We are installing a ~100kW PV system on the roof of a building. For interconnection we had planned to tie the inverter outputs to a new panel on the roof and bring the feeders down into the building at the 800A service panel. The only available breaker space will not accommodate the 110A breaker that we would need, so our backup plan is to mount a fused disconnect next to the service panel and feed it off the panel's load-side lugs. Is there something in the code that would restrict this plan? It seems to me that if we were to connect to the supply side, there would be no issue, but I can't seem to find anything for or against connecting to the load side lugs of the service panel.
Thanks in advance.
