Connecting the Backup Interface (Optional)

The Backup Interface must be installed to allow the operation of batteries.
When connecting the Backup Interface to the inverter, use the following cable types:
Communication - 0.25 mm
12V power -
If the distance between the inverter and the Backup Interface is smaller than 15
m, use the CAT6 communication cable (see above).
If the distance is greater than 15 m, use a dedicated cable with a cross section of
2
1.5 mm or greater.
To connect the Backup Interface:
1. Connect the communication and 12V power cables to the Backup Interface, as
explained in the installation manual that comes with the Backup interface.
2. Open Communication Gland 1 at the bottom of the Connection Unit.
3. Feed the other end of the communication cable through one of the gland openings.
4. Remove the 7-pin connector from the port labeled Backup Interface on the
communication board.
5. Connect the communication cable wires to the 7-pin connector, as shown below.
6. Close Communication Gland 1 to a torque of 5.5 N*m.
Connecting an External CT to the Energy Meter
(Optional)
To enable import/export or consumption metering, connect an external current
transformer (purchased separately from SolarEdge) to the Energy Meter.
