3.2 Identifying the Inverter
You can identify the inverter using the type label. Information such as serial number
(Serial No.) and type of the inverter, as well as device-specific characteristics are
specified on the type label. The type label is on the right side of the enclosure.
4 Mounting
DANGER!
Danger to life due to potential fire or electric shock.
Do not install the inverter near any inflammable or explosive items. The inverter will
be directly connected with high voltage power generation device. The installation
must be performed by qualified personnel only in compliance with national and local
standards and regulations.
CAUTION!
Danger of burn injuries due to hot enclosure parts.
•Install the inverter so that it cannot be touched inadvertently.
Risk of injury due to the heavy weight of the inverter.
•Take the inverter's weight of approx. 16 kg into account for mounting.
4.1 Selecting the Appropriate Mounting Location
Consider the following points when selecting where to install:
• The mounting method and location must be suitable for the inverter's weight and
dimensions.
• Mount on a solid surface. But do not mount the unit on plasterboard walls or
similar in order to avoid audible vibrations for the inverter can make noises when in
use.

5/ 34
• Vertical installation or tilted backward by max. 30 degree is allowed.
• Never mount the device with a forward tilt, horizontally or even upside down
• For the convenience of checking the LCD display and possible maintenance
activities, please install the inverter at eye level.
• The ambient temperature of installation site should be between -20 °C and +55 °C
(between -4 °F and 131 °F).
• Install the inverter directly exposes to strong sunshine is not recommended, the
excess heating might lead to power reduction.
• Provide better ventilation for the inverter to ensure that the heat is dissipated
adequately.
•The site altitude of installation should be below 1000m above sea level; more than
1000m above the sea level will cause derating.
4.2 Mounting the Inverter with Wall Mounting Bracket
1. Use the wall mounting bracket as a drilling template and drill the holes for the
screws.
2. Fix the wall mounting bracket to the wall using appropriate screws (diameter min.

6/ 34
6 mm, max. 8 mm) and washers (outer diameter min. 12 mm, max. 24 mm).
3. Hang the inverter to the mounting bracket and ensure the slot is fitted on the
bracket.
4. Check to ensure the inverter is correctly seated. Make sure to lock it with the
safety-lock screws on both sides to ensure the inverters, see the figure below.)
5 Electrical Connection
Notes:
1. After the inverter has been installed in its fixed position, the electrical connection to the unit
can be established.
2. Make sure Max. Open Voltage and short-circuit current of the each PV strings accord with the
Spec.
3. Choose the appropriate cable width for AC/DC wire.
4. To connect the inverter, the AC and DC sides must be disconnected from all power sources
and secured against being inadvertently switched back on.
5. Before connecting the inverter to PV arrays and public grid, make sure the polarity is correct.

Female side connector(F)
Male side connector(M)
Assembly Instructions:
1. Adjust the striper stopper and put the cable in corresponding notch to strip the
length of 12mm. Please refer to the following figures.
2. Insert striped cable into contact barrel and insure all conductor strands are
captured in the contact barrel.
3. Compress them together with the crimping pliers.
4. Insert contact cable assembly into back of male and female connector. A “click”
should be heard or felt when the contact cable assembly is seated correctly. Then
turn the cap to the coupler. Please refer to the following figures.

6 System Diagram
The typical connection diagram for the entire PV system is shown in the following
figure.
1. PV Panel: Provide DC power to inverter
2. Inverters: Converts DC (Direct Current) power from PV panel(s) to AC (Alternating
Current) power. Because Inverter is grid-connected it controls the current amplitude
according to the PV Panel power supply. Inverter always tries to convert the
maximum power from your PV panel(s).
3. Connection system: This “interface” between Utility and PV-Inverter may consist of
electrical breaker, fuse and connecting terminals. To comply with local safety
standards and codes, the connection system should be designed and implemented by
a qualified technician.
4. Utility: Referred to as “grid” in this manual, i.e. the way your electric power
company provides power to your place. Please note that Inverter can only connect to
low-voltage systems (namely, 220, 230VAC, 50Hz).

Product Overview
7.1 Overview of Controls and Displays

17 / 34
There are four function keys on the front panel (from left to right): Esc, Up, Down,
Enter.
The keypad is used for:
Scroll the displayed parameter(Up and Down keys);
Accessing and modifying the adjustable parameters (Esc and Enter keys).
7.2Commissioning
After completing the mechanical and electrical installation, the inverter is put into
operation.
1. Switch on the DC and AC breakers.
The inverter starts up automatically when the power from PV generator is sufficient.
2. Check whether the display and LEDs are indicating a normal operating state.

7.3LED Display
The inverters are equipped with two LEDs including “green”and “red”which provide
information about various operating states in the following ways. They are marked
with “Power”and “Fault”, respectively. When the inverter is power on from the
generator and operating correctly, the green LED is on. The red light is flashing during
the inverter is operating correctly indicates a fault in the system or inverter, and the
LCD display provides the exact information.
LED DC Power in (green):
The green LED is illuminated from a generator voltage of approx. 120V onward and
extinguishes as soon as the generator voltage falls below 100V. The DC Power in LED
signals that the inverter is in its active state and the inverter controls are enabled. If
this LED is not lit up which means the inverter will not be able to start grid feeding.
Under normal operating conditions the LED is illuminated in the morning when there
is enough daylight, and extinguishes again when it gets dark.
Under normal operating conditions the inverter starts grid feeding in the morning
and terminates this process as it becomes dark. This process might be repeated
several times throughout the day, especially in the morning and evening. This is not a
