I have a schedule to top the battery up to 30% between 02:00 and 02:29. Looking at the graphs on the Android and Cloud apps, it looks like it kicked in last night at 03:00 to 03:29, so it didn't pick up the hour change (or both graphs are wrong?). When does the clock sync to BST? Does it have to be manually forced? If so, how?

It's not a perfect switch, in that they have to write to every inverter that needs to be changed and from past experience this seems to take time and can occur between 2am and approx mid day - You can set the clock yourself via the inverter panel settings if you want to speed it up.

Hmm. The inverter front panel shows it has switched. Does this mean that the schedule will follow automatically or do I need to reload it?

Why doesn't it run an NTP client? Microsoft does not have to write to every PC, Google to every Android device Apple to iOS etc They just automatically change at the right time.

The schedule runs in local time, if the local time has switched the schedule will follow that and shouldn’t need refreshing.
