Before using the inverter, please read all instrucons and cauonary
markings on the unit and manual. Put the instrucons where you can
take them easily. The inverter of us strictly conforms to related safety
rules in design and test. Local safety regulaons shall be followed during
installaon, operaon and maintenance. Incorrect operaon work may
cause injury or death and damage to the inverter and other operator or a
third party. To avoid injury and damage to the inverter and other opera-
tor,please follow the safety precauons.
Target Group
Inverters must be installed by professional electrical engineers who
have obtained relevant qualicaons.

1.2 Safety Precauon
1.1 Symbols Used
• Installaon and maintenance of inverters must be performed by
qualied personnel, in accordance with local electrical standards,
wiring regulaons and requirements of local power authories.
• To avoid electric shock, DC input and AC output of the inverter must
be terminated at least 10 minutes before performing any installaon
or maintenance.
Symbol Description
Danger of high voltage and electric shock!
Only qualied personnel may perform work on the inverter.
Danger of high voltage. Residual voltage in the inverter need
5 mins to discharge, wait 5 mins before operaon.

• The temperature of some parts of the inverter may exceed 60°
• during operaon,do not touch the inverter during operaon to
avoid being burnt.
• Ensure children are kept away from inverters.
• Don’t open the front cover of the inverter. Apart from performing
work at the wiring terminal, touching or changing components
without authorizaon may cause injury to people, damage to
inverters and annulment of the warranty ropriate measures to avoid
electric shock.
• Ensure the output voltage of the proposed PV array is lower than
the maximum rated input voltage of the inverter; otherwise the
inverter may be damaged and the warranty annulled.
• When exposed to sunlight, the PV array generates dangerous high
DC voltage. Please operate according to our instrucons,or it will
result in danger to life.
• Don’t insert or pull the terminals when the inverter is running.

The three-phase grid-ed PV inverter converts the DC generated by PV
panels into three-phase alternang currentand is delivered to the grid.
This series inverter is an important part of PV system and it is suitable
for household use, commercial use, shery use, agricultural use and other
scenarios.
This series inverter is suitable for TN-S, TN-C, TN-C-S and TT grid system.

3.1 Upack and Check
Complete test and strict inspecon shall be done before the inverter is
sent out. When receiving the inverter, check that the packing materials
are intact. Aer unpacking, examine the PV inverter and its ngs for
damage and check that the deliverables are complete.

Inverter body label. The following is only for reference, specic please in
kind prevail!
If the inverter is not used immediately, please keep the inverter in a
specic environment according to the
following requirements.
• Do not unpack the inverter and put desiccant in the original box if
the PV inverter is unpacked.
• Store temperature range: -25°C~+60°C; Relave humidity range:
0~100%.
• Don’t posion the inverter leaning forward, excessively leaning
backward, lng laterally, or upside down.
• Ensure that qualied personnel inspect and test the inverter before
use if it has been stored for a long me
t
Contact your dealer immediately if there is any issue found during
operation.

Aer checking the outer packing, move the PV inverter to the designated
installaon posion horizontally.
a. The storage inverter protecon class is IP65 and can be mounted
indoors or outdoors.
b. To ensure opmum operaon and long service life, the ambient
temperature must be below 50°C.
c. Do not install the inverter in a rest area since it will cause noise during

Step 1. Install the mounng bracket
4.2 Mounng
1.The walls must be leproof and non-ammable
materials,othewise there is a re risk.
2.Before drilling holes ,check whether there are electric power
pipes buried in the walls to avoid risks.
DANGER
1 ) Use a horizontally ruler to mark the posion of the 3 holes on the wall.
Refer to Step 1. And drill 3 holes, 10mm in diameter and 60 mm in deep.
Refer to Step 1 and Step 2.
2) Knock the expansion screw kit into the hole together with a hammer.
Refer to Step 3.
Note: Do not remove the nut unit.
3) Aer ghtening 2-3 buckles, the expansion bolts are ght and not
loose, and then unscrew the bolts, spring washer, gasket. Refer to Step 3.
4) Install the bracket on the wall,the bracket screw is pointed at the
expansion tube on the wall, then install the gasket and ghten screw.
Refer to Step 4.

15
Step 2. Install the inverter.
Install the inverter on the bracket accurately and ghten the screws at
both sides, as shown in Step 5 and Step 6.
To prevent damage of the inverter, please hang the inverter on the
bracket and conrm the reverse,do not loosen the handle until the
inverter is xed

System Connecon
According to the EN50178 requirement, the right side of the device has
a protecve grounding connecon. Be sure to connect the protecon
ground cable to this port when installing the inverter. The user can
perform the ground connecon according to the on-site condion
Electrical Connecon

5.1 Grounding

17
If the positive pole or negative pole of the PV array is required to be
grounded, then the inverter output (to AC grid) must be isolated by
transformer in accordance with IEC63109-1,-2 standards.
CAUTION
According to regulations,the secondary protection grounding can’t
replace the PE terminal connection of the AC cable. Ensure that
both are grounded reliably. Otherwise,fatal injury can occur due to
the high voltage.
