Ensemble Commissioning: Installer Toolkit Communications

___________Installer Initials: All steps complete on this page

Manually scan the serial numbers of Ensemble components into Installer Toolkit.

C.1.1. Enpower and Encharge serial numbers must be manually scanned, while

PV microinverters can use power line scan.

C.1.2. It is strongly recommended to manually scan the PV microinverters as a

power line scan can “poach” an incorrect serial number from a nearby site.

C.1.3. Note: The “LED status” indicator, and state of charge in Installer Toolkit will

be inaccurate until Envoy software is updated at the end of step F.

D. Energize Ensemble equipment in the following order:

D.1. Ensure Envoy and PV branch circuit breakers are turned ON in the IQ Combiner.

D.2. Ensure that the AC combiner, auto transformer and Encharge breakers are turned ON

in Enpower.

D.2.1. First, turn ON the AC combiner, then the auto transformer, then the

Encharge breaker.

D.3. For all Encharge units, ensure that the DC disconnect switch is turned OFF, then

power ON the Enpower by turning ON the utility breaker and/or any breakers on the

line side of Enpower.

D.3.1. Wait 60-330 seconds for the microgrid interconnect device relay to close.

DANGER! Ensure Encharge ground connection does not have a L1 or L2 connection, as this

introduces a safety hazard. To check correct wiring, follow these steps:

D.3.2. Ensure AC power is supplied to Encharge. The breaker inside of Enpower

must be closed, as well as any AC breakers between Enpower and

Encharge (if there is a battery combiner panel).

D.3.3. Using a voltmeter, measure the Encharge chassis metal to ground, (e.g.,

grounded conduit) and ensure there is no AC voltage source present. If

there is incorrect wiring, a ground fault may exist, and the AC voltage may

read ~120Vac. If voltage is present, DO NOT touch the chassis, immediately
