A grid-interactive PV system with battery backup is being installed with a ground-mounted PV array located
200 ft, from the inverter and batteries. The dc PV output circuit has overcuit has overcurrent protection rated from 30A. To reduce voltage drop between the array and batteries, the output circuit wire size was determined to be 6 AWG. The fused dc disconnect between the inverted and batteries is rated for 300A. What is the required size of the equipment grounding conductor between the metal battery case and the inverter?

A rooftop PV system is being installed on a residential building with a 30-degree tilt angle. The modules are oriented directly south in a location where the solar noon altitude on December 21st is 30 degrees. What is the minimum distance required between two rows of modules to avoid shading between 9 AM and 3 PM solar time, assuming the module height is 3 feet?

According to the NEC, if the PV system disconnect and the building service disconnect are at different locations, there MUST be a/an:
