Appartently 1 week after that the solar panel guys came and said they replaced the inverter and restored the solar panels. Ever since that both cars have been running fine.
This is what the solar panel guys told me. For all i know they swapped out something else casuing the problem. The building manager was off that day so they dont have the recipt from the techs. Again just what I am told.

Thanks, I appreciate the reply. It sounds like the solar array was sending bad (dirty) power down the line. Is there equuipment in the MR from the solar array, or is the interface done in the Main Distribution Panel? Again, thanks for the info.

Quite the back story on this thread. So does the customer now pay the full bill? You guys lost a lot of $$$ on this one and you’ve got the evidence now to support your claim as well.
I’d be interested to know how this gets handled.

This was 2 years ago. But the car was littery just sitting there not running and burnt out the motor. The voltage was 480in/out (maybe a 2 volt diffence from line to line). The soft start was added after the 2nd motor. amps was 000 000 000
