Useless
So, so unhappy with my Growatt inverter and battery. The app is shocking and never connects. I can't trust the data as it updates so slowly. Buy cheap buy twice. Wish I had listened to the company telling me I would regret it. **Update** I have now received a different inverter and battery from a far more reputable company. I am so pleased we had an install from company with a conscious. They changed it all out for us F.O.C. Growatt support was virtually useless.
