I have a Fox ESS HC1 Inverter and a master plus slave ECS battery.
Yesterday we had a fairly significant internet failure and after everything returned the WiFi communication unit was flashing rapidly. Nothing I could do resolved the WiFi issue until I followed the instructions to restart the Inverter. This reconnected everything and after a few minutes the WiFi connection worked and the app started reporting the SOC etc.
However, I noticed that at the end of the whole process the lapm on the Slave battery was flashing green as was the slave lamp on the master battery.
I havening been able to locate any useful guidance on the lamps on the batteries. I confess that I did not notice if the lamp was flashing before I started the restart process or if this is a new warning.
Does anyone have any insight please?
Much appreciated in advance.

Green flashing is perfectly normal - the master (BMS) polls all the batteries every few seconds and the green light flashes like a heart beat when it does. If it’s a red light flashing it’s a problem !
