Surge Suppression
Lightning does not actually need to strike the equipment or building where the
PV system is installed to cause damage. Often, a strike nearby will induce voltage
spikes in the electrical grid that can damage equipment. Artificial spikes such as
those induced by electric motors starting up can also cause damages to the
equipment.
The micro inverters have integral surge protection built-in; however, if the surge
has sufficient energy, the built-in protection in the device would be exceeded and
the device could potentially be damaged. Therefore, external surge protection
MUST be installed as part of any solar installation.
WARNING
When installing a surge protection device (SPD), one MUST follow the original
manufacturer’s instructions on how to install the SPD properly. Incorrect
installation of the SPD may still cause damages to the micro inverters. If the
installation site is known for unstable or heavy surges, then it is the
responsibility of the installer to make sure the SPD chosen can adequately
protect the micro inverters.
The following SPD specification is the minimum protection level that is required

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 Micro Inverter
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 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.
Parts and Tools
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.

CAUTION
Each AC branch circuit must be
protected by a dedicated circuit
breaker of 30A or less if using 10 AWG trunk
cable, or 20A or less if using 12 AWG trunk cable.
AC Trunk Cable
There are different types and options for AC trunk cables. Depending on the
orientation of the installation, the AC trunk cable can be in portrait or landscape
format. Trunk cables can also consist of three pins (three wires) or four pins (four
wires). Currently the four-pin AC trunk cable is used.

Grounding Options
Option 1: Integrated Grounding
Integrated grounding eliminates the need to install Grounding Electrode
Conductor (GEC) to each G320 by completely isolating the internal DC circuit
from the AC circuit and ground. DC ground faults are detected on either the
positive and/or negative conductors of the DC circuit by a Ground Fault Detection
Interrupter Insulation Monitor (GFDI IM). If the GFDI IM detects a ground fault
has occurred to the PV input, the micro inverter will automatically disconnect all
conductors and cease supplying output power. In accordance with NEC 690.35 ,
installers can build ungrounded arrays where only an Equipment Grounding
Conductor (EGC) is required to connect or bond non-current carrying metal
equipment together. The EGC grounding process is completed via the grounding
connection of G320 4-wire AC cable to the AC trunk cable. The PV module will
still need to be grounded according to the module manufacturer’s instructions.
Option 2: GEC Grounding
Although the G320 offers integrated grounding (UL 1741 certified), it also comes
with a grounding terminal clip for any localities that do not accept integrated
grounding. The micro inverter manufacturer will not be held responsible for
improper installations that do not have local AHJ and/or Utility operational
approval.

As indicated in the diagram below, the array GEC can be installed either in series
or in parallel.
Micro Inverter Layout
Using the installation map template in this manual, draw out the layout of the
array and have it readily available during the installation of the micro inverters to
record micro inverter location.
Draw the layout of the solar panels in the installation map template like the
sample image shown below. When a micro inverter is fastened in its position,
then the secondary serial number sticker on the DC side can be peeled off the
micro inverter and adhered to the installation map template where the actual
position on the roof would correspond to the same panel on the layout drawing.
Note: Tracking micro inverter location by serial number is key for data monitoring
and warranty servicing.
Surge Protection
The micro inverters have integral surge protection built-in; however, if the surge
has sufficient energy, the built-in protection in the device would be exceeded and
the device could potentially be damaged. Therefore, external surge protection
MUST be installed as part of any solar installation.
Please refer to the “Surge Suppression”section on pages 2 and 3 on
specifications for appropriate surge protection.

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.
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.
Step 3: Lay Out the AC Trunk Cable
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.

WARNING
Correct AC grounding and short circuit protection must be provided to ensure
operational safety.
Step 6: Connect the 1T AC trunk cable
6.1. Connect the 1T AC trunk cable (with BMC cap) to another 1T AC trunk cable.
Ensure the connection is secure and locked into place by listening to “click”
sounds when both lock pins are fully inserted.
WARNING
Correct AC grounding and short circuit protection must be provided to ensure
operational safety.
6.2. Repeat for all 1T AC trunk cable in the AC branch circuit.
6.3. After connect all 1T AC trunk cables, please use the BMC end cap-male to
connect the left side of 1T AC trunk cable. Please ensure the connection is
secure and locked into place by listening to “click”sounds when both lock
pins are fully inserted.
Step 7: Terminate the Unused End of the AC Trunk Cable
7.1. Strip 10mm (about 0.5in) of the outer sheath from the end of the AC trunk
cable.
7.2. Each end cap has four parts: the sealing nut, clamp ring, seal and cap. Slide
the sealing nut, clamp ring and then the seal onto the AC trunk cable.

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.
