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 - CORRECT
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 - CORRECT
ANSWER B. Because Encharge batteries operate 240 VAC line to line and split phase
power systems require a neutral
