Connecting Pv Modules To The Synergy Manager - SolarEdge SE K Series Installation Manual

48 Connecting PV Modules to the Synergy Manager
WARNING!
The inverter must be protected by an over-current protection device (a circuit
breaker or a fuse) with a maximum rating of 250 A.
Over Current Protection Device (OCPD) for the AC output is to be provided at
the time of installation. Coordination of conductor sizes with overcurrent
protection shall be in accordance with the Canadian Electrical Code, Part I.
For the exact rating of an over-current protection device, per model, refer to
Application Note:

The following wire configurations can be used to connect the Synergy Manager:
L1, L2, L3, PE wires
L1, L2, L3, N, PE wires
WARNING!
To avoid shock hazard conditions, the PE wire must be connected to the
inverter before connecting the AC wires.
AVERTISSMENT!
Pour éviter les risques d'électrocution, le fil de terre doit être connecté à
l'onduleur avant de connecter les fils CA.
Use AC line wires with a maximum of 4/0 AWG cross section conductor
Use PE wire with a maximum of 1/0 AWG cross section conductor
Use a PE wire with an outer diameter to a torque of 0.4 to 0.43"
Use copper aluminum wires with insulation rated for at least 90°C. Make sure to
consider the maximum termination temperature at both ends of the conductor and
to base the ampacity on the lower value.
CAUTION!
Over-current protection for the AC output must be provided by the installer.

Connecting PV Modules to the Synergy Manager

The Synergy Manager is designed to directly connect up to 12 PV strings or up to three
PV arrays via an external combiner box.
CAUTION!
When installing a system with more than 3 PV strings per a single Synergy Unit
(whether connected directly or via a combiner box), fuses are required. In
SolarEdge system, 25A fuses must be used (See Figure 20 and Figure 21 )
