Hi, I have a query regarding addding new inverter to the system. Whenever I have done this, my system production reduces than the other inverter I'm using. Take it as example. I am using 125kW Sungrow string inverter. One is already in PVSOL database and I tried to add a new updated version of it in PVSOL. The moment I selected it, my production got reduced as well???? I'm looking forward to hearing from you soon. Kind Regards, Sharjeel
