Connecting The Pv Strings To The Synergy Manager - SolarEdge Se K Series Installation Manual

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 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.
WARNING!
Turn OFF the AC before connecting the AC terminals. If connecting
equipment grounding wire, connect it before connecting the AC Line and
Neutral wires.

Connecting the PV Strings to the Synergy Manager

The inverter is designed with three DC input terminals. Nevertheless, each input may
connect to several parallel PV strings via an external combiner box. The combiner box
should be installed and connected before connecting to the Synergy Manager.
This simplifies the commissioning of the inverter by allowing testing and servicing near
the inverter.
To connect the strings to the Synergy Manager with MC4 connectors:
Connect the DC connectors of each string to the DC+ and DC- connectors according to the
labels on the Synergy Manager.
When connecting cables from a combiner box, ensure that the cable pairs are marked
with DC+ and DC- symbols.
