Look at the circuit breaker and fuse connections especially.

exactly, as this is what I told Magnum - I 'normally' see a 'FAULT' and some explanation or Fault Code wording - but in these situations I'm not seeing any other than
'OFF' and the current DC Volts reading, just as if someone reached up to the panel and pressed OFF.
This leads me to believe that it is losing all 12v power, even for just an instance, which cuts it to OFF mode.j
Batteries? Possible. I will check the voltage readings for each, and also the tightness of the connections, and possibly try to read the volts WHEN I apply the large load on the inverter and it cuts off. We'll see.
