Storing excess power in batteries is no solution.
Just today I looked into some LiFePo4 batteries; one unit, 12.8V by 40 Ah including BMS looked promising. Could store half a kWh. Could have 2000 charge cycles. Did cost more than 1.000 kWh would cost, and thats without the DC/AC conversion.
So there you have it; storing energy is good for power outages, but not for saving on total cost.
You can try to match your demand to your production, by having twin thermostat settings on your boiler or fridge, to make them work harder when you have an overage.
Or a smart use mode for the home A/C. Could be a nice Arduino project balancing them all. Well you get the idea.
