Hi all.
Very much still learning here so bear with me !
My batts are set to force charge from the grid from 2 - 5 . After a broken night's sleep last night I was up at this time so thought I'd check out what was going on.
My batteries are full by around 3.45 am but when I looked at the system on the app we were still pulling power from the grid to power the house after the batteries were full. I presumed , once full the house would take power from the batteries , not from the grid. After seeing the batteries full by 3.45 I was considering using the force charge from 2 - 3.45 but am now wondering if it's just better to keep to 2 - 5 using the cheap tariff. It's now 8.45 and one batt is at 68% and one is at 86 %. All advice greatly appreciated .

You should keep the system at 100% SoC for the duration of the cheap period, once this ends, you can then allow the batteries to flow, saving you from buying the more expensive electric at peak rate.

OK thanks MB

You're welcome, this is how I would do it myself. I think I average about 20p/30p max of peak electric per day (have and electric shower, so the excess comes from grid that is needed)
