Connecting The Storedge Interface To The Inverter - SolarEdge StorEdge Installation Manual

Connecting the StorEdge Interface to the Inverter

To connect to the inverter DC:
1. Prepare one pair of DC cables with MC4 connectors at both ends - male at one end and female at the
other end.
2. Connect one end of the cables to the inverter, and connect the other end t o the DC+ and DC- input
connectors marked INV OUT.
NOTE
If all the inverter DC inputs are connected to PV strings, use a branch cable (available from
SolarEdge) to connect the StorEdge Interface to the inverter DC input.
To connect RS485 communication to the inverter:
RS485 wiring specifications:
Cable type: Min. 3-wire shielded twisted pair (a 4-wire cable may be used)
l
Wire cross-section area: 0.2- 1 mm²/ 24-18 AWG (a CAT5 cable may be used)
l
1. Connect one end to the RS485 terminal block marked "RS485 to Inv." in the StorEdge Interface:
a. Open gland #2.
b. Remove the seal from one of the openings and insert the wire through the opening.
c. Connect the wire ends in the A, B and G pins (use a twisted pair for A and B): Use a flat blade
screwdriver to press the protrusion at the top of the terminal block a nd open the connection
hole; insert the wire and release t o spring back and clamp the wire.
You can use any color wire for each of the A, B and G connections, as long as the same color wire
is used for both A pins (inverter and StorEdge Interface, the same color for both B pins and the
same color for both G pins.
2. Connect the other end of the communication cable to the inverter communication board:
NOTE
The wires from the meter and from the StorEdge Interface are inserted into the same pins in the
inverter RS485 terminal block. Make sure that the meter wires are not disconnected when
inserting the Interface wires.
a. Open the inverter cover as described in its manual.
