I can't restrict the discharge time of the battery at the moment, it was working fine a few days ago. The other settings are ok, timed charge is still working. I like to be able to set the battery to discharge from 1600 onwards if there isn't much charge. I've tried resetting battery to default values, is there anything else I could try please?
Tony_W did anything change recently, or did it break spontaneously?
What inverter/firmware do you have. One behaviour I discovered recently on my system (gen-3 hybrid - might be a bug) is that if you configure a discharge window with a discharge limit, that limit is honoured even if timed discharge is not enabled. So rather than using the official timed-discharge behaviour (fully disabled discharge until given time) I can use multiple discharge slots to stage a descent - until 1pm, only discharge if above 60%; until 4pm, only discharge if above 40%, etc.
It seems to have broken spontaneously, Inverter Model is GIV-HY3.6, Firmware Version D0.909-A0.909. I don't see that I have the option to set a discharge limit at all, and although the discharge time is called "Slot 1", I haven't located where to set a second slot either.
