So, I have been using (for just over a year now) an AIMS Power PWRIX120012S 1200W Pure Sine Inverter with Transfer Switch.
It worked pretty well, but it wasn't my favorite inverter because it did some <horrible things> with the ground floating equally in between the two neutral and hot AC output leads. (I contacted the manufacturer about this, it's normal on that model... dumb design. >:[)
Recently, it bit the dust. No configuration changes, etc. Just a cold morning and the system switched back to solar power (it simply disconnects the AC power incoming and the inverter would normally kick on) and I was greeted with a complete power outage inside and horrible shrill beeeeeeeeeeeep from the inverter.
I checked, the system did NOT over-volt according to my charge controller's logs. The voltage remained below the 15 volt threshold (and above the 10.5 volt minimum) since the inverter was last used 24 hours prior.
I checked the normal things, connections, input voltages, shorts on the output lines... nothing wrong.
So I took it out of the system for now. (Poor panels are now doing nothing with no where for the power to go. :/ ) I've got it on the bench in front of me now and I pulled the bottom cover to check the internal fuses -- They look and test good, so it's not those. I did also check the AC output fuse, it's also fine it.
