Hi
I had installed a Multiplus II 48/5000/70 with 3 x 5kWh batteries installed but it's not working. I can charge the batteries ok but when I switch the unit over to Inverter mode nothing happens. I've attached a diagram of the installation below - is the issue that the ET112 is in the wrong place?
(Just realised there should also be a line from the batteries to the GX for the BMS)
Thanks
Mike
