Home Battery revisited

 After a full year of operation, time for a checkup.

The App that displays data has been updating and improving.

My spreadsheet says the battery is saving me about £840/year. That means the return on my investment is around 20%. This was much better than I expected! Since batteries last around 10 years, this investment was successful.

Purple line - battery charge. Green - battery. Blue - Grid input. Orange - electricity used.
