I have a Growatt SPF3000 and that runs my off-grid chalet and have issues getting it to update the servers to het updated data... It used to run well at the beginning a few weeks ago and then it stopped updating the server. I may have found the problem today. Since I installed an Honda EU7000is generator, I changed the setting from SBU to UTL so that when I start the generator, it will use it to charge the batteries and the load. When I turn off the generator it goes back to solar and battery so that seems ok. Well I also lost update of my data from the Wifi datareader... After a a few reset I think I realized that maybe if UTL is set and it goes to battery most of the time it may not update the data to save energy as this would be a "backup more". So I got back to SBU which was my first mode when date was updated and it seems to be working again. Just wanted to share this and maybe others have issues like I had.
