Installation
04
To selects location for the inverter, the following criteria should be considered:
• Do not install in small closed spaces where air can not circulate freely. To avoid
overheating, always make sure the flow of air around the inverter is not blocked.
• Exposure to direct sunlight will increase the operational temperature of the inverter and
may cause output power limiting. Kstar recommends inverter installed to avoid direct
sunlight or raining.
• To avoid overheating ambient air temperature must be considered when choosing the
inverter installation location. Kstar recommends using a sun shade minimizing direct
sunlight when the ambient air temperature around the unit exceeds 104°F/40°C.

• Install on a wall or strong structure capable of bearing the weight.
• When 1 or more inverters are installed in one location, a minimum 300mm clearance should
be kept between each inverter or other object (if a canopy is added, a distance of 500mm
must also be kept). The bottom of the inverter should be 500mm clearance to the ground.
▲ Figure 4.2 Inverter Mounting clearance
• Visibility of the LED status indicator lights and the LCD located at the front panel of the inverter
should be considered.

NOTE:
Nothing should be stored on or placed against the inverter.
It is not allowed to lay the machine horizontally for a long time, which will affect
the heat dissipation.
The inverter shall be mounted vertically. The steps to mount the inverter are listed
below:
1. According to Figure 4.2, select the bracket mounting height and mark the mounting
hole. After marking, punch the hole according to the mark. For brick wall drilling,
expansion bolts shall be suitable for fixing.
Bracket
Self tapping screw
Expansion pipe
• Install vertically with a maximum incline of +/-5° . If the mounted inverter is tilted to an angle
greater than the maximum noted, heat dissipation can be inhibited, and may result in less
than expected output power.

3. Use the suitable screws to fix the bracket to the wall.
WARNING:
The inverter must be mounted vertically.
4.Lift up the inverter (be careful to avoid body strain), and align the back bracket on the inverter
with the convex section of the mounting bracket. Hang the inverter on the mounting bracket
and make sure the inverter is secure (see Figure 4.5).
▲ Figure 4.5 Wall Mount Bracket
5. Use M screws in accessory to lock the inverter to the mount bracket. 4
4.3 Electrical Connections
4.3.1 Connect PV side of inverter
The electrical connection of the inverter must follow the steps listed below:
1. Switch the Grid Supply Main Switch (AC) OFF.
2. Switch the DC Isolator OFF.
3. Assemble PV input connector to the Inverter.
Check whether the polarity of the connecting cable of the photovoltaic string is
correct, and ensure that the open circuit voltage under any condition does not
exceed the upper limit of the inverter input value of 1100V.
Before connection, please make sure the polarity of the output voltage of PV
array matches the "PV+" and "PV-" symbols.
Please don't connect PV array positive or negative pole to the ground, it could
cause serious damages to the inverter.

5.1 Start the Inverter
To start up the Inverter, it is important that the following steps are strictly followed:
1. Switch the grid supply main Switch (AC) ON first.
2. Switch the DC switch ON. If the voltage of PV arrays are higher than start up voltage,
the inverter will turn on. The LED status indicator will light.
3. When both the DC and the AC sides supply to the inverter, it will be ready to generate
power. Initially, the inverter will check both its internal parameters and the parameters
of the AC grid, to ensure that they are within the acceptable limits. At the same time,
the green LED will flash and the LCD displays the information of INITIALIZING.
4. After 60-300 seconds (depending on local requirement), the inverter will start to generate power.
The green LED will be on continually and the LCD displays GENERATING.
WARNING:
Do not touch the surface when the inverter is operating. It may be hotand
cause burns.
5.2 Stop the Inverter
To stop the Inverter, the following steps must be strictly followed:
1. Switch the Supply Main Switch (AC) OFF.
2. Wait 30 seconds. Switch the DC Switch OFF. All the LEDs of the inverter will be off in
one minute.
