4. Indicators and Meanings
COM: Yellow communication indicator. Indicates device IP addresses. They are coded and
displayed following the Morse code and display interval in the table below. IP addresses are
displayed as 00 to 99 cyclically.
RUN:Green running indicator. It is not on in initial mode. After the converter is connected to a
grid and runs, this indicator flashes at an interval of 120 ms. In normal mode, this indicator is
steady on. In fault mode, this indicator is off.
FAULT: Red fault indicator. In non-fault mode, this indicator is off. If the converter does not
receive CAN data within 30 seconds, it reports a communication fault, and this indicator is
steady on. In case of a fault, this indicator flashes according to the Morse code and display
interval in the table below based on fault types. Error code range: 00~99.

6. Transport, Storage and Installation
Transport
Load and unload the converter with caution to avoid deformation, break or other problems.
Storage
If the converter is not put into use immediately, store it following the requirements below:
1. Put the machine and accessories back into the box, seal the box with tape, and put the box
in a clean and dry place to avoid dust and vapor entering the box.
2. Ensure that the storage place is free of hazardous gases, flammables/explosives, and
corrosives. Keep the temperature in the range from -25°C to 60°C and relative humidity in
the range from 0 to 95%.
3. After a long-term storage, invite a professional to test the converter before using it.

Installation
Installation precautions
1. Ensure that the installation position is firm enough to support the weight of the converter and
force generated by external vibration.
2. Ensure that the installation position and height of the converter facilitate wiring, operation,
and maintenance.
3. Do not install the converter on flammable wall or in space containing flammable gases and
materials.
4. Keep the converter vertically installed to facilitate heat dissipation. Do not lay the converter
horizontally, tilt or upside down.
5. The converter is rated IP54 and suitable for indoor and outdoor installation.
6. The installation altitude should not exceed 2000 m, with ambient temperature in the range of
-25°C~50°C. When the ambient temperature exceeds 35°C, the output power of the
converter is reduced.

7. The relative humidity of the installation place should not exceed 95%; otherwise, vapor may
corrode the converter and cause damage to internal components.
8. It is of vital importance to ensure good ventilation of the converter. Do not install the
converter in a sealed box; otherwise, the converter fails to work properly or is damaged.
9. Exposure to sunlight, rain or snow directly affects the service life of converter. If such
impacts are unavoidable, properly cover the converter to ensure optimal running state.
Installation(Upright)
If the converter installed on the flat roof, 4 bulgy bolts are needed M8*60.The user can use

7. Wiring
Warning
1. All wiring steps must comply with electric standards of a country or region where the
installation takes place.
2. Follow these rules: rules related to input power grid; safety instructions related to PV
strings.
3. Converter connection with a grid must be licensed by local electric power department before
qualified electric technicians implement wiring. Before the converter is connected to a grid,
confirm that grid voltage and frequency are within the output range of the converter;
otherwise, contact local grid company.
4. Remember that the converter uses bidirectional power supply mode. Technicians must take
protective measures before wiring.
5. Cables must be connected firmly with intact appearance, proper insulation and proper
specifications.
6. Do not add any load between the converter and a circuit breaker.
7. Though the PV input of the converter has been embedded with a protector, the converter
must be equipped with proper DC circuit breakers or other external protectors.
CAUTION–Configure two-channel PV input for the converter. The maximum current
of each channel is 14A. You are advised to select two 14A 1000VDC circuit breakers
(complying with UL standard requirements) as external protectors. That is, each channel is
allocated a protector.

The current protection value recommended for each PV input is calculated based on the
connection mode where 260W PV panels are connected in a way that 22 panels are
connected in series to form a string and two strings are connected in parallel.
In other cases, the current of DC circuit breakers needs to be determined according to PV
panel specifications and string methods selected for engineering installation. For details,
consult related manufacturers.
8. Though the AC output of the converter has been embedded with a protector, the converter
must be equipped with properAC circuit breakers or other external protectors.
CAUTION–The maximum current for the AC output is 40A. You are advised to select
a 40A 208V~240V AC circuit breaker (complying with UL standard requirements) as an
external protector.

Installation Precautions:
Improper operation or failure to operate the converter as instructed may cause danger to
users and result in major hardware damage, even property loss or personal injury. Please read
this manual carefully before operation and observe the following safety instructions strictly.
Before operation, disconnect the converter from a grid, and avoid touching any terminal or
conductor connected with the grid and PV input circuit. Any contact between the converter and
grid may cause fire or electric shock.
Static discharge of internal components may result in irrevocable damage to the converter.
When operating the converter, please strictly observe the ESD protection specifications.
Electric shock and fire may cause a risk of leakage. Before PV and grid connection, ensure
that the converter has been safely grounded.
To ensure that the converter can be safely disconnected when loaded, configure
independent circuit breakers for each converter as their protectors.
Any operation on the converter must be carried out by qualified electric technicians.
The converter may be maintained only by professionals; PV input port channels 1~2.
All safety instructions and precautions in the installation guide must be followed.

2.Loosen the nut on the DC connector, and take out the plug.
3.Peel 10 mm insulation layer from the DC cable.
4.Use a crimp to press the exposed cable core (about 10 mm) to the DC terminal (as shown in
①). Note that the shapes of the positive and negative metal terminals are different.
5.Penetrate the cable through the nut (as shown in ④and ③). Since positive and negative
terminals have different shapes, DC connectors vary accordingly. For details, see the
following figures.
6.Install ②and ③components into the DC connector in the direction of the arrow, and pull the
cable outward gently to confirm that the terminal has been fixed into the connector.
7.Tighten the nut (as shown in ④), and pull the cable outward to confirm the connection again.
