Can,t program inverter numbers into my inverters.
Have been using 2 fronius inverters for gt inverters and have a personal display in house. I got a deal on another display and when I checked it out neither display will work now. Now I found you can,t use 2 separate displays with the same inverters as the cards in the inverter need programed to the display. You can use up to 15 separate inverters with a display. Each inverter needs the IG number set different for each inverter from 00 thru 15. The inverters wont except any inverter number when I try to program the IG number. What can I do? I am thinking of cutting off the ac and dc power to inverter to see if anything will reset in the inverters. The inverters are working perfectly otherwise but I do like the personal display in the house and would like to get that working again.
