erac  PWRcell  Inverter  Owner’s  Manual  for

more information.

See 

Figure 6-1

To access the device page for

each  PV Link,  use  left or  right  arrow  buttons

(A)  on  the  inverter  control  panel  to  scroll

NOTE: 

The PV Link only produces power after

the REbus DC nanogrid has been established

and the device has been enabled.

Commissioning the Rebus 

System

The  PV  Link  ships  from  the  factory  in  a  dis

-

abled  state. Each unit  must be enabled  from

the  PWRcell  inverter  control  panel.  Once

enabled, the PV Link automatically detects the

REbus  nanogrid  and  begins  to  export  power

when the bus is within normal operating speci

-

fications.

See the Generac PWRcell Inverter Installation

Manual for instructions on commissioning the

REbus system.
