Hi Jay, This is a new issue, but I don’t believe it’s generator related. Without CC comms plugged in, generator is steadily charging. It was serviced recently and has solid voltage and frequency under load.
I am all for leaving the comms disconnected, but unfortunately there is no screen on the FM 100, so PV output wouldn’t be visible.
