Read This First
Dear customer, thank you for choosing the G3 Plus series micro inverter from TSUN. We hope
you will find our products meet your needs for renewable energy. Meantime, we appreciate
your feedback regarding our products.
A solar micro inverter, or simply micro inverter, is a plug-and-play device used in
photovoltaics, that converts direct current (DC) generated by a single solar module to
alternating current (AC). The main advantage is that small amounts of shading, debris or, snow
lines on any single solar module, or even a complete module failure, do not disproportionately
reduce the output of the entire array. Each micro inverter harvests optimum power by
performing maximum power point tracking (MPPT) for its connected module. Simplicity in
system design, lower amperage wires, simplified stock management, and added safety are
other factors introduced with the micro inverter solution.
This manual contains important instructions for G3 Plus micro inverters and must be read in its
entirety before installing or commissioning the equipment. For safety, only qualified
technicians, who have received training or have demonstrated skills can install and maintain
this micro inverter under the guide of this document.
Important Safety Information

System Introduction
The G3 Plus micro inverter is used in grid-tied applications, comprised of two key elements:
 G3 Plus Micro inverter.
 TSUN Monitoring System.
The micro inverter converts the DC electricity generated by solar panels into AC electricity
which is in accordance with the requirements of the public grid and sends the AC into the grid,
reducing the load pressure of the grid.
The micro inverter is integrated with the Wi-Fi module and connects to the home Wi-Fi router
directly. Users can monitor the power generation of the system by TSUN Monitoring App.

2402MHz—2480MHz(EIRP ＜10dBm)
Micro inverter Installation
Pre-installation Check
Check the Package
Although TSUN’s micro inverters have surpassed stringent testing and are checked before they leave
the factory, it is uncertain that the micro inverters may suffer damage during transportation. Please
check the package for any obvious signs of damage, and if such evidence is present, do not open the
package and contact your dealer as soon as possible.
Check the Installation Environment and Position
When choosing the position of installation, comply with the following conditions:
To avoid unwanted power derating due to an increase in the internal temperature of the inverter,
do not expose it to direct sunlight.
To avoid overheating, always make sure the flow of air around the inverter is not blocked.
Do not install in places where gasses or flammable substances may be present.
Avoid electromagnetic interference that can compromise the correct operation of electronic
equipment.
It’s recommended to install micro inverter on structures underneath the photovoltaic modules so
that they work in the shade without touching the rooftop.
Use a mobile phone to check the Wi-Fi signal strength at the micro inverter installation position. If
the Wi-Fi signal is weak, try to install the micro inverter in another place with a better signal, or
move the Wi-Fi router or repeater closer.
Installation Steps
DANGER
·Only qualified personnel should install, troubleshoot, or replace G3 Plus micro inverters or
the cable and accessories.

·Unauthorized removal of necessary protections, improper use, incorrect installation and
operation may lead to serious safety, and shock hazards or equipment damage.
·Be aware that installation of this equipment includes the risk of electric shock.
Step 1. Fix the micro inverter.
DANGER
·Do not install the equipment in adverse environment conditions such as flammable,
explosive, corrosive, extremely high or low temperature, and humid.
WARNING
·Choose the installation location carefully and adhere to specified cooling requirements.
Micro-

Use a Connector Protective Cap to make sure the unused AC connector to be closed.
Step 4. Connect the AC end cable of each cable section
DANGER
·Do not install the AC junction box without first removing AC power from the system.
·To prevent electrical hazards, make sure the micro-
inverter system is disconnected from the
home distribution network and the AC breaker is open.
WARNING
·Ensure that all AC cables are correctly wired and that none of the wires are pinched or
damaged.
·Use AWG 12 (4 mm²) cable for AC end cable.
CAUTION
·The installation technician is responsible for selecting a kind of AC cable and connecting the
micro-inverter system to the home distribution network correctly.
·The AC connectors may be provided by different suppliers. The port definitions are sub
ject to
actual objects.
Take out the AC connector from the package. Separate the AC connector as shown below.

Step 5. Connect the DC cable
DANGER
·When photovoltaic panels are exposed to light, it provides a DC voltage to the inverter.
WARNING
·Ensure that all DC cables are correctly wired and that none of the wires are pinched or
damaged.
·The maximum open circuit voltage of t
he PV module must not exceed the specified
maximum input DC voltage of the micro inverter.
CAUTION
·If the DC cable is too short for installation, use a DC Extension Cable to connect PV modules
to the micro inverter.
·Use MC4 compatible DC connectors in the inverter side of the
DC extension cable, or get the
DC connectors from TSUN.
·Contact PV module manufacturers for the requirements of the
DC connectors in the module
side of DC extension cable.
Install the PV modules and connect the DC cable to the micro inverter.
Step 6. Make an installation map
CAUTION
·If there is more than one installation site, please make the installation map separately and

G3 Plus Microinverter
V1.0
-

-
give a clear description of the installation site.
·The row of the table corresponds to the shorter side of the
PV module and the column of the
table corresponds to the longer side of the PV module. The direction i
n the upper left corner
means the actual installation orientation.
Take out the SN labels and installation map from the package. Paste the SN labels on the installation
map below and complete the information on the solar plant.
Step 7. Start the System
DANGER
·Only qualified personnel should connect this system to the utility grid.
CAUTION
·Do not connect the micro inverter(s) to the grid, nor energize the AC circuit(s) until you have
completed all installation procedures and have received prior approval from the electricity
utility company.
While installation is all finished, turn on the main utility-grid AC circuit breaker. Your system will
start producing power after about a two-minute wait time.
The LED will flash green and red on startup. The LED definition is shown below:
Status Indicates
Flashing Green (0.2-0.8 ) Working normally

Remote Active Power Control
In some countries, it might be required that the generating plants should be equipped with a logic
interface (input port) to cease the output of active power or limit active power to a regulated level.
This logic input can be the RS485 port, Ethernet port, and so on. TSUN micro inverter provides an
extra power control device that contains an RS485 port for this remote active power control. For
more information, refer to the “User Manual of TSUN power control device”.
Self-Test Function for Italy
