Connecting The Strings To The Inverter; Connecting The Energy Meter - SolarEdge StorEdge Installation Manual

11. Verify that there are no unconnected wires to the inverter and that the unused
terminal screws are tightened.

Connecting the Strings to the Inverter

Connect the string to the DC input pairs. If required, connect additional strings in
parallel using an external combiner box/branch cables before connecting to the
inverter.
NOTE
Functional electrical earthing of DC-side negative or positive poles is prohibited
because the inverter has no transformer. Grounding (earth ground) of module
frames and mounting equipment of the PV array modules is acceptable.
NOTE
SolarEdge's fixed input voltage architecture enables the parallel strings to be of
different lengths. Therefore, they do not need to have the same number of
power optimizers, as long as the length of each string is within the permitted
range.
Connect the DC connectors of each string to the DC+ and DC- connectors. See Figure 5 .

Connecting the Energy Meter

For Smart Energy Management applications, such as maximizing self-consumption, the
StorEdge solution requires an Energy Meter.
To install the Energy Meter, refer to the installation guide supplied with it:
http://www.solaredge.com/files/pdfs/solaredge-meter-installation-
guide.pdf.
For communication, the Energy Meter and battery use the same port - RS485-2.
Use a 3-wire shielded twisted pair cable, 0.2 (0.2-1) mm² 600V or CAT5.
