Ⅱ、Safety instructions
◆Equipment
1. Please read the user manual carefully before use. Do not exceed the
rated power.
2. Before connecting the equipment, please connect the ground wire and
disconnect all load switches.
3. If the equipment fails, please cut off the power quickly and contact the
dealer.
4. If there is a fire around the equipment, the power should be
disconnected at first time,turn off the equipment and use a dry powder
fire extinguisher. Using the liquid to extinguish the fire may cause a
risk of electric shock.
5. Do not place the container filled with liquid on the top of the device so
as not to pour it into the device and cause an internal short circuit,
resulting in electric shock or fire hazard;
6. Do not open the device chassis by yourself. There is a danger of
electric shock.
7. There is high voltage inside the equipment. To avoid personal injury, if
you have any problems, please consult the dealer for professional help.
Do not repair it without authorization.
8. This series of products are Class A interference radio products.
Devices that are sensitive to electromagnetic interference (such as
transmitters, receivers, radar, and metal detectors) should not be near

this device.
Warning
Our company considers the personal safety of the customer in the most
important position. Therefore, the customer or the operator must read the
relevant steps in detail before using the device and strictly observe the usage
rules when using it. Even if all the switches are disconnected, there is still a
danger of high voltage in the equipment. Any operation that requires the device
to be moved or opened must be done by anAuthorized Technician.
Ⅲ、Transportation and storage
◆Transportation
When the goods are sent, they have been thoroughly inspected. After
receiving the goods, please check whether the packaging is damaged or not.
If there is any damage or missing items, you must notify the dealer within 7
days after receiving the goods.
◆Unpacking
To avoid damage to the equipment, special care should be taken when
moving the equipment; when unpacking the packaging material, ensure that
it is intact and stored properly for emergency use.
◆storing
After the device is received, if it will not be used within seven days, store it
in a clean, dry, room temperature (0°C to 40°C).
◆Transportation
The equipment must be kept upright and handled with care. Any fall or

violent impact can damage the equipment.

Ⅶ、Installation
1. Before wiring, make sure that all power is cut off in case of danger of
electric shock.
2. Wire preparation: first determine the length of the wire, determine the
location of the installation, reduce the length of the wire as much as possible to
reduce the power loss.
3. First connect the battery, pay attention to the positive and negative, do

not reverse. If it is reversed, the machine will be damaged and it cannot be used
anymore.
4. Connect the wires of the solar panel, pay attention to the positive and
negative poles, do not reverse; if there is sunlight, the solar controller inside the
machine will charge the battery, otherwise check the connection cable is correct.
5. Finally connect the load and then the city power line.
Warning
Installation must be performed by qualified technicians with reference to
relevant safety standards。
◆Environment
1. The equipment must be installed vertically on a horizontal shelf or on
the ground. Do not stack objects on the equipment；
2. The ambient temperature range for equipment operation is 0°C to
40°C, and the ideal temperature condition is 15°C to 25°C; the air
humidity is 0-95% without condensation; the battery life is defined at
20°C, starting from 20°C each Increasing 10°C will reduce the
expected service life by 50%.
◆Space size
1. Placement of equipment
Leave 20cm space at the top and four sides of the device to keep the
air pass unimpededly

1. Avoid direct sunlight;
2. Avoid overheating;
3. Avoid moisture and contact with liquids;
4. Avoid dust.
External protection device
The external device of the product must be equipped with a suitable circuit
breaker or fuse.
pay attention
The external connect battery box must be closer to the inverter cabinet, and
an appropriate circuit breaker must be configured.
Ⅷequipment operation
Read the equipment manual carefully before operating the equipment. The
equipment should be in charge of the professional to ensure the normal
operation of the equipment.
Danger
1. After the inverter connected to the mains (means city power), the
inverter output may be in a live state (means will have electricity), even if
the inverter is not manually turned on.
2. If the inverter output short circuit or overload, should immediately turn
it off, cut off the power, check the load troubleshooting and then start the

inverter again to work.
3. After the installation of the inverter is completed, be sure to install the
terminal cover to prevent the rat from entering the inverter to cause a short
circuit board and to damage the machine.
