Hello,
Our inverter was connected to a couple of PC, phones and a modem like allways but it failed and shuted down somehow, now if I turn on the inverter it will drop the battery voltage from 25 to 10V at 0W and show the blinking red light without green after completely disconnect, after turned completly off the battery voltage will raise again. What could be wrong with the inverter? I suspect that there was some backfeed from a microinverter that we keep connected, althought it has been running for years in parallel with the inverter... another clue is that some phone guys came in yesterday and changed the phones and the modem. I would like to repair the inverter but what should I be looking at in the inside of it? a shorted capacitor maybe?
