EASUN iSolar SMR II Inverter 5.5KW ( SOROTEC / REVO-WM II 5.5KW )
I keep blowing up inverters when connecting them to a generator....
I am off-grid... when the inverters are running off batteries and solar panels they are fine, but after 3 or 4 days of rain the batteries are empty. So I connect the generator to the AC in on the inverter, it runs for 30 minutes or so charing up the batteries and some of then the inverter blows ( ICs in the inverters start blowing )... I have blown 3 inverters so far.... getting expensive.
Any knowledge on what might be happenign would be most welcome.
