Do not touch Growatt
I had the inverter installed in September. Numerous problems - the load isn’t showing anything unless the PV is on and always under what the PV is generating. UK support have washed their hands as the inverter is not a ‘UK’ model. Growatt China won’t respond and I have been trying to raise a warranty claim to no avail because they won’t respond to the issues. 8 months on and it still isn’t fit for purpose.
