Currently I am using 71 inverters with a capacity of 132kw ALTIVAR. In the process of using it broken controller card, I've replaced them with controller card with a capacity of 55 kW, when I replaced them on the power play finished, they report them. I checked and found card software 55kW power control software is 1.5, while the blister card 132kw power control is 2.1. You just help me how to upgrade the software controller card with a capacity of 55kW to 132kw.
Thank you very much !
