I have a Multiplus II GX 5kVA with 3 x US3000C Pylontech batteries and some solar panels, running in ESS mode with grid feed in. I have setup Node-RED to send me an email whenever the "AC Input" changes (see screenshot).
I'm seeing that the inverter is going into "Inverting" mode when there is mains present. This is when there is no solar, so I can't see why this should happen. I have also setup a "grid lost" alarm, but this isn't triggered.
It's not causing me any problems, but I'm trying to understand why it's happening as part of bigger plans to use the change in "AC input" to trigger various actions via Node-RED. (I'm a noob to Node-RED, so maybe I'm doing something stoopid...)
