Read This First
Dear customer, thank you for choosing the G3 Plus series microinverter 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 microinverter, or simply microinverter, 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 microinverter 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 microinverter solution.
This manual contains important instructions for TSOL-MS2000/MS1800/MS1600
microinverters 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 microinverter under the guide of this
document.

the factory, it is uncertain that the microinverters may suffer damages 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 microinverter 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 better signal, or
move the Wi-Fi router or repeater closer.
Installation Steps

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 into the home distribution network correctly.
·The AC connecters may be provided by different suppliers. The port definitions are subject to
actual objects.
Take out the AC connector from the package. Separate the AC connector as shown below.
Get the AC cable through the shell of AC connecter and connect the cable to the right port.
The definition of the port is shown below:

DC
connectors form TSUN.
·Contact PV module manufacturers for the requirements of DC connectors in the module
side
of DC extension cable.
Install the PV modules and connect the DC cable to the microinverter.
Step 6. Make an installation map
CAUTION
·If there are more than one installation site, please make the installation map separately and
give a clear description about the installation site.

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:

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 microinverter provide a extra
power control device which contains a RS485 port for this remote active power control. For more
information, refer to the “User manual of TSUN power control device”.

Maintenance Guide
Routine Maintenance
Only authorized personnel are allowed to carry out the maintenance operations and are
responsible for reporting any anomalies.
Always use the personal protective equipment provided by the employer when carrying out
maintenance.
During normal operation, check that the environmental and logistic conditions are appropriate.
Make sure that the conditions have not changed over time and that the equipment is not exposed
to adverse weather conditions and has not been covered with foreign bodies.
DO NOT use the equipment if any problems are found, and restore the normal conditions after
the fault has been corrected.
Conduct an annual inspection on various components, and clean the equipment with a vacuum
cleaner or special brushes.
Firmware version can be checked by using the monitoring system.
Always de-energize the AC branch circuit before servicing.
Do not attempt to dismantle the Micro-inverter or make any internal repairs! In order to
preserving the integrity of safety and insulation, the Micro inverters are not designed to allow
internal repairs!
Maintenance operations must be carried out with the equipment disconnected from the grid (AC
power switch off) and the photovoltaic modules shaded or isolated, unless otherwise indicated.
For cleaning, DO NOT use rags made of filamentary material or corrosive products that may
corrode parts of the equipment or generate electrostatic charges.
Avoid temporary repairs. All repairs should be carried out using only genuine spare parts.
Storage and Dismantling
If the equipment is not used immediately or is stored for long periods, check whether it is
correctly packed. The equipment must be stored in well-ventilated indoor areas that do not have
characteristics that might damage the components of the equipment.
Take a complete inspection when restarting after a long time or prolonged stop.
Please dispose the equipment properly after scrapping, as component parts are potentially
harmful to the environment, in accordance with the regulations in force in the country of
installation.
