App time is +1 hour ahead of BST

At 7:15 this morning I turned the oven and kettle on, so as to load the system. I then opened the GE app to look at the battery graph. This graph appeared to show a spike in energy at 8:15? I have my battery programmed, via the app, to draw power between 2 and 5am (Octopus flux) but I am now thinking that it will actually be drawing power between 1 and 4 am? Has anyone else having the same issue?

Make sure your inverter is set to GMT time in the web portal. It's on the account settings page.

The system will take care of GMT to BST.

You can also sync the time after doing that, if need be, via the MyInverter page and then the remote control cog icon. Then scroll down to inverter, time and date and press send I think.

Thanks. Don’t know how long that has been like that.
