[QUOTE="Slateral, post: 538298, member: 34849"] Related issue for me. I have a 5.8 kWp PV array and a 6kW battery storage. Currently on Octopus Agile Export and Variable Rate Import. I'm getting a PHEV in January - 18.1kWh battery and will install a Zappi to charge it. Hot water is gas boiler heated immersion tank in airing cupbboard and is only on for 1 hour a day to provide hot water for my wife and I, so not a high demand. I'm wondering if it's worth installing Harvi and Eddi at the same time as the Zappi - product info on website talks about ability to use Eddi to dictate battery charging times, but how would that interface with my Solis inverter that currently controls charge/discharge of batteries? Also, I am considering installing aircon in 2 rooms in 2023 and understand that Eddi can divert solar generated energy to power them - which sounds a good idea, (although I get a good return on Octopus Agile in the summer months ) I'm assuming that if I go ahead with the A/C install then Eddi makes sense, but if no A/C then probably not? I'd welcome comments/advice (Apologies if I'm hijacking a thread here - not my intention, but a rebuff is welcome if I am :unsure: ) [COLOR=rgb(147, 101, 184)]Split from hi-jacked post, to avoid confusion for OP[/COLOR] [/QUOTE]
