It tries to simulate the PVIP best questions for our customers to learn and test at the same time and it has been proved to be good environment for IT workers to find deficiencies of their knowledge in the course of stimulation.

After purchase, Instant Download: Upon successful payment, Our systems will automatically send the product you have purchased to your mailbox by email. (If not received within 12 hours, please contact us. Note: don't forget to check your spam.)

There is no doubt that the IT examination plays an essential role in the IT field. On the one hand, there is no denying that the PVIP practice exam materials provides us with a convenient and efficient way to measure IT workers' knowledge and ability(PVIP best questions). On the other hand, up to now, no other methods have been discovered to replace the examination. That is to say, the IT examination is still regarded as the only reliable and feasible method which we can take (PVIP certification training), and other methods are too time- consuming and therefore they are infeasible, thus it is inevitable for IT workers to take part in the IT exam. However, how to pass the NABCEP PVIP exam has become a big challenge for many people and if you are one of those who are worried, congratulations, you have clicked into the right place--PVIP practice exam materials. Our company is committed to help you pass exam and get the IT certification easily. Our company has carried out cooperation with a lot of top IT experts in many countries to compile the PVIP best questions for IT workers and our exam preparation are famous for their high quality and favorable prices. The shining points of our PVIP certification training files are as follows.

NABCEP PV Installation Professional (PVIP) Board Certification Sample Questions:

1. When installing an ungrounded PV system with an open-circuit voltage of 450Vdc and a maximum voltage of
3000Vdc which procedures should be followed to establish an electrically safe condition?

A) Determine possible sources electrical supply an avoid exposure to energized conductors or parts.
B) Verify that disconnecting device blades are closed and test conductors using an adequately rated detector.
C) Mount inverters on nonconductive supports and temporarily ground one dc circuit conductor.
D) Apply lockout/tagout devices and install a listed isolation transformer.

2. What is an arc-flash boundary?

A) The approach limit distance from energized electrical equipment within which a person is considered to be exposed to full circuit voltage.
B) The distance within which qualified personnel can safely perform bare-handed work on exposed energized electrical equipment operating at 50 volts or more.
C) The approach limit distance within which inadvertent movement exposes personnel to increase ris due to electrical arc-over potential.
D) The approach limit distance within which a person could receive a second-degree burn in the event that an electrical arc flash were to occur

3. A PV connection is being made at the center of a 300 ft. long 200 feeder. See the attack diagram. The feeder originates in the upper third of the 800A main service panel (800A main breaker) with a 200A breaker and terminates in a 200A main-lug-only subpanel. The rated output of the PV system inverter is 100A.

Which are the NIMUMUM actions required to achieve an NEC-compliant installation?

A) Install a 200A breaker at the PV source connection point on the portion of the feeder toward the subpanel, maintain the capacity of the entire feeder, and move the 200A breaker to the bottom of the main service panel, away from the 800A main breaker.
B) Install a 325A breaker at the PV source connection point on the portion of the feeder toward the subpanel. Increase the capacity of the feeder from the main panel board to 325A breaker to the bottom of the main service panel, away from the 800 main breaker.
C) Install a 325A at the PV source connection point on the portion of the feeder toward the subpanel, increase the capacity of this portion of the feeder to 325A, add a 200A main breaker to the subpanel, and move the 200A breaker to bottom of the main service panel, away from the 800A main breaker.
D) Install a 200A breaker at the PV source connection point on the portion on the portion of the feeder toward the subpanel and move the 200A breaker to the top of the main service panel, adjust to the 800A main breaker.

4. What is the maximum allowable voltage drop for a PV source circuit conductor run of 100 feet, using 10 AWG copper wire, if the system operates at 48V DC and the design specifies a 2% voltage drop?

A) 0.96V
B) 1.92V
C) 1.44V
D) 0.48V

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 an cable and connector rated for
30A. What is the MAXIMUM number of inverters that may be wired together on a single 30A feeder circuit?

A) 28
B) 17
C) 15
D) 23
