SEMS+

I have given this app only a 2 star review because I have it set up to alert me to Inverter failures so that I can contact GoodWe when it happens to get diagnostic information for my Solar providers and it NEVER gives me real time notification of the inverter failures. So, 2 things need to happen. Fix your inverter from failing so often and fix the app to provide real time notification.

My GoodWe inverter was working normally until 4 October 2026. Since 5 October, SEMS has been offline. The inverter displays Normal, but the Wi-Fi module's yellow LED flashes twice, indicating it is not connected to the router. I have restarted the inverter and router and reconfigured the Wi-Fi module through its web interface, but the problem persists. Two different phones show the same issue.

Unable to view total units generated for previous months. In the App, when viewing the Monthly Generation report, only a daily bar chart is displayed for the entire month. There is no clearly visible total monthly generation (kWh) figure summarized below or above the chart. Please add a prominent Total Monthly Generation summary value on the monthly report view, so users do not have to manually calculate the sum of daily values. This would greatly improve the user experience.
