Very early usage. Only 9hrs since install. so far so good. I think it's great. current niggles are it takes around 5 minutes to refresh data. it'll tell you it's just done it and it has a pull down to refresh function but no matter what it's around 5 minutes. It needs a dark mode and needs to change SOC "Health" to "Healthy" for proper English. otherwise so far I'm happy! will report here any issues.

Thanks for your feedback! Dark mode is coming soon, and "Health" will be updated to "Healthy" in the next version. For the 5‑minute data refresh delay: real-time updates are only available on certain models. Please check the "..." menu​ on plant page—if you see "Real-time data", enable it. If not, your device does not currently support live data.

Update: The previous bug has been resolved. Overall it is a feature rich stable app with resonable transparency as to the key AI function. Some quirks still persist. During peak shaving I see frequent small negative price exports despite low SOC and backstop enabled. I don't know if it is a measurement error or real export issue. I will have to verify with my energy supllier.

Sorry for the trouble. If the app shows "offline" but the system is still working, it's usually a connectivity issue. Please try restarting your router and the inverter's device. If the problem continues, contact us with your inverter's serial number (SN) at service@saj-electric.com​ for assistance.
