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.

Video Transcript for Progressive Dynamics RV Converters PD924024A Review

Today we're going to take a look at the progressive dynamics PD90, 200 series, 24 volt, 40 amp, Inteli-Power converter charger.This power converter charger will deliver DC power to and it will also charge 24 volt batteries for specialty vehicles and stationery applications. This is designed, it's perfect for buses, local refrigerated delivery trucks, emergency vehicles, communication trucks, over the road trucks with sleeper cabs, and even solar energy.It has a built-in charge wizard, which is a four stage charging system. It'll constantly monitor your batteries and it automatically adjusts your converter output voltage based on the battery's charge status. The converter charger is capable of charging multiple batteries at the same time and it can also charge different capacity batteries at one time.It has many builtin features to ensure long term reliability. It has electronic current limiting, which will automatically reduce the output voltage to prevent overheating. It has reverse battery protection, prevents the charger from getting any damage if your connections are accidentally reversed.

It has high voltage and low voltage protections to prevent damage from AC input voltage fluctuations. It offers automatic thermal protection, protects from damage due to excessive heat. And right over here, you can see they do offer a variable speed intelligent cooling fan, and this will only operate under high heat conditions.It is GFCI protected, helps prevent ground fault interruption. This part is assembled in the U.S.A. A few specs on it.

The input voltage is 105 to 130 volts AC. Wattage on it is 1300 watts. Output voltage is 27.2 volts DC. Power drawn out is 40 amps.I just want to give you a few dimensions on this. Overall length on it, we're going to measure from this end right to this end, so you're going to be right at nine and one-eighths inches long.

The width on it is going to be right at seven and three-eighths inches wide. And the total height on it is going to be right at three and five eighths inches tall. The power cord on it is about 30 inches long. And overall weight on this unit is about 6 pounds.That should do it for the review on the Progressive Dynamics PD90, 200 series, 24 volt, 40 amp, Inteli-Power converter charger.

Review from a similar Inteli-Power in RV Converters


Works as advertised. I can charge two 100 AH LiFePo-4 batteries with no trouble at all. Just make sure you use decent gauge wire because this charger is a beast! Smaller gauged wire will heat up due to the amount of current this thing delivers. It does constant current charging and then switches to constant voltage to top off the battery. Well worth the money!

Review from a similar Inteli-Power in RV Converters


Worked perfect with my four 100 AH Lithium batteries.... Stock Winnebago charger was a weak 30 amps @ 13.2 V.....this baby delivers 80 amps @ 14.4 V. which reduces generator runtime on cloudy days when the roof solar is not producing. Had to change the 15 amp RV panel breaker to 20 amps...no big deal...I'm happy with this purchase.

Review from a similar Inteli-Power in RV Converters


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.

The Progressive Dynamic 80 amp lithium charger is a great product. Charges the lithium batteries very fast. Its a simple well built charger converter. I've used it for about 8 months now. I used to own a 40 amp Progressive Dynamic regular battery charger converter on my previous rv. It worked great for the 12 or so years I owned it.

Review from a similar Inteli-Power in RV Converters


This product was recommended by the lifepo4 battery manufacturer to fully charge the 3 batteries I purchased. Installation was pretty simple. Did not have to run larger wiring which was thankful. Simply swap out old converter charger with new one and ready to use. I would highly recommend this product.

I have had no problems whatsoever. Boondocked for 9 days in Grand Teton National Park last September. Used my generator to freshen up Battle Born lithium batteries and converter charger worked perfectly.

Review from a similar Inteli-Power in RV Converters


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,

Review from a similar Inteli-Power in RV Converters


The service from eTrailer was excellent as always and customer support was very good. I was replacing my brand new WFCO WF-8735 unit because it was not a smart charger - I could not get it to charge my batteries at full speed. The PD4135 is a direct replacement for it and provides better options for charging manually and also has a switch that converts charging for a Li battery. Although the product installed easily, there were a few glitches. One, etrailer did not send a manual with the product, so I had to get it online. Even then, the manual left a lot to be desired. It didn't describe the installation well nor the operation. The PD unit is a bit smaller than the WFCO and therefore the PD cover just barely covered the old screw holes. Also, the WFCO has 7 fuses but are not identical to PD's 7. The PD has 5 branch circuits like the WFCO except it has one extra circuit that can handle up to 30A - that's the second red wire (labeled 002) and the 6th fuse. The 7th fuse is red on both units and is for reverse protection. The 6th fuse on the WFCO is to doubly protect all of the branch circuits and has a metal 30A fuse - that's not in the design of the PD. Operationally, the PD works fine. The switch to convert to Li batteries is TINY and prone to breaking off (my first unit had the the switch in the bottom of the box!) You'll have to scour the PD website to find a picture of the switch since it is not included in the manual. Also, not included anywhere is the need to remove a 4 wire harness when using Li batteries. Also hard to find but on the website is the operation of the push button for manually exiting the Wizard mode and the meaning of the flashing light. Other than those minor issues, the unit is great.

Review from a similar Inteli-Power in RV Converters


This converter was an awesome upgrade to our RV. Our stock converter just didn't have the oomph to get out lithium batteries full. The Progressive Dynamics Inteli-Power RV Converter and Battery Charger - Lithium - 12V - 80 Amp has done the trick. It was a simple upgrade even though it was in a very tight area.

Review from a similar Inteli-Power in RV Converters


Good converter, good company. Use to charge a lifepo4 battery. Wish there was documentation from the company explaining how exactly the charger charges the batteries; graphs of the rate of charge, voltage, etc over time and over the total charge capacity. But that would be asking a lot. The product is excellent quality.

Just received it but reviews are great and it is exactly as described. Will be perfect for my old 13 foot Burro trailer. Can switch between Lead-Acid and Lithium batteries so is future proof. Sales/shipping experience with etrailer was great of course. Literally shipped an hour after order was placed. Shipped to Canada in ~4 days. Outstanding all around.

Ask the Experts about this Progressive Dynamics RV Converters

  • Charging Two 12V Lithium Batteries Properly
    Whenever changing the battery type, it's a smart to change the way you charge. I would recommend getting a 12V Lithium charging system if your batteries are not wired in parallel. They most likely are so in that case you should get this one # PD924024A. It is the same brand as your other one # PD9160ALV but is for lithium batteries.

  • Are Progressive Dynamics Converters Compatible with Flooded Lead-Acid Batteries
    I believe by FLA you mean "Flooded Lead-Acid" battery bank. Since this is just the standard battery yes, the Progressive Dynamics PD9200 Series Inteli-Power Converter Charger # PD924024A as long as they are connected as a 24V system. If they are setup as a 12V system then the equivalent at 40 amps is part # PD9140A instead. Attached are review videos for you to check out.

  • How to Provide 12V Power Source for Testing Trailer Lighting
    I spoke to my contact at Progressive Dynamics and he agreed with my proposed recommendation that for your specific application of temporarily testing/evaluating light placement in your build project you simply use a 12V deep cycle battery along with a solar battery charger like # PTW2997. This 2.5 watt solar charger has built in blocking circuitry to prevent reverse discharge from your battery back to the panel. This also means you could use two chargers at once (in parallel with the battery)...

  • Inverter and Smart Battery Charger for RV with Smart Batteries
    Since you have smart batteries which are designed to communicate with smart battery chargers your better option is the Progressive Dynamics Inteli-Power RV Converter and Smart Battery Charger # PD924024A as it's designed for smart batteries. Then for cables to connect the battery bank you'd want the part # DW04362 for the positives and the # DW04365 for negative. The Renogy 200 watt solar suitcase you have will do a great job keeping the batteries topped off and will minimize battery...
