ENPHASE CERTIFICATION EXAM
PACKAGE 2026 FINAL PAPER EXAM
SCRIPT WITH SOLVED QUESTIONS GRADED
A+
⩥ True or false: PV systems with Energy storage but without backup
power do not require Enpower. Answer: True
⩥ Where do the hot conductors between Encharge and Enpower
terminate?
A. In the IQ Combiner box
B. At the DER (distributed energy resource) input terminals
C. On the Encharge circuit breaker terminals
D. On the PV circuit breaker terminals
Clear my choice. Answer: B. At the DER (distributed energy resource)
input terminals
,⩥ What is the maximum amount of PV and storage that can be
connected to the Enpower smart switch?
A. 80A of PV and 80A of storage for a total of 160A
B. 80A of PV or 80A of storage for a total of 80A
C. 40A of PV and 40A of storage for a total of 80A
D. 0A, PV and Storage is landed in a backup loads panel. Answer: A.
80A of PV and 80A of storage for a total of 160A
⩥ Do we need to install an additional service disconnect if the Enpower
main service breaker has been installed as the main service disconnect?
A. No, it is not necessary to install an additional disconnect
B. It depends on the use case
C. Yes, it has to be redundant and serve as a rapid shutdown initiation
device. Answer: A. No, it is not necessary to install an additional
disconnect
, ⩥ Why does Enpower need a Neutral Forming Transformer to operate
during the grid outage?
A. Because NEC 2017 requires a transformer to have reference to
Neutral
B. Because Encharge batteries operate 240 VAC line to line and split
phase power systems require a neutral
C. Because when the grid is down the micro inverters operate on 120
VA. Answer: B. Because Encharge batteries operate 240 VAC line to line
and split phase power systems require a neutral
⩥ The above system was initially estimated to require three Encharge 3
equivalent to one Encharge 10 and no soft starter. After the site survey,
they found that the largest single load in the backup load center, is going
to be a 3 kVA electric motor with a start current of 32 Amps at 240 VAC
for 3 seconds.
Is the estimated size of one Encharge 10 going to be enough to comply
with NEC 2017 710.15 (A) without using a soft starter?
A. Yes, one Encharge 10 will comply
