I had a new installation of solar panels and battery in August, so still finding my way to the how to get the best of them.
I'm on Agile Octopus with Fixed Price Export and set those up in the Cloud Portal with the tariff automation setting on solar+battery.
Overall this has worked fairly well but it does not get the best out of the occasional 'price plunges', when the unit rate goes negative and so you are paid for the electricity you use. I would have expected the automation to ensure that at these times the battery would be charging to maximum and any home usage fed from the grid but this does not happen! The first price plunge I tried to make use of I was happily making use of as much electricity as I could, only to find that it had all come from the battery, which then recharged from the grid later when the price was positive, although low. So I gained nothing at all from the price plunge.
I have since found out what manual inverter settings I need to do to get the desired result, but they often get overwritten by the automation before the price plunges, which are usually in the wee small hours and so I don't get the chance to reset.
How do I find out whether the automation coding is likely to change or do I need to continue to manage it manually?
Thank you.
