Version 8.1 uploaded. Version now appears in the Sig below.
EDIT: For anyone wondering about that 50ms delay before halting SPWM and requesting an Inverter restart.
The Code now reads the Delta voltage 5 times. Once each complete code run cycle, which is every 10ms. If the voltage difference is still there on each run for a total of 5 passes (50ms) it will trip, otherwise it was a "once in a blue Moon event" or an act of Murphy, and can safely be ignored.
Worth remembering, this Inverter had never tripped a "Delta Error" before, even under daily multiple 25kw surges and even a Mains short circuit and it's running 24/7.
