Battery timed charge

I have always charged the battery at night so as to run the house during the day. Since the new App whilst the timing for so doing is still set it is not charging. The app/software is up to date. How do I make this work?

Alp1963 does the battery schedule bar at the bottom of the app screen confirm that it plans to "buy" overnight?

I cannot see a battery schedule bar - the screen I am looking at appears as below

You need to click the back arrow and go to home dashboard

Sorry I have now seen the bar and it shows “buy” for the period I have set.

Alp1963 Okay, that seems to confirm that the configuration is correct. At night, does your home run from grid, or does it continue to run from battery (until it runs out).

One (unlikely) option is that the grid power percent has been set to 0. That configures the max power when charging from grid, but doesn't affect charging from solar.

What sort of system do you have? IIRC there are multiple registers configuring the max charge. It's possible that the app is showing the wrong one. Unfortunately I forget the details... Not sure if the app shows them all.

I tend to trust the Direct Control view, rather than the settings page. My gen-3 hybrid has relevant registers such as
enable AC charge upper % limit
AC charge enable
Battery Charge Rate
Battery Charge Power Percentage
AC Charge 1 Start Time
AC Charge 1 End Time
AC Charge 1 Upper SOC % Limit.

If necessary, you can press the button to force a read, in case the app has cached an incorrect value.

If you're on premium support (eg through Axle), there's also the remote control page on the portal, which should show much the same. Though that does show both "AC Charge Upper % Limit" and "AC Charge 1 Upper % Limit".

Thank you for your time on this but I am afraid this way over my head and I really do not understand. I just want to charge the battery at night on the cheap electricity - is there a way to contact Giv directly about this as I cannot find anyway to so do?

Alp1963 Is your installer still in business? If so perhaps you could ask them about your issue.

You could also get help from https://www.predsupport.com/ . This is a paid for service being run by ex GivEnergy employees.

Alp1963 It's very unlikely to be this, but have you tried setting a charging period that doesn't span midnight? Eg 00:05 to 05:01 ? It's a very easy way for developers to make mistakes.

(I have a feeling the pause timer misbehaved in this area on at least one firmware release.)

DD No, it was the 10-step charge current reduction (when battery hits 90%) which didn't work over midnight.
