My GivEnergy time was an hour difference to real time before the clocks went back it is now 2 hours difference. For example if I want to charge the battery from 1 am to 5 am I have to set it to charge from 3 am to 7 am. Is there any way to correct this.
Sounds like it was commissioned with the incorrect time zone.
L159152 Have you tried using the givenergy cloud portal? If you expand your inverter from the dashboard then click the cog wheel (remote control). The second heading down should be ‘Inverter’, the first option is ‘Set time and Date’. You could click the send button to see if that changes it for you. There doesn’t seem to be a way to set the time and date manually, so I would presume that this will send the current time and date of the device you use to send the command.
L159152 Go to account settings on the portal and select the correct time zone
After looking this setting appears to be under "Account Settings" on the Portal.
