Test Island Mode

To test Island Mode, AC power to the inverter must be
disconnected. If configured to provide backup power to a
protected loads subpanel, this may be accomplished by
turning OFF the solar backfeed breaker or solar AC dis-
connect. If configured to operate with a PWRcell ATS, AC
power must be disconnected to the inverter and the ATS
to testing islanding.
– Ensure inverter setting "EnaIslanding" is set to
'on.'
– Ensure Protected Loads breaker at the inverter
Power Core is in the ON position.
– Ensure system is set to an appropriate system
mode (e.g., Clean Backup, Priority Backup, Self
Supply).
NOTE: Exact electrical system configurations will vary. It
is up to the operator to perform this test accurately for the
configuration onsite.
NOTE: Per UL 1741, the PWRcell Inverter may require
five minutes upon recovery from a grid outage or island-
ing event before exporting power.

Configure Time of Use (optional)

REbus Beacon allows the PWRcell system to manage
energy production and storage over the course of the
day. This is called Time of Use (TOU) energy manage-
ment. To take advantage of this functionality, the PWRcell
system must include a PWRcell Battery and a reliable
connection to the Internet via an Ethernet connection to a
router.
NOTE: Enable and setup the REbus Beacon for TOU
scheduling only. Otherwise, do not enable the REbus
Beacon.
