Have you tried my reboot sequence posted earlier?

Did a cold reset, Goodwe could access the inverter (before it went offline again) and they updated the firmware remotely. Not a single drop since then (2 months plus).

One thing I have not tried, and it makes sense. But don't want to put fingers in 'somewhere' until I am comfortable 🙃 A cold reset did it again (Goodwe response - AC off, rotatary switch, batteries, then reverse - posting it here just in case someone is unsure). That said, I want it to work ALL the time without requiring the use of a screwdriver, and a LAN module seems to be the way forward. Except I can't trace one online to buy. Have asked Goodwe for a local supplier.

Tried all the stuff and a cold reboot by installer fixed it. I did not pay attention 😐 Was changing parameters in PV today, but somewhere something went wrong (parameters were not saved, and the setting for DOD off-grid now also gone, probably because it is not connected). Anyway, want to do a cold boot, but want to make sure. Switch off 2 switches on DB next to inverter (main switch last, no need to switch leakage one off), then rotary switch under inverter to off, then wait a while, then reverse ie rotary switch to on, and then the DB switches. Is that correct? Thanks!
