For anyone who is thinking about adding an ig plus , not all have the mg 50/60 settings on the brain, apparently if not they have to be sent to Austria to be programmed, updating firmware will not add this feature as I have found out! On a separate note, should the multi bus state not show up on VRM when being charged from pv inverter on ac out? Mine is just showing that it is inverting , but led s show up on front panel
