I have been interested in plug in batteries instead. I could do it for my own house but not sure about the solar as well. Probably run my house off the battery and plug the mains into the battery to top it up.
Jackery, ecoflow and a few others all make pretty large multi kWh batteries. Seen some that are 20+ kWh. Not sure how much solar input they take, pretty sure some can do a few kW solar input too.
Then it is a matter of fitting the solar panels though. If my garden was larger it would probably be better, not sure on fitting them to the roof myself. In summer I could probably get quite a bit from my garden but winter its mostly in the shade.
Might be worth analysing my energy usage more. Heat pump would require an electrician and a proper house battery, not really a DIY job. Everything else could be DIY. My summer usage is like 150kW a month and that still includes hot water on the heat pump. So I presume I could do everything else on a fairly small battery and solar panels.
Alternatively, no battery and get rooftop solar and just sell the extra energy to the grid to pay for my energy usage when there isn't enough solar.
