Battery wasn't charging or discharging
Same as some of the others on here, my installer has stopped trading. I was on a few fb groups for solar so sent out a message requesting any growatt details ad I couldn't find any specific uk phone numbers. I managed to get an email address and they replied within a day. Sent Me a whasapp message and sorted it all out over wifi. The first software update they did worked for a couple of days. So I messaged on WhatsApp, again they replied the same day and organised an engineer who came out just 2 days later. He couldnt have been mor helpful. Explained what he was doing and made sure it all worked before he left. Couldn't fault them at all
