I am installing a new rooftop 4.6KW solar array with the MNPV8HV-DISCO disconnect box and remote Birdhouse to comply with my fire-code. I understand the Disconnecting combiner must be within 10 ft. of the array. If the side of the house where I mount the disconnect is within the 10 ft. requirement is that OK or does the box have to be mounted on the rooftop? I would prefer to put it in a vertical configuration if possible but to reach the box would require a ladder to access it if it was installed on the outside house wall. Any information appreciated.
