Exactly. That seems logical. In fact, it's true that the controller (and AVR?) DO have DC power during utility outage. The controller responds normally to any keyboard input, just as you'd expect. So obviously, there's a DC connection somewhere in there. However, it's also true that with the charger unpowered, the startup sequence fails, emitting the 1062 error. And as I'd mentioned earlier, both the controller and AVR were replaced without any change. That's why I suspect wiring: a missing wire, incorrect connector assembly, or a damaged pin. I may just rip the whole thing apart when weather permits next spring to buzz out every connection and inspect every pin & socket.

Yea, something is definitely not right there. These units operate completely stand alone off of the 12V system. They will run until the battery dies basically...

I'm having the same problem with my Generac Synergy 7040. Could you tell me what you used for your small UPS on the T1 connection and if you have found a way to force the clearing of the 1062 error message vs letting it timeout? Thank you.

I have this same problem with my model 7040, although I don't have as high a failure rate. When my new unit (Dec 2017) started having error code 1062 failures, it was fairly infrequent, and usually not at startup. So the installer, at the direction of Generac, added ground wires within the unit to the various modules (cabinet grounding, I don't believe any grounding was added directly to a circuit board). That improve reliability for about 18 months (I'd have to check the log, but maybe had 3 failures in that time). But now my failures (about 30% of the loss of utility power starts) occur at startup, and cannot be cleared for a couple hours. I need to take a video of the failure - when I try to clear the error I think the panel says something about stopping the unit... while it makes a clicking sound for a few seconds, then returns to the alarm state. It is interesting that I also see heavy 'flickering' of my lights that are on electronic switches (I use Insteon home automation devices). That flickering is really bad at startup and lessens as the unit runs over the course of about an hour, but never goes away completely. I don't have a scope to put on it, but I wish I could see the sine wave coming out of this machine.

Now that I'm out of warranty, I get a bill for them to come out and look at the unit and say, it starts now, there is nothing more we can do. I am going to show them this thread in the hopes that this information, coupled with the technical documentation they have access to, will allow them to find a solution. Unfortunately I have limped through the warranty period, so we'll see how Generac will handle this next step. If they won't cover it, I'm not even going to start the service fee meter running. I'll call a Kohler dealer and work on getting this replaced. Hopefully I could re-use the transfer switch and remote load shed devices.
