This might be a stupid question and I think I already know the answer but I wanted to make sure. I have this power inverter and It immediately trips as soon as I turn it on. My question is should I have continouity from neutral to hot. Of course no batteries are hooked up when I do this test. As it stands now I do have continuity. I shot line voltage through it one night on accident when i was testing something and think that contacts inside arced together and maybe causing my overload. Any thoughts?
So now the batteries are installed and nothing is plugged into the output (120 volt receptacles) and the inverter trips when you flip its power switch on?
From what you told us, I think the inverter is fried. History.
The normal and also easy checking of an inverter is done by measuring volts (between hot and neutral) at the output. Plugging in a small light also does the trick. When your inverter tripped immediately, the preceding test is deemed to have failed.
Turn off power before doing continuity tests. With an inverter, where to do continuity checks and how to interpret the results (and also find out exactly what got fried) requires a good amount of electrical know-how.
