PV Grid-tied Residential Inverter and Integrated AC/DC Disconnect
Installation and Operation Manual
27
Note:
An exception exists if a dedicated PV system AC sub-panel is
used to combine multiple inverters. The dedicated PV system
AC sub-panel requires a single breaker at the main utility
service panel for a multiple inverter installation.
Preparing for Wiring Multiple AC/DC Disconnects
The wiring raceway in the AC/DC disconnect allows a continuous run
of the AC, DC and system ground conductors between multiple inverter/
disconnect units.
1. Make sure each disconnect ON/OFF switch is in the OFF position.
2. Remove the screws from the lid of each disconnect.
3. Remove the side knockouts on each disconnect to access the wiring
raceway.
4. Insert a fitting in each knockout opening so a continuous, water-tight
connection is created between each disconnect.
5. Route the AC, DC and the system ground conductors through each
disconnect, terminating applicable connections.
For instructions on connecting the PV array and the AC conductors inside
the disconnect, refer to the section
Wiring a Single Inverter with an
Integrated AC/DC Disconnect on page 21.
Connecting the Ground Conductors of Multiple Units
System grounding requirements for a multiple unit system also uses a
single-point ground.
1. Connect the EGC coming from the first PV array to the grounding lug
inside the disconnect cabinet of the first unit.
2. Connect the remaining units with a continuous EGC, branching from
grounding lug to grounding lug.
3. On each unit, connect the EGC from the utility grid to the grounding
terminal of the AC connection.
