converter charger

This smart converter charger converts AC shore power into DC power and uses the Charge Wizard 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.

Charge Wizard Operation

Using the built-in 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

cooling fan

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. It also has GFCI protection that shuts off power when there is a current imbalance. The built-in cooling fan also removes excess heat from the unit. The fan speed is proportional to the internal temperature on the converter, so when the power demand is low, the fan will operate quietly.

Available Converter Status Remote Pendant for Easy Monitoring and Control

converter status remote pendant

The Converter Status Remote Pendant (sold separately) monitors the converter's charging status. It also allows you to manually override the charge process to verify the unit is operating properly. The pendant uses a flashing green LED to indicate what charging mode is active. It easily connects to the converter's accessory port with the attached cable.

How It Installs

The converter mounts horizontally inside your RV in a dry location with ventilation. However, as long as the unit has sufficient ventilation, it can also be mounted vertically. The mounting hardware is not included.

terminals and plug

The DC output terminals wire to the battery bank. The AC in cord plugs into a 120V 3-wire grounded source.

When my 40-amp converter suddenly quit working, I began searching for a replacement after confirming with my multimeter that there was no output. I found very few 40-amp and those were very $$$. I contacted to see if I could replace with a 45-amp. A quick response assured me it would assuming the 12v wiring would be heavy enough since an additional 5-amps would be minimal. The installation was very simple, and the system was immediately restored.
THANKS, etrailer!!


Easy to install and served me well for the past year - almost. Recently it will not charge my battery and I find that both 30A DC fuses are open and I do not know why. The result is no output voltage, of course. Will be calling about this.


This is a good replacement for WFCO that came with the Motorhome. While the WFCO will deliver at least 20 amps of current it is only at 13.6 volts which isn't high enough for Deep Cycle batteries. The PD9245C will produce the same current at 14.4 volts which is the minimum you want for Deep Cycle batteries. Since there is a slight draw always on the house batteries the PD9245C stays at 13.6 volts when batteries are fully charged. Exactly the float voltage required by Interstate AGM batteries.


This was a great deal and just what I needed to replace my old converter. It was worked flawlessly ever since I installed it.


So far so good! As I’m familiar with these products, I’ve known them to be very reliable. My order was received undamaged in a timely matter. Great service!


Great replacement of a smaller converte r.


I use this along with two 6V golf cart batteries and it works great for dry camping. We run the generator about an hour a day and keeps them charged. Did a few trips this summer for a week at a time with no issues.

Still working good

Thank you on posting questions and answers it really helped us replace a compatible converter. Your response time was great along with delivery time. My husband already installed and closed everything up so I didn’t get photos.


Exact duplicate for existing part. Ask me again in 6 years to see if it lasts longer than its predecessor.


upgraded replacement for the original p art.


After I removed my old unit I installed an outlet then slid the new converter into place and wired it to the connections on the fuse board.After plugging it in the fan came on momentarily. I checked the voltage and it was at 13.59.The unit is compact, quiet.I used this unit to replace the Parallax 8345 converter.


Quick delivery, purchased as spare.


Excellent staff very helpful shipping was a little slow


Straight drop-in (okay a couple weird-angled semi-difficult to reach screws) replacement for a 10 year old PD 40 amp model that had developed a high pitched whine. Works great. Blissfully quiet now.


Very satisfied. Installed in a small vintage camper and keeps our single battery charged for 12V lighting.


it replaced a converter in a 1991 RV. it works fine.
On the old converter there was a blue wirer that I didn't know where
it went. Because I could not get 12v to the 12v fuse block. with a ohm meter I found it to be the feed line thank you for your service.


Awesome unit, easy to install. Solved my issue perfectly.


Order was correct and arrived in the day indicated


I recently found out that for the last year my battery has been dead on my RV. I live full time in my RV and I did not notice the dead battery because this charger was so good, it never missed a beat.


Great service,item is working as descri bed.




Excellent product. Easy install.


Fast delivery


Its very unusual to see ordered product arrive when promised, especially here in Alaska. Typically 2nd day means 5 to 6 days later. This isnt the first time etrailer has come through. Not only satisfied but impressed.


Easy install, quiet and effective. Would buy again.
