Chapter 4: Connecting PV Modules and AC to
the Synergy Manager
This section describes how to connect the inverter to the PV modules and to the AC.

Grid Connection Guidelines

In most countries, three phase inverters require neutral connection. In some countries,
three phase inverters can be connected to delta grids along with multiple single phase
inverters.
NOTE
If local regulations permit, the connection of Neutral is optional in a 4-wire
system of three phase inverters.
If local regulations permit, the connection of Neutral is optional in a 4-wire system of
three phase inverters.
Prior to system installation, refer to the following documentation:
The conduits, hubs and fittings must be suited for field wiring systems.
The hubs and other fittings must comply with UL514B.
Use the conduit and wiring appropriate for the installation location per the NEC.
Outdoor installations must use components that are rated NEMA 3R or higher.
