ENPHASE STORAGE CERTIFICATION EXAM SCRIPT 2025/2026
QUESTIONS WITH ANSWERS GRADED A+
✔✔In this single line diagram, the PV rapid shutdown initiation device is shown as a
separate AC disconnect. The AHJ notified the installation company to move the
functionality of PV rapid shutdown initiation device to the breakers labeled as note 6
because there is not a location for the a separate AC disconnect with good visibility for
the fire fighters. What is the correct action on the single line diagram?
A. Add a label of PV shutdown initiation device to the breakers labeled as 6 showing
that there will be two PV shutdown initiation devices
B. Delete the AC disconnect and move the label of PV rapid shutdown to the breakers
labeled as 6
C. Leave the AC disconnect the way it is and move the label of PV rapid shutdown to
the breakers labeled as 6
D. Do not make any change to the single line diagram - ✔✔B. Delete the AC disconnect
and move the label of PV rapid shutdown to the breakers labeled as 6
✔✔True or false: Note 1 indicates that this is a single production CT for two branch
circuits and includes L1 conductors only but if we had four branch circuits instead of just
two, we would need to add one more CT for the L2 conductors of the two additional
branch circuits. - ✔✔False
✔✔Encharge 10 has three DC switches, one on each Encharge 3 base unit and they
are accessible without having to use tools. Why does the jurisdiction require a separate
DC Switches between Encharge and Enpower?
A. The distance between Encharge and Enpower on straight line is 10 feet and there is
a solid obstruction between them
B. There is no Encharge breaker on Enpower
C. Encharge breaker in Enpower is undersized
D. Encharge 10 does not have a single disconnect to shut down all three Encharge 3
base units at the same time - ✔✔A. The distance between Encharge and Enpower on
straight line is 10 feet and there is a solid obstruction between them
✔✔ Which component of the Ensemble system detects a grid failure?
A. Envoy
B. Enpower
, C. Encharge - ✔✔B. Enpower
✔✔True or false: PV systems with Energy storage but without backup power do not
require Enpower. - ✔✔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 - ✔✔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 - ✔✔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 - ✔✔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
