I know what was running and what was on standby, so they were easily checked, all are fine. Anything on standby would have gone up in smoke if a standby circuit had shorted.

That power level is unheard of in this system, the maximum load I can reach is around 9kW. The logging sensors are independent of the Inverter, when the Inverter C63A AC breaker was switched back on the first time, the DC current input to the Inverter kissed 800A.

I believe the fault was coming from the Shed AC circuit, this has two external weather proof power points with a Big water Pressure Pump from the Tanks and a Hot water System, both were checked and everything was dry, and both work correctly.

The washing machine was running on heat cycle, I turned that off before the first attempt at Mains along with the Pump and W-Heater which had been running, and it still blew the AC breaker.

The power was an additional 11kW above the max normal load for that time.

We will see how it goes overnight - I'm calling it a day and heading over to watch a movie.

Thanks again for the input. I will go through everything in the Workshop tomorrow just to be sure.

BTW the Shed circuit from the main Fuse box is extremely heavy cabling as it needs to start and run a number of large workshop Induction Motors on top of the normal workshop high running loads, which it does easily with very little voltage sag.
