PRE-INSTALLATION

Thank you for choosing G640 micro inverter as a key component to your solar

The Micro Inverter

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

G640 micro inverters.

PV System Layout

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 G640 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;

Parts and Tools

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.

Equipment for Micro Inverter Installation

• Sealing caps (for unused connectors)

• AC trunk cable

• AC connector removal tool

• End Caps (used at the end of AC cable)

Equipment for Monitoring System Installation

• Data Logger (Includes AC Adapter, RS485 Connector, Wall-Mounted Frame

and Ethernet Cable)

• PLC Box (Includes RS485 Connector)

• Red/Black Wiring for RS485

Other Tools/Equipment

• Outdoor-rated AC junction box(es)

• Cable clips and/or tie wraps

• Gland/strain relief fittings (on per AC junction box)

Compatibility and Capacity

• Torque wrench & sockets for mounting hardware

• Adjustable/open-ended wrench (for end caps)

G640 micro inverters are electrically compatible with PV modules that have a

voltage range of 24V to 60V and a maximum wattage of 350W although 320

watts is considered optimal. Please refer to the 'Compatible PV Module

Calculator' on the website at www.darfonsolar.com to verify the PV module is
