Great questions!I wish AGL would answer these promptly. I am building a new home with 7.2Kw solar panels and 3 phase power (no battery for now). I too want to be able to boost HWS during daytime hours (ideally using solar) but still run off J tariff at night (off peak) so I too am seeking the best way to configure my HWS to achieve this (timers?) Presently my builder is looking at installing a single element 315litre HWS unit.Will share info if I receive any response from AGL. Cheers.
