36 Connecting the PV arrays to the Synergy Manager
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 DC wires to a Synergy Manager with DC wire terminals:
1. Thread wires with a maximum of 50 mm
conduit.
2. Route the DC wires to the DC+ and DC- terminals on the DC+ and DC- boards of the
Synergy Manager (see DC+ and DC-labels on DC boards).
CAUTION!
The DC boards have three pairs of DC terminals. Each pair is connected to a
single Synergy Unit (Left, Center and Right).
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 ().

3. Loosen the Allen screws of the DC terminals.
4. Strip the wire insulation from the end of the DC wires.
