20 Most Recent RoadPro AC/DC Power Inverter 2000/5000w Questions & Answers

Refrigerators require a LOT of power. They are one of the biggest energy consumers in a typical household. Although they don't run all the time, they kick off and on quite a bit. To answer your question, there is no wiring solution for your problem. Power inverters are inherently inefficient as well therefore they are actually pulling more power than required to power your refrigerator. Your refrigerators will work while your engine is running (because the alternator is providing continuous power) but as soon as your engine is off, they switch to battery power. If an generator is out of the question, I'm sure you can find larger batteries that could extend the time your refrigerators can run.
I hope this helps!

You should use 2 red and 2 black cables, Install the inverter as close to the batteries as possible and use minimum #4ga cables #2 are better. Keep the cables as short as possible. You will need also connectors, like the ones on the truck's battery cables, attach these to both ends of each cable and crimp VERY well, connect all 4 cables to the inverter first, then the red cables at the positive battery terminals (if 4 batteries use one on each end) then the black cables to the negative posts the same way.

Have you checked the fuses ?

Make sure the ground from inverter to frame is intact. Make sure the positive and negative connections are clean and tight. If this all checks out, disconnect power to the unit for 1 hour and let is reset. If it still shows a fault then you really need to send it back to the manufacture for repair.

Check the Following:

1. Ground from inverter to frame is intact
2. Positive leads are intact and clean
3. Negative leads are intact and clean.

I hope this of help to you please rate if the answer is of any help. If I can help any further will be glad to. Good Luck and have a great weekend.

check if the fuses are broken the replace them with the correct type, and check if the is any burnt part

Sadly replacement is the best option. It is just not cost effective to get the inverter repaired.

The cost starts out about 150.00.

Best option is to take it back to where you purchased it and hope you can get a new one.

Hope this tip helps.

Am a seven each power inverters owner.

Recommendations: Purchase a Pure sine inverter 1500 watt. We have had one of these running 24 seven for almost a year now.

2500 gives no power and fault light comes on?

Thirty amp should be fine.

maybe the fuse is bad......... the one i have has a fuse dont know if that one does

there is no manual reset switch just unhook it from the power supply to reset it

I have had this same problem with several power inverters over time. The problem is usually one of three things.

Those starting with the simplest.

1. Too much current being drawn on the inverter.
Solution (Check appliances that are plugged in and make sure they are not drawing more than 1200 watts. If they are unplug the appliance that is using the most current and get an inverter that is more suited to your power needs.)

2. Some power inverters have fuses built on to them. Sometimes multiple fuses. Sometimes, one fuse may burn out leaving one intact. When this happens even small items draw too much current and over load the inverter.
Solution (Replace the fuses)

3. Improper installation. Inverters draw a lot of current. You must use the propper wire size for the inverter. I would recomend at least an eight guage wire directly fused and hooked directly to the battery. Of course like with all things the bigger the wire the better the flow of electricity.

If it is not one of those things stop into a truck stop electronics shop and have the person diagnose it.

Hope that helps.

I C this post is dated April, so maybe OP has solved problem. Most likely a stuck simmerstat (controller) which needs renewal.

eBay is your best choice for these items.

Did you ever find an answer to fix your problem? I have the same type of problem, and feel bad as I am an electronics tech with years of experience. I know that it must be a bad IC, transistor, capacitor, diode, resistor, etc. However, with all the components in the 2500, it is almost impossible to trace it out without a "Service Manual" or a schematic diagram. To blindly go in to just start 'tracing' a circuit and not knowing the wiring is not good to do. It is also almost an impossible task to simply start removing parts to test on the bench, and then reinstall. Even IF all test good, there can be a fault on the board itself. For an answer you can do as I am doing, and that is to call the company that is listed as the company involved with customer service.
