Question about RoadPro AC/DC Power Inverter 2000/5000w

2 Answers

I have a 2500 watt roadpro, and would like to no if there is a different way to hook up to keep from killing both of my batteries in my Dodge Cummins. I have a small freezer that I take hunting so I can cool the meat, and freeze the capes.

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 can install a battery isolator or battery switch between your two batteries; using one for the inverter and one for the truck. Or you have to get larger capacity batteries.

If you are running any extra systems, ie amps, subs, high watt speakers, etc. etc. you may need to get a better batter, like the blue. or yellow top one. check with auto zone.

Have several non working inverters

I have had this happen a few times.

Sadly replacement is the Best option.
Repairs can be %75 the cost of a new one.

The best invert we have been using is a Pure Sine 1500 watt inverter.

Sad news but hope this tip helps.

I just bought a RoadPro 2500 and i want to buy like a dorm fridge how many watts or volts size would work??

If you are referring to the RoadPro RPPI-250
  • 2000 Watts Continuous Power
  • 2500 Watts Power Output @ 10 Minutes
  • 5000 Watts Peak Power Output.
  • A small fridge will use about 500 -700 watts, with startup wattage at around 2000watts.
  • So, a dorm fridge will work fine.
  • the RoadPro converts DC to AC voltage, so a regular 120 volt dorm fridge will work.

    I want to be sure i don't run down my battery or ignition units from my alternator for a 2500 watt stereo amplifier, to maintain good performance

    You wont necessarily run down your battery by using this 2500 watt amp. As long as your alternator is good it will keep your juices flowing through your car.

    I have no instalation instructions for my 2500 rppipower inverter

    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.
