There’s a few things you can do.
1. Make sure the Solar breaker(s) in your electrical panel is/are ON
2. Check your SolarEdge inverter and ensure the LIGHTS are the proper color. For APS, check your ECU to ensure you have two steady green lights.
3. Check your app to see if there is Solar production (note if there is snow covering the panels)
Note that your system may be working and only just disconnected from the internet.
