HI Coulomb,
Thanks for the reply
I have been monitoring his now for a week after, This definitely only happened when we were in a heatwave. Since then, outside temperatures have been cooler and no more errors.
However, i was wondering if the CAN error is actually caused by raspberry Pi that is getting "too hot" instead of the invertors, I only assume this as the error is a communication error and not overheating or something to that fact?
Regards
