Read This First
Dear customer, thank you for choosing the Balcony 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 Balcony microinverters and must be read in
their 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.
Important Safety Information
During installation, testing, and inspection, adherence to all the handling and safety
instructions is mandatory. Failure to do so may result in injury or loss of life and damage to the
equipment.
Product Label

System Introduction
The Balcony microinverter is used in grid-tied applications, comprised of two key elements:
 Balcony Microinverter.
 TSUN monitoring system.
The microinverter 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.

Microinverter Installation
Pre-installation Check
Check the Package
Although TSUN’s microinverters have surpassed stringent testing and are checked before they leave
the factory, it is uncertain that the microinverters 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 microinverter on structures underneath the photovoltaic modules so
that they work in the shade.

Use a mobile phone to check the Wi-Fi signal strength at the installation position. If the Wi-Fi
signal is bad, try to install the microinverter in another position or move the Wi-Fi router.

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 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
TSUN microinverter and TSUN monitoring system provide a Self-test function for the Italy market.

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! To preserve 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 of the equipment properly after scrapping, as component parts are potentially
harmful to the environment, following the regulations in force in the country of installation.
