Customer Support?
There is no ability to change operating modes in the app and no way to contact customer support. I’m not sure why they have a customer support section. I’ve tried opening three customer support cases and they just get closed out after a few days without any communication or resolution.
Never works
App is offline more than on saying no data available from the battery then suddenly works for an hour or two before going offline again. Battery service is just as bad bought a system which was expandable and is still in warranty period but they no longer produce or support the model. I would not buy sonnen again

Worse than ever
App seems to get worse with each release. Annoying screen flashing on start up. Can no longer find record of grid outages.
Terrible Customer Supporting
Had battery for 4 years loads of battery and customer service issues, decided to rip out system and replace with Tesla Powerwall 3. Best decision. Time, money and energy really not worth the effort with sonnen.
No control
The app only allows you to change the backup buffer. No control for time if use charging, no ability to charge or discharge the battery. Now even appears to have lost its history “Achievements” where you could previously see when it provided power in a grid outage and energy self sufficiency. Battery seems to work well but app needs a lot of work.
