I attached several pictures and the solar panels specs are upside down. Sorry for that. All the connections are soldered and heat shrink. I tried my best to do everything right. Panels are connected in parallel.

I believe I know why I am killing grid tie inverters. I live on a main road, main line. I get power spikes and power outages and when the power comes back on I get power spikes. Do anyone know of a protector that will safe guard when the power comes back on to stop the surge or trip off when I...

I don't know. My last inverter was a dc 11-18v to 12 volt ac unit. I have used from the cheap amazon to the expensive units. I don't get it! all my connections are soldered and grounded!
