Thanks, I'll give that a shot. When playing with settings I was able to get it to charge from AC1, just not the solar which is on the load side. I tried zero export settings but that seems to curtail rather than charge ...
I'm setting up homeassistant to read the Modbus registers, I'll try...
It won't charge the batteries from solar, (which is on the ac output) only from the ac1 grid. I'm using eg4-LL v2 in closed loop mode with a wattnode current meter for the loads on the grid side panel.
