In this case the DC run will go under the house in the crawl space before exiting the foundation and up to the DC disco on the inverter. With inverters that incorporate AFCI on the PV side, I couldn't come up with a good answer. Bill Battagin Feather River Solar Electric 4291 Nelson St. Taylorsville, CA 95983 530.284.7849 / 6544 fax
