Hi,
I am designing a job with traditional string inverters and was asked about the fused input rule. It has been a long time since I have been asked or have needed to be concerned with that code rule, which I think has since been taken out of the code? There is an inverter we are working with that is a 50kw and allows for 12 string inputs, 2 strings per MPPT circuit input. It is the SMA Core1. I thought the old code was a maximum of 3 string inputs into the inverter. Can somebody help me out with this and reference a code section for me to give to the plan checker?
Thanks ahead of time for your help!
