[QUOTE="MHarv, post: 539209, member: 34994"] To keep your Fit, you are looking for AC coupled battery system great in the summer but for winter if not on TOU Tariff ie Octopus Go tariff 4 hours off peak to charge batteries will be hard to use effectively if at all, only at a standard tariff at peak price not cost effective. Depends also if you have smart meter for 30 min readings working and connected to your energy provider for TOU tariffs are really required to utilise TOU tariff for the winter period. Which was my case, smart meter change over to Octopus energy then as I purchased EV moved to their Octopus Go for off peak energy rate, SolarPV install G98 and last October 2022 decided to go batteries G99 Fast Track using Solax X1 AC 3.6kW inverter with Solax Master Battery With BMS V2 LFP and one Solax Slave V2 LFP Battery total 11.6kW to 5 bed Large Detached house double garage for solar Pv and batteries. Only paying now £1.45 daily for 10 - 11 kW Using Octopus Watch and Octopus Compare from between £3.65 to £5.00 so a big saving. To be honest with electric prices going up will not be coming down soon in the future, theirs a very tricky alignment to now happen in Europe reference our RED. [/QUOTE]
