Installation

4.1 Select a Location for the Inverter
To select a location for the inverter, the following criteria should be considered:

• Exposure to direct sunlight may cause output power derating. It is recommended to avoid installing the inverter in direct sunlight.
• It is recommended that the inverter is installed in a cooler ambient which doesn’t exceed 40℃.

WARNING: Risk of fire
Despite careful construction, electrical devices can cause fires.

• Do not install the inverter in areas containing highly flammable materials or gases.

• Do not install the inverter in potentially explosive atmospheres.

• The mounting structure where the inverter is installed must be fireproof.

• Install on a wall or strong structure capable of bearing the weight of the machine (24kg).

• Install vertically with a maximum incline of +/- 5 degrees, exceeding this may cause output power derating.

• To avoid overheating, always make sure the flow of air around the inverter is not blocked. A minimum clearance of 500mm should be kept between inverters or objects and 1000mm clearance between the bottom of the machine and the ground.
  

• Adequate ventilation must be provided.

NOTE:
Nothing should be stored on or placed against the inverter.

4.2 Mounting the Inverter
Dimensions of mounting bracket:

Once a suitable location has be found accordingly to 4.1 using figure 4.3 mount the wall bracket to the wall.
The inverter shall be mounted vertically.
The steps to mount the inverter are listed below:

1. Select the mounting height of the bracket and mark the mounting holes.
   For brick walls, the position of the holes should be suitable for the expansion bolts.

2. 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 4.4)

WARNING:
The inverter must be mounted vertically.

4.3 PE Cable Installation
An external ground connection is provided at the right side of inverter.
Prepare OT terminals: M4. Use proper tooling to crimp the lug to the terminal.
Connect the OT terminal with ground cable to the right side of inverter. The torque is 2N.m.

4.4 PV Input Cable Installation

Before connecting inverter, please make sure the PV array open circuit voltage is within the limit of the inverter.
Before connection, please make sure the polarity of the output voltage of PV array matches the“DC+”and“DC-”symbols.
Please use approved DC cable for PV system.

1.  Select a suitable DC cable and strip the wires out by 7±0.5mm. Please refer to the table below for specific specifications.
   

2. Take the DC terminal out of the accessory bag, turn the screw cap to disassemble it, and take out the waterproof rubber ring.
   

3.  Pass the stripped DC cable through the nut and waterproof rubber ring.
   

4. Connect the wire part of the DC cable to the metal DC terminal and crimp it with a special DC terminal crimping tool.
   

5. Insert the crimped DC cable into the DC terminal firmly, then insert the waterproof rubber ring into the DC terminal and tighten the nut.
   

6. Measure PV voltage of DC input with multimeter, verify DC input cable polarity.
   

7. Connect the wired DC terminal to the inverter as shown in the figure, and a slight “click” is heard to prove the connection is correct.
   

CAUTION:
If DC inputs are accidently reversely connected or inverter is faulty or not working properly, it is NOT allowed to turn off the DC switch. Otherwise it may cause DC arc and damage the inverter or even lead to a fire disaster.
The correct actions are:
Use a clip-on ammeter to measure the DC string current.
If it is above 0.5A, please wait for the solar irradiance reduces until the current decreases to below 0.5A.
*Only after the current is below 0.5A, you are allowed to turn off the DC switches and disconnect the PV strings.

• In order to completely eliminate the possibility of failure, please disconnect the PV strings after turning off the DC switch to aviod secondary failures due to continuous PV energy on the next day.
  Please note that any damages due to wrong operations are not covered in the device warranty.
