I think that a lot of these 12v units are made for car batteries.
So, they set the OVP/shut-off at a voltage that's hardly ever seen on a car..
Maybe when they started doing 24, 36 & 48 volt chargers, they just multiplied x 12..?.

I wonder if you could put 6 or 8 diodes in series with your Inverter, to drop it's supply input a bit?? Have to be hefty ones..

My guess is, a very small percentage of the 12V inverters sold are ever used in a PV system.

I have a bunch of stuff on the bench now. Most of it deals with making hot water..
It's going to be a long time before I get to the soldering iron again.

My Solar stuff is working right now, so I'm not going to mess with it.
Just need to repair one blown inverter..
