Q45. In the middle of a winter day, the data acquisition system for a ground-mounted PV system with large central inverters sends an email alert that system performance is at 50% based on irradiance and temperature performance calculations. No inverters are completely offline. The closed technician is a 4-hour drive from the site, and there are no cameras on site. Which is the BEST response to this situation?

Q46. An installer was asked to provide a means to measure the voltage of each battery in a system. The bank is located 50 ft.
From the data logger. The installer will be using shielded. Twisted pairs of instrumentation wiring, all run in the bundle a conduct.
The signals are connected to isolated and ungrounded inputs at a data logger. Which safely precaution is MOST needed to protect the instrumentation wiring?

Q47. Which load path connections need to be analyzed when determining live and dead loads on a PV array system installed directly to a metal seam roof?

Q48. Inspection of a new PV installation shows that the dwelling uses a galvanized water pipe for its grounding electrode and that the PV system now shares the connection. Which of the following is an acceptable supplemental electrode method to ensure the integrity of having a grounding electrode?

Q49. 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?
