Yes agile slots.
WW sent an instruction @ 21:29 to charge from 21:30 to 02:00.
The inverter logs show the same but at 21:30 the battery went idle and didn’t charge.
I tried manually changing the start time on my inverter and it still wouldn’t charge.
It only did a timed charge once it had gone past midnight.
I have been looking through my inverter trends and once it didn’t charge as asked from 21:00 till 04:00 it’s just sat there on idle.
Looks like a GivEnergy issue to me.
