We are currently on Octopus Go Intelligent so on a cheap night tariff of 9.5p.
When I bought the system I went for a large battery (2 x 9.5kWh) thinking it is good as we have high use due to Heat pump (but fairly low EV use) and I'd be able to store and export the cheap night electricity when it's warmer and the house requires less.
However I now find that on the Intelligent EV tariff (9.5p cheap night rate) my choices are limited for export, either (1) SEG - useless 4p per kWh or else (2)Outgoing Fixed Lite which is 8.5p so OK for excess solar but still no use for the stored night tariff import. So we are looking into (3) the Outgoing Agile.
It looks like I can set the battery export for the good teatime rate which seems to be mostly 1600 - 1900. The day export (for excess solar) is mostly a bit lower than the fixed 8.5p though.
So I'm wondering if anyone with similar situation has any experience and info to share on this?
