Power inverter that runs the refrigerator

Power inverter 800 watt that runs the refrigerator while i'm traveling. It works great for about a 100 miles then it stops working. I have better luck if I turn the refrigerator for a couple of day. I wondering if it the inverter or my alternator or need another battery.

Perhaps it's turning off because the battery driving it is becoming discharged. Either your tow vehicle isn't providing power to the RV while towing, or it's not providing the 40+ amps that would be required for 500 watts at 12v.

Yes, there is no way a tow vehicle alternator will replace that much power consumption from the trailer battery.

Thinking about taking it to the dealer they installed the inverter and wired it up.

Is this a residential fridge (eg, only works on 120v)? Doesn't it have the ability to run
on propane while you're traveling? That's what most of us do.

I would use a meter and check pin 4 on your TV to make sure your vehicle is putting out 12 volts and charging your batteries when running. Sounds like it is possibly not putting out any charge line.

Well, if it is 110 only, you are kinda stuck.

1) pack it with ice in ziplock bags so the heater does not run as often and the water does not run all over the place

2) More batteries (deep discharge) not dual purpose (or starting batteries). The POS one that you have now is most likely 60 AH or less. A pair of 100 AH batteries would do the trick.

Trojan Battery Company

3) Solar panels on the roof to assist keeping the battery bank up.
