PWRcell ATS

Figure 5-18. PWRcell ATS
A Generac PWRcell ATS is integrated into the PWRcell
installation to facilitate
configurations. Refer to the PWRcell ATS Installation
for additional
Manual
configurations and installation instructions.
NOTE: Improper installation of a PWRcell ATS can result
in an objectionable current path through a paralleled
neutral connection. Reference NEC 250.6. The neutral
conductor for the inverter AC Grid Connection circuit is
not required to be installed to the point of common
coupling with the utility as permitted by the exception in
NEC 200.3. Follow the PWRcell ATS Installation
Manual for proper
responsible for compliance with applicable national,
state, and local codes.

Load Management Options

Load management systems are designed to prevent a
power source such as an inverter from being overloaded
by large appliance loads. Options include:
•
PWRmanager: Advanced Load Controller

NOTE: PWRcell systems with AC Generator Integration
is
should NOT use the PWRcell ATS Controller for load
management. PWRmanager or other appropriate load
management solutions may be used instead.
When utilizing these load management solutions be sure
to select the appropriate value for the "EnaLoadShed"
setpoint. This setpoint is accessible through the Mod.
Settings menu via the inverter device page as shown in
Figure 5-22.

•
Select a value of "1" if using PWRmanager and/or
SMMs only to manage loads.
•
Select a value of "2" if using the PWRcell ATS
Controller (with or without SMMs) to manage
loads.
NOTE: When installed with PWRmanager, SMMs should
be used with lockout switch set to "Lockout Load on
Generator" only. The 24 V HVAC relays on the PWRcell
ATS Controller are not compatible for use with
PWRmanager.
