>From what I understand, they have had the system for a little over a year, and have not done any maintenance on the generator. I was also more suspicious of the generator, and was going to try turning down the charging amps to see if the generator will work better not being so loaded.
Dave, do you know if the Conext will log an error if the relays have actually been damaged? I am hoping that there will be something in the error logs that will help identify whether there is an inverter issue now, or whether the issue lies with the generator input.
