this converter charger to this point in time.
