Inverter Problem: Can't Handle Load But.. Should

Are you measuring the wire AND insulation or just the wire itself?

Respond back with the numbers on the insulation and we can tell you the gauge. If it is truly 2/0 then you have some bad connections and or major corrosion going on.

REDD; Just about every truckstop inverter will be modified sine. Most truckers will not pay the price for a true sine inverter (read $1000 or more).

 

Insulation depends on the type of wire. It can be all sorts of thicknesses. Best bet is to write down the info written on the wire itself.

 

There you go. Much too small of a gauge for the inverter. The voltage loss on the wire is what is causing the problem. Upgrade it to 0 gauge for the 10 feet, and you should be fine.

 

And if you are not doing it already, when running the microwave or other heavy short term load, run the engine, and put it up on high idle/PTO. Even doing this you will be able to see the voltage fall on the truck's instrument panel. There is little chance 4 batteries can handle this kind of load with the engine off, and if so you will over draw them, shortening their life, and making the problem worse.

 

i had a 1100w micro in my last volvo running off a road pro 1500 inverter and it would run for about 2-3min with the truck turned off, if i needed it on longer then i would start the truck.

the only thing i had to do when i used the micro was unplug the fridge. learned that one the hard way when i cooked a corbra 1500 when i had the mirco going and the fridge started.

still using that same road pro 4 years later

 

make the dc wire as short as possable and use a good ac cord...
