EG4 18k PV inverter output goes to zero

Lots of pictures.

EG4 18Kpv operating good  all summer.

Yesterday (October 9)  inverter stopped outputting power to loads (seen on the solar-assistant screen shot image)

The EG4 monitor screen screen shot shows current operation, loads supplied from grid, battery is full.

Finally, the .pdf of the setting from the eg4 web app. 

Disconnected solar-assistant  so I could use  the EG4 WiFi/web app. (using MODbus connection from 18kPV to an orangePI , which will not operate with the EG4 WiFi dongle plugged in)

I don't see a setting problem, (in Remote_Set_3464660401.pdf) 

All the attachments should provide total information on firmware versions and settings.

So far, a mystery.
