1.2 Safety Instruction
Installation and maintenance of inverters must be performed by qualified personnel, in accordance with
local electrical standards, wiring regulations and requirements of local power authorities.
The temperature of some parts of the inverter may exceed 60℃ during operation, do not touch the
inverter during operation to avoid being burnt.
Ensure children are kept away from inverters.
Take appropriate measures to avoid electric shock.
Don’t open the front cover of the inverter. Apart from performing work at the wiring terminal,
touching or changing components without authorization may cause injury to people, damage to
inverters and annulment of the warranty.
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 instructions, or it will result in danger to life.
Don’t insert or pull the terminals when the inverter is running.
After the inverter is powered off, the remaining electricity and heat may still cause electric shock and
body burns. Do not touch parts of inverter for 10 minutes after disconnection from the power sources.
Danger of high voltage!
Only qualified personnel may perform work on the inverter.
Grounding terminal
1.1 Symbols Used
Safety Symbol Description
Residual voltage exists after the inverter is powered off. It
takes 5 minutes for system to discharge to a safe voltage.
Danger of hot surface
Don’t dispose of the inverter with the household waste.
Do not disconnect under load!
5 mins
Environmental Protection Use Period
Refer to the operating instructions
The sign of caution stick on inverter.
Do not disconnect with load, otherwise there will be
danger of fire.
The three-phase grid-tied PV inverter converts the DC generated by PV panels into three-phase
alternating current and is delivered to the grid.
This series inverter is an important part of PV system and it is suitable for household use,
commercial use, fishery use, agricultural use and other scenarios.

DANGER
After checking the outer packing, move the PV inverter to the designated installation position horizontally.
CAUTION
1. Please place the inverter horizontally on the foam or other soft pads and
ensure that the ports are free of load-bearing pressure to avoid inverter
damages or scratches.
2. The inverter is heavy, be careful to prevent the inverter from slipping
and hurting the operator when moving the inverter.
4.1 Selecting the Mounting Location
a. The storage inverter protection class is IP65 and can be mounted indoors or outdoors.
b. To ensure optimum operation and long service life, the ambient temperature must be below 50℃.
c. Do not install the inverter in a rest area since it will cause noise during operation.
d.The inverter carrier must be fire-proof. Do not mount the inverter on flammable building materials.
e. Ensure that the wall meets the requirements of the inverter installation.
f . Product label and warning symbols shall be clear to read after installation.
g. The installation height should be reasonable and make sure it is easy to operate and view the display.
h. Please avoid direct sunlight, rain exposure, and snow cover.

DANGER
Step 1. Install the mounting bracket Step 2. Install the inverter.
Install the inverter on the bracket accurately and tighten the screws at both sides, as shown in Step 5 and
Step 6.
1.The walls must be fireproof and non-flammable materials, othewise there
is a fire risk.

1 ) Use a level gauge to set braket horizontally, and then mark the position of the 3 holes on the wall.
Refer to Step 1. And drill 3 holes,10mm in diameter and 60 mm in depth. 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) After tightening 2-3 buckles, the expansion bolts are tight 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 tighten screw. Refer to Step 4.
System Connection
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.
WARNING
5. Electrical Connection 5.1 Grounding
Electrical Connection Electrical Connection
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.
Step2.Insert the exposed core wires into the crimping areas of the OT terminal and crimp them
using hydraulic pliers.
Step3.Remove the ground screws from the ground points.
Step1.Remove an appropriate length using a wire Stripper.
According to the EN50178 requirement, the right side of the device has a protective grounding connection.
Be sure to connect the protection ground cable to this port when installing the inverter.
The user can perform the ground connection according to the on-site condition.
