Introduction:
This document contains the complete set of Enphase Solar PV
Installation Certification Training exam questions along with 100%
correct answers. It comprehensively covers all modules of the
Enphase certification program, including microinverter operation,
system design, installation best practices, wiring and grounding,
monitoring with Enlighten, use of the Envoy gateway, safety
standards (OSHA and fall protection), and troubleshooting
procedures. Ideal for installers and technicians preparing for
Enphase certification or seeking a detailed study reference.
Exam Questions and Answers
Where do you go to find data on a system you have built?
A. personal email
B. Enlighten
C. Enphase.com
,D. You have to go back to the site --- correct precise answer ---B.
Enlighten
True or false: Enphase Q Cable works with other manufacturers'
equipment. --- correct precise answer ---False
What impact does temperature have on solar panels?
A. Direct relationship, hotter panels convert more light energy into
electricity
B. Inverse relationship, hotter solar panels have lower voltage,
cooler panels yields higher voltage and more power
C. Temperature has little impact on solar panels, AC voltage is more
crucial, next is light intensity
D. They increase power output when warmer due to less resistance
--- correct precise answer ---
Do solar panels deliver a constant STC rated output when installed
at most homes or businesses?
,A. No, but it is required that solar panels never exceed the inverter
rating
B. No, solar panels have a maximum output rating and do not
exceed that
C. No, solar panels typically are warmer and have less light
reaching them than in the STC factory test conditions
D. Yes, if they didn't the customers would return them or get
payment as part of their 20 year warranties --- correct precise
answer ---C. No, solar panels typically are warmer and have less
light reaching them than in the STC factory test conditions
When designing solar systems, selecting the right microinverter
and solar panel pairing based on power output requires analysis.
Which of the following statements is the most accurate?
A. Because microinverters are a series DC string circuit, the correct
minimum and maximum number must be carefully observed
B. To claim STCs the output of each microinverter can be no less
than 75% of the output of the solar panel that it is connected to
, C. Selecting solar modules with power output lower than the
inverter output is a good idea because all solar panel output will
always get captured
D. You cannot have the solar panel DC wattage exceed the
microinverter output wattage as the microinverter could get
damaged --- correct precise answer ---UNSURE, but it's either
B. To claim STCs the output of each microinverter can be no less
than 75% of the output of the solar panel that it is connected to
OR
C. Selecting solar modules with power output lower than the
inverter output is a good idea because all solar panel output will
always get captured
(I tried A and D and both were wrong, but I have no more attempts
- so let me know which one it is so I can update this)
What factor(s) primarily impact the maximum quantity of
microinverters per AC branch circuit?
A. Light intensity and temperature averages at the installation site
