We have just received an enormous power bill and when I checked my usage graph, I realised that our PV system had failed 3 months ago. Our EV charging, daytime air con and hot water heater have all run off our solar array previously. Coincidently, our PV failed on the exact first day of the new billing cycle, and I do not like these coincidences.I see that our AGL page has had a warning that there was a PV fault, but I only go to that page when checking consumption or a bill. Is there any reason ...
