Question 1

Which of the following is an NEC requirement regarding access for large-scale PV electric power production facilities?

A : Field-applied hazard markings must be installed, and access to the supply station is to be restricted by fencing or other adequate means.

B : All fencing and associated gates must have ac and dc current and voltage exposure labvels and must be electrically isolated from the solar facility.

C : Arc flash warning labels must be field-applied by the installer at all access points for qualified persons and at the point of the utility interconnection directory.

D : Access to remote isolating equipment for servicing is allowed for individual other than qualified persons when the equipment is enclosed within a secure structure.

Answer: A

Question 2

A homeowner is weighing the PV module options for a roof-mounted solar array. Which is a correct option to present to the homeowner?

A : Building-integrated PV shingles will be flush or nearly flush with other shingles, but the electrical energy produced will be less than polycrystalline or monocrystalline modules.

B : Rapid shutdown requirements within 1 ft of the array boundary.

C : Polycrystalline modulesare more shade-tolerance than eitheramorphous or monocrystalline modules and allow a larger array to be installed, including in area where shading could be seasonally problematic.

D : Microinverters can be installed with either polycrystalline or monocrystalline modules, negating the need for rapid shutdown compliance.

Answer: D

Question 3

A customer has a 200A service with a 200A rated panel and 200A main breaker located on the street side of the house. There is a 100A breaker located at the opposite end of busbar feeding a 125A subpanel in the backyard. The customer would like to place the inverter the backyard and use the 125 subpanel. Which MAXIMUM inverter(s) output circuit current could be installed?

A : 30A

B : 32A

C : 40A

D : 42A

Answer: C

Question 4

A residential PV system uses two 120.240Vac utility-interactive inverters with a sealed lead-acid battery energy backup for protected loads. The MOST important protected load consideration when operating in the backup mode is that:

A : The protected loads must have automatic restart function.

B : All protected loads are connected in multiwire branch circuits.

C : The peak current from the sealed lead- acid batteries must not exceed peak demand currents.

D : The stand-alone system configuration can adequately supply current to all protected load branch circuit.

Answer: B

Question 5

A PV system installation utilizes micro inverters connected to each module of the array. Each micro inverter has a nominal rated output of 250WV. Single phase. The microinverters are listed so that multiple inverters may be connected in parallel to a single feeder circuit, and each inverter has ancable and connector rated for 30A. What is the MAXIMUM number of inverters that may be wired together on a single 30A feeder circuit?

A : 15

B : 17

C : 23

D : 28

Answer: C
