PRE-INSTALLATION

Thank you for choosing G320 micro inverter as a key component to your solar

power system. Review and follow the instructions in this section before installing

G320 micro inverters.

The optimal PV array layout will need to be planned before installation. The

layout/plan will affect the wiring and cabling schemes and will need to be

adjusted accordingly. The layout will also need to account for the constraints of

the distance between each PV module due to the connectors on the trunk cable

and the distance between the micro inverters and PLC box.

• The maximum cable distance from the PLC box to the farthest G320 is 50

meters (164 feet).

• It is ideal to tap power from the center of the circuit, so 2 segments of 9 and

10 modules (total 19) for each circuit. This maximizes the communication

signal strength to the PLC box.

• The use of a RS485 specific cable is recommended, such as Belden 3105A;

however, any twisted pair cable can be used, such as CAT5, with some

degradation of signal and distance.

This section provides a list of equipment and tools needed for installing and

setting up the PV system. Please refer to the Equipment and Parts section for

components associated with the micro inverter.
