So forget the battery as I’ll be home during the day that’s when you do all your washing etc to just draw from the panels, also charge your car? Then at night it’s just grid stuff for the tv and lighting.
Next question is even in the depths of winter how do they cope with snow and very dark days, would they generate enough to get any benefit (I know some is better than nothing)
in regards inverter and battery I would hope in 10 years that cost might have come down, didn’t know about the battery cost I heard £3k so I’ll have to do more research.
