If you have never re-booted your inverter since getting .34 firmware, then please do so. We found today that it might be causing the issue of the system failing right as the truck begins to deliver power. You have to turn off the dark start battery after turning off the inverter breaker to get it to reboot completly.I did see this when you originally replied with it and appriciate your technical assistance. I apologize for not responding directly to it at that time, but I don't think any of these items are the culprit.
I most always test when no one is home and no major appliances are running. The AC system isn't backed up, and the heat won't start immediately due to the thermostat's slow reboot process. The only large load on the backup panel that will randomly turn on would be my well pump and that shouldn't be coming on every time I test. One thing I have not done is try a no-load pickup, that would rule out this potential issue. If this were to happen would the low voltage fault happen before any load is picked up? My system faults out without any power transfer having started.
Yes, it has worked in the past and nothing has been re-wired since.
I have always tested by simply shutting off the main breaker in my original breaker panel. When the system was working this is how i confirmed it. (it never has actually auto-transferred in a utility outage)
Few days ago my inverter was at rev .34
looking at the FCSP setup app (i dont see version info in fordpass anymore)
Software version 2.112.91:2.149:1.32:0.62:1.53, Firmware 5.0.16 this seems much older than leejimerson's 2.112.125.xxx
