SAFETY PRECAUTIONS
The series grid-tied solar inverters are designed and tested strictly in accordance with
relevant international safety standards. As an electrical and electronic device, all relevant
safety regulations must be strictly complied during installation, operation, and maintenance.
Incorrect use or misuse may result in：
• Injury to the life and personal safety of the operator or other people.
• Damage to the inverter or other property belonging to the operator or other people.
In order to avoid personal injury, damage to the inverter or other devices, please strictly
observe the following safety precautions.
This chapter mainly describes various warning symbols in operation manual and provides
safety instructions for the installation, operation, maintenance and use of the series grid-tied
solar inverters.

SAFETY GUIDELINES
After receiving this product, first ma ke sure that the product is well
packaged. If you have any questions, please contact the shipping
company or local distributor immediately.
Installation of PV inverters must be performed by professional
technician who has been specially trained, thoroughly read and familiar
with all the contents of this manual and familiar with the safety
requirements of the electrical system.
Do not carry out any wiring and inspection or changing components
when the power supply is applied.
Ensure that there is no electromagnetic interference from other
electrical and electronic equipment on the installation site .
Do not refit the inverter unauthorized.
All the electric installation needs to be compliance with the national or
local laws and standards.
The temperature of individual parts o r the enclosure of the inverter–
especially the heat sink may become hot in normal operation. There is a
danger of burning. Do not touch.
It must be reliably grounded before operation.
Do not open the cover of inverters unauthorized. The electrical parts
and components inside the inverter are electrostatic. Take
measurements to avoid electrostatic discharge during rel evant
operation.
The inverter must be reliably grounded.
Ensure that DC and AC side circuit breakers have been disconnected
and wait at least 5 minutes before wiring and checking.
Note: Technical personnel who can perform installation, wiring, commissioning,
maintenance, troubleshooting and replacement of the series grid-tied solar inverters
must meet the following requirements:
Operators need professional training.
Operators must read this manual completely and master the related safety precautions.
Operators need to be familiar with the relevant safety regulations for electrical systems.
Operators need to be fully familiar with the composition and operating principle of the
entire grid -tied photovoltaic power generation system and related standards of the
countries/regions in which the project is located.
Operators must wear personal protective equipment.

WHAT TO DO AFTER SCRAPPING
DELIVERY AND INSTALLATION
GRID-TIED OPERATION
Only qualified electricians are allowed to operate the inverter under the
permission of local power departments.
All electrical connections must meet the electrical standards of the
countries/regions in which the project is located.
Ensure reliable installation and electrical connection before operation.
 Do not open the cover of inverter during operation or voltage is present.
Keep the package and unit complete, dry and clean during storage and
delivery.
Please remove and install the inverter with two or more people, because of
the inverter is heavy.
Remove and instal l the inverter with appropriate tools to ensure safe and
normal operation and avoid physical injury or death. The people also need
mechanical protective measures, such as protective shoes and work clothes.
Only qualified electricians are allowed to install the inverter.
Do not put and install the inverter on or close to combustible materials.
Keep the installation site away from children and other public places.
Remove the metal jewelry such as ring and bracelet before installation and
electrical connection to avoid electric shock.
Do cover solar modules with light-tight materials before electrical connection.
Exposed to sunlight, solar modules will output dangerous voltage.
The inverter input voltage cannot exceed the maximum input voltage;
otherwise inverter damage may occur.
The positive and negative pole of solar module s cannot be grounded,
otherwise irrecoverable damage may occur.
Ensure the proper grounding of the inverter, otherwise, improper connection
or no grounding may cause stop of the in verter.
 Ensure reliable installation and electrical connection.
Do not dispose of the inverter together with household waste. The user has
the responsibility and obligation to send it to the designated organization for
recycling and disposal.

APPLICATION
The photovoltaic grid-tied power generation system consists of solar modules, grid-tied
inverter, metering devices and public grid.
Grid-tied solar inverter is the core of photovoltaic power generation system. The solar energy
can be converted into DC electric energy through solar modules and then be changed into
sinusoidal AC energy which has the same frequency and phase with the public grid by
grid-tied solar inverters, and then be fed to the grid.
The series grid-tied solar inverters are only applied in solar grid-tied power generation
system and its DC input are only composed of crystalline silicon solar modules whose
negative and positive poles are not grounded.
MAINTENANCE AND INSPECTION
SOLAR GRID-TIED POWER GENERATION SYSTEM
 Only qualified electricians are allowed to perform the mainte-
nance, inspection, and components replacement of the inverter.
 Contact with the local dealer or supplier for maintenance.
 In order to avoid irrelevant personnel from entering the mainte-
nance area during maintenance, temporary warning labels must be
placed to warn non-professionals to enter or use fence for isolation.
 Firstly disconnect all power supplies of the grid to the inverter
before any maintenance, and then disconnect the DC breakers and
wait for at least 5 minutes until the inverter is discharged before
maintenance.
 Please follow electrostatic protection norms and take correct
protective measures because of the electrostatic sensitive circuits
and devices in the inverter.
 Do not use parts and components not provided by our company
during maintenance.
 Restart the inverter after settling the fault and problem which may
affect the safety and performance of the inverter.
 Do not get close to or touch any metal conductive part of the grid
or inverter, otherwise electric shock, physical injury or death and fire
may occur. Please do not ignore the warning icons and instructions
with “electric shock”.
