I have an E.ON Solar tariff that means I can buy electricity at 6.9p between 00:00 and 07:00, and export anytime at 40p.
I have my setup such that the battery will export for 4 hours leading up to midnight and then recharge at the 6.9p rate.
This seems like a good idea to me but it's such a simple way to make money that I feel like I'm missing something. Is there a downside of doing this or something I've missed?
Thanks
