Inverter damage from High input voltage?

MikeRuth · Mar 17, 2015

that's one stout DIODE, But I concur dropping the voltage via a diode is not the way to go, and after today's tests that diode would now be a closed circuit

I conducted a little stress test on the system and pushed the inverter to about 90% and the draw was 122 amps.

I'm just going to have to make sure that before engaging the inverter the voltage is at or below 15.0. If I crank up my Vent Fan it will knock down the voltage in a minute or so, and if I'm using something stout on the inverter I can always just turn the fan off after a couple minutes. As for the equalization charge being automatic, it is no longer. I'll do that if and when I see SG readings that indicate it or once a month or so when I know the inverter will not be used.
Right now the only other concern I have is the Audio Amps. I have to look up the specs and see what they are. I haven't switched them to the house battery yet.

Otherwise there isn't much else tied directly to the house battery that the high voltage would be of concern.

Hey this one would work for me, LOL
200 Amps.

I don't know what your problem could be.I like to keep things simple. I use pulse wave controllers and a Harbor freight inverter.When the system overloads,the inverter shuts down.I must be doing something right,I've used this sytem for 6 years and my 12 GC batteries are still going strong.

Wow, 12 GC batteries! That's the most I've ever heard of. Makes my 6 look kinda pathetic!

We need them all,Bob.We run an 18 cf self defrost ref,clothes washer,dish washer,two tvs,satelite system and all lights.This is only possible because all the appliances are energy star rated.When we hit the road,we borrow 3 panels to mount on the camper.
