Devices
DANGER
Electrocution. Never enable any device during an
installation or while wires are exposed. Doing so
will result in death, serious injury, or equipment or
property damage.
NOTE: All PWRcell devices are enabled and configured
individually through the PWRcell Inverter control panel.
The inverter must be enabled and in state, "grid con-
nected," before REbus devices can be configured and
enabled. If not already enabled, see
Inverter.
Configure REbus Devices
Configure REbus devices settings connected to the sys-
tem using the instructions provided in the Commissioning
section of their respective installation manuals.
Enable REbus Devices
Enabling REbus devices is the same procedure as
enabling an inverter but on the individual REbus devices
pages. See

Test Island Mode

To test Island Mode, AC power to the inverter must be
disconnected. When configured to operate with a PWR-
cell ATS, AC power must be disconnected to the inverter
and the ATS to test Island Mode.
For Service Entrance rated PWRcell ATS, this can be
achieved by turning OFF the main breaker integrated into
the enclosure.
For non-Service Entrance rated PWRcell ATS, this can
be achieved by turning OFF the circuit breaker for con-

ductors feeding the "N" terminals of the PWRcell ATS.
Verify the following prior to an Island Mode test:
– Inverter setting 'EnaIslanding' is set to 'on.'
– Ensure 'NumTranSwtchs' reflects the number of
ATS installed.
– 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
013444
configuration onsite.
NOTE: Per UL 1741, the PWRcell Inverter may require
five minutes upon recovery from a grid outage or Island
Mode test before reconnecting to the grid.
NOTE: For anti-islanding tests, turn OFF the solar back-
feed breaker or solar AC disconnect connected to the
inverter's AC Grid Connection terminals to properly mea-
sure absence of voltage.

Configure Time of Use

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
