Hi, I have a Victron Easysolar 24/1600/40. I have never been able to get it to work with my generator so I purchased I Mk3 USB interface. I plugged that into the Easysolar unit this morning and it did a software (device firmware) update. Ever since the software update the Red alarm light and the Green and Yellow light are flashing alternately and there is no inverter output. Running the generator makes no difference but the solar charger is working. Any ideas? I've had loads of issues with this thing!!!! :-(
