7.3. Insert the individual wires into the slots inside the cap of the end cap.

7.4. Screw the hex nut onto the cap. Use a wrench to ensure the hex nut is

screwed in all the way to the base of the cap.

WARNING

Ensure the AC trunk cable and end cap do not touch the roof by using cable

clips or tie wraps to attach the trunk cable to the PV racking. Ensure that all

cabling is located underneath the PV module.

Step 8: Connect the AC Junction Box

Connect the AC trunk cable to the AC junction box using the appropriate gland or

strain relief fitting. The AC trunk cable requires a strain relief connector with an

opening of 1.6 cm (0.6 in) in diameter.

The wires in the AC trunk cable are identified by color: L1 is sheathed in Black, L2

is sheathed in Red, Neutral is sheathed in White and Ground is sheathed in Green.

Note the Neutral/White wire is unused.

WARNING

Although the AC trunk cable includes a grounding wire, the continuous grounding

conductor or grounding washers is still required.

Step 9: Connect the PV Modules

Mount the PV modules above the micro inverters, and then connect each micro

inverter to a PV module. (The micro inverter and PV module's DC cables have two

connectors. Connect the micro inverter positive connector to the PV module

negative connector, and vice versa.)

CAUTION

Micro inverters and PV modules are installed using a one to one ratio.

POST-INSTALLATION

WARNING

Service/changes to your electrical system should be carried out only by

qualified electricians. Do not attempt to repair this product; it does not contain

user-serviceable parts. Repairs and internal servicing should only be performed

by authorized service personnel.

Commissioning and Operating

Step1. Turn on the AC disconnect or the circuit breaker for each micro inverter

AC branch circuit.

Step2. Turn on the main utility-grid AC circuit breaker. Your system will start

producing power after five minutes.

Step3. Register PV system on Darfon Solar Portal. (Monitoring System - Optional).

Depending on the strength of the signal, it can take up to 2 hours before

the monitoring system detects all the micro inverters in the PV system.

GFDI Fault

GFDI fault is defined as an unintentional, electrically conducting connection

between an ungrounded conductor of an electrical circuit and the normally

non-current-carrying conductors, metallic enclosures, metallic raceways, metallic

equipment or earth. When a Ground fault occurs, the GFDI will trigger the LED

light to show continuous Red, and the micro inverter will automatically

disconnect all conductors as a safety precaution.

If the GFDI has detected a ground fault, please contact with the installer and

follow the Operation Manual to clear this condition. Or you can contact Darfon

customer support at [email protected].
