Stuart1 Great so all 3 slots are now working. But can it be set within the slots to just charge the battery and when at set charge level it will stop charging and importing instead of importing for the full 3 hour slot. When I do it on the shine app slot 1 charge for 2 hours slot 2 charge for 1 hour and slot 3 charge for half an hour and that kept it topped up and running my heat pump all the time (24H). Is this possible ? Please advise.
