Support

I have a system with batteries that seems to function quite well and has done for a couple of years. My problem is that for some months now the data reported either via the App or via the portal is rubbish. For example several Mw of power generated in a day - all power going to the grid and none to the house etc. etc. Given the apparent lack of support from Givenergy (yes ive sat on the Whatsapp for ages) is there some form of reset possible to get the system back reading data correctly or could my installer offer some remedy ?

Yes, the responsiveness of the WhatsApp Helpdesk is deteriorating rapidly.
I sat for three hours with some guy called Armaan Bukhari who bid me good afternoon at 10.00 am! Have they outsourced this service abroad?
I've tried two other times and always get through to Armaan. So, either they're all called Armaan or the service is hopelessly understaffed.
After 3 hours he became bored and cut me off without addressing the problem.

LMA the data reported either via the App or via the portal is rubbish

Other apps are available which may give you better results.
