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
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
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.
