INSTALLING THE MICRO INVERTER

The following sections list steps on how to install the G320 micro inverter onto

standard PV racking.

Installing onto a PV Racking System

Step 1: Measure the AC Service at the Site

Measure service entrance conductors to

confirm AC service at the site. Verify the AC

voltages at the electrical utility connection

and at the junction box for each AC branch

circuit are within the ranges.

Step 2: Install the AC Branch Circuit Junction Box

2.1. Mount the adapter plate to a

suitable location on the PV

racking system (typically at the

end of a row of modules). The

adapter plate must be installed

with an appropriate junction

box.

Step 3: Lay Out the AC Trunk Cable

L1 to neutral

106 to 132VAC

L2 to neutral

106 to 132VAC

2.2. Connect the open wire end of the AC

interconnect cable into the junction

box using an appropriate gland or

strain relief fitting. The AC

interconnect cable requires a strain

relief connector with an opening of

3/8 inches in diameter.

Place the AC trunk cable at the required location. Align the T-branch connector to

the position where the micro inverter will be installed. Then secure the cable on

either side of the rack using cable clips or tie wraps.

Note the maximum pitch distance is 1050mm when modules are in portrait mode

and 1700mm when in landscape mode.

Step 4: Attach the Micro Inverter to the PV Racking

4.1. Note the approximate centers of each PV module on the PV racking.

4.2. Evaluate the location of the micro inverter against potential collection of

moisture or water.

4.3. Evaluate the location of the micro inverter with respect to the DC junction

box and the PV module frame.

4.4. Align the G320 so that the holes on the mounting bracket are above the slot

opening on the PV racking and secure the micro inverter to the PV racking

with screws.

CAUTION

Ensure that the inverter does not obstruct the PV module frame or

stiffening braces. Ensure the micro inverter's AC connector can easily reach the

T-branch connector.

Step 5: Ground the Micro Inverters

[Option 1]: Integrated Grounding. Go to step 6. No additional grounding is

needed.

[Option 2]: GEC Grounding. Unscrew the

top of grounding clips on the micro

inverters. Run the grounding electrode

conductor to each grounding clip on the

micro inverter and then to the junction

box. After laying out the grounding

conductor, secure the top of the

grounding clips back onto the micro

inverters.
