Measured mains volts this morning at 249V on the inverter display & 247V with my trusty RMS DMM at a nearby power point. Good voltage to let some smoke out of stuff. Brian Are you completely off grid? It's not clear from your post. If you were off grid then there is a simpler solution, using wiseguy's VFB method in your inverter. Today I saw 2KW back charging via GTI, this increased the AC by only 2V. With the original Ozinverter VFB the same back charging would increase the inverter AC 5 times as much. I will have a few free spare PCB's for replacing the original Ozinverter VFB components with wiseguy's method, just need some testing as the boards arrived only today.
