inverter

This 12V inverter, with built-in transfer switch, changes DC output from your RV batteries into AC power and sends it to the electrical system. Using pure sine wave technology, it creates clean power with low distortion, making it safe, efficient, and perfect for sensitive electronics like computers. The inverter can generate 3,600 starting watts and 1,800 running watts which is a great fit for appliances and electronics. Additionally, with the integrated transfer switch, it will automatically change from inverter to shore power when available.


Functions and Features

To connect your AC loads, the inverter includes hardwired input and output terminals. It also has positive and negative DC terminals that connect to your batteries. Lastly, there is a port for the included fixed-mount remote. 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 overloading 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 on the converter, so when the power demand is low, the fan will operate quietly. For additional safety, installing a 200-amp fuse (sold separately) between the battery bank and the inverter will protect your equipment from power surges.


Built-In Transfer Switch Automatically Switches to Shore Power

The integrated transfer switch selects the primary source of 120V AC current. This switch has been pre-wired to automatically change from inverter to shore power to conserve battery life. It includes a 20-amp leg rated at 135V. Additionally, since the switch only accepts one active source, it protects your electrical system from dangerous backfeed that can damage your equipment.


Fixed-Mount Remote Provides Easy Monitoring and Control

inverter remote

The fixed-mount remote lets you monitor and control the inverter from inside your RV. It includes a digital display that shows voltage, output power, error codes, and a low battery indicator. It also has a power button to turn the inverter on and off.


How It Installs

The inverter mounts inside your RV in a dry location with ventilation. It should be installed close to the battery bank, but not in the same compartment.


inverter terminals

The DC terminals are wired to the battery bank.


There are several ways to connect the inverter to your RV's electrical system, but this will depend on your rig and how you want to use your inverter.

Review from a similar Inteli-Power in RV Inverters


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,


Comments
The converter and charger is working very well and I like how I dont have to watch how well the battery is charged

Review from a similar Inteli-Power in RV Inverters


Since I just finished installing this converter late today, I don't have any operational history on which to rate it, thus the Average rating. I do have a couple comments about the product itself. 1.I believe the PD4135K would be ideal for a small travel trailer or a van conversion with few powered features. In my case I have a fully loaded 2002 Roadtrek 190. The OEM supplied documentation listed an Elixer 4500 Converter, however that was substituted or later replaced with a Centurion 3000 Converter which was no longer keeping the RV battery charged. The Centurion unit had 9 usable fused 12VDC circuits while the PD4135K has 7 total and 6 usable for distribution. Compounding this issue was the fact that the Centurion unit had three fused circuits with two separate and different loads connected - a definite No-No for safety's sake. The solution was to install an Auxiliary Fuse Block and feed it from F2 on the PD4135K. The pig tailed leads on the PD4135K were a definite asset in this type of installation. 2. My installation required the use of all three dual 120VAC Breakers (6 circuits) which leaves very little room for wiring within that small compartment. While difficult, it can be done, though I suspect doing so pushes the NEC to the limit. I'll make two suggestions for anyone contemplating such a project. First, consider carefully the number of circuits(both 120 VAC and 12VDC)you need to accommodate without doubling up. It may be worthwhile to purchase a higher amperage rated converter to get the needed circuits and additional room for wiring. Second, mark every wire with a unique number before disconnecting it and record that number along with the circuit's function and fuse rating. Wire markers are available at your local [online]. As well, white adhesive tape and a black marking pen works fine. Doing this may save you time and later frustration. THIS REVIEW AND PICTURES EMAILED!

Review from a similar Inteli-Power in RV Inverters


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 Inverters


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.

Install instructions were easy to follow. Worked perfectly for my airstream renovation. Small size and ability to mount sideways allowed me to put under my front bench seat and not take up valuable closet space.

Review from a similar Inteli-Power in RV Inverters


This power center was easy to install and seems to be working well. However, the wiring diagram on the back of it is small and difficult to read. Maybe I am missing it, but there does not seem to be a buss to connect negative 12v wires to. I think I will have to purchase one separately and install it behind the cabinet the power center is attached to.


Comments
Thank you for your review. I have some installation instructions that should help you. Please note that troubleshooting this electrical unit should be done by a professional. https:www.progressivedyn.comwp-contentuploads201705PD4045-TROUBLESHOOTING.pdf https:www.progressivedyn.comwp-contentuploadsSupportmanuals110145-English.pdf

Review from a similar Inteli-Power in RV Inverters


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.

Review from a similar Inteli-Power in RV Inverters


Cooked my OEM converter on my new 5er due to home electrical install polarity error. Fixed the pedestal but converter is done. Researched replacement models and chose the PD9260C due to good reviews, the 3 prong corded plug (I'm not ready for direct panel wiring yet) and the ability to upgrade to AGM batteries. Received in 3 days. Pros: Very easy to install - basically a drop in replacement. No issues, only extras needed was an 8 ga copper ground jumper wire and oversized wire nut. Started up immediately, battery showing 13.49VDC consistently. Cons: 1) Not packed very well, minimal amount of crumpled paper as padding, no internal packaging box. Shipped by USPS. I have chronic issues with USPS and packages as they refuse to leave at door and (literally) drop them on the ground in front of my mailbox. I was waiting for a quick delivery and got to it right away but a bottom attachment flange was dented - fixed with my Leatherman. I hate USPS. 2) Unit shipped bare - no internal box, no papers included with unit. Is it truly new? Returned and refurbished? Who knows. 3) The link to the installation manual on the product page (not that you need one) has consistently returned a 404 error - you'd think they'd monitor broken links better.


Comments
Thank you for your review and I apologize about the annoying details in your order. Customer Service will be reaching out about the dented flange. As for the instruction link, sometimes the manufacturer changes something on their website without letting us know and the link becomes broken. It is showing up now: https:www.progressivedyn.comwp-contentuploads201705109821F-english.pdf

Review from a similar Inteli-Power in RV Inverters


I’ve ordered from a trailer multiple times. Pretty disappointing when I received a converter worth a few hundred dollars not packaged properly. I’m just hoping that it works so that I don’t have to send it back. But on this occasion it was very surprising/disappointing. Anyways, that’s my two bits!


Comments
I apologize for the state of your package. Please let customer service know if there is anything wrong with it within a 60 day timeframe.

We live in our rv full time and the installation of this power inverter was a great upgrade. I needed one that would charge our lithium batteries while plugged in ana it has worked flawlessly. It is a little smaller then the old outdated one, but was easy to remedy.

Review from a similar Inteli-Power in RV Inverters


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.

I just switched my RV to lithium batteries and needed a new charger. My Progressive charge I purchased from etrailer for my lead acid batteries have been working great so I want to stay with Progressive. Etrailer has the best prices and very fast shipping. I have bought many thing from them and they have been great dealing with.

Working my way to more battery capability. To that end, purchasing this lithium converter enhanced my total recovery time when recharging my battleborn batteries. Etrailer is awesome with all the details and support! Importantly, this converter was the newest version… no offloading old equipment with etrailer… just the best and most up-to-date from this company!

Review from a similar Inteli-Power in RV Inverters


I received my Progressive 9280 converter earlier that originally quoted, which was good. I installed it today and It seems to be working fine. I gave three stars because it came in an etrailer box with paper padding, but no Progressive box, or paperwork. For all I know this might have been someones return before. No way to really tell if it was indeed a new one.
