@Rugbyleague I’m no expert but the way I run my system is all solar is sold back to the grid. I charge my 48kwh batteries at night on cheap rate and sell any energy left in the batteries back to the grid @ 15p. I never charge my batteries with solar as it’s cheaper to fully charge them at night. Most UK houses use less than 10kw of energy to run a house so your battery should have spare electricity to sell back to the grid at a profit, but at 7p and sell at 15. when you are selling your energy, solar or battery, back to the grid you can’t import any additional free slots of cheap energy without the faff of setting your solar to fill the battery and stopping your battery selling to the grid. So most people in our situation don’t get the additional cheap slots during the day. Home Assistant however can do this for you, so I’m told, and that why I’m looking to get it installed so I don’t need to mess about with my system. I hope that makes sense 🤞 lol
Ahhh got it now and absolutely understand……yes I hadn’t thought of that.
There will be a way of informing the battery of cheap electricity being supplied through a code. Off to find out…..
