The inverter screen should illuminate. At this time, it will
be necessary to enable the inverter and other connected
REbus devices.
NOTE: When a Shutdown is initiated on a PWRcell
system in Island mode, all communicating REbus
devices will disable and power off. The Shutdown is not
considered to be actively maintained in this case, and a
manual enable can be used to Blackstart the PWRcell
system and clear the Shutdown state.
NOTE: Local code adoption may require the installation
of additional DC disconnection means between battery
and inverter which can impact the ability to Blackstart a
system if disconnect means is in OPEN or OFF position.
NOTE: Generac does not currently support autonomous,
off grid installations with PWRcell equipment.
