2. Safety warnings and instruc�ons Improper use may result in poten�al electric shock hazards or burns. This manual contains important instruc�ons that should be followed during installa�on and maintenance. Please read these instruc�ons carefully before use and keep them for future reference. 2.1 Safety signs Safety symbols used in this manual, which highlight poten�al safety risks and important safety informa�on, are listed as follows:...
Page 6
Shock Hazard: When PV module is exposed to sunlight, the output will generate DC voltage. Prohibit touching to avoid shock hazard. Shock Hazard: While disconnect the input and output of the inverter for maintenance, please waits for at least 5 mins un�l the inverter discharge the remnant electricity. High Temperature Hazard: Local temperature of inverter may exceed 80℃...

4. Product installa�on 4.1 Select installa�on loca�on To select a loca�on for the inverter, the following criteria should be considered: WARNING: Risk of fire ● Do not install the inverter in areas containing highly flammable materials or gases. ● Do not install the inverter in poten�ally explosive atmospheres. ●...
Page 10
● Install on a wall or strong structure capable of bearing the weight. ● Install ver�cally with a maximum incline of +/-15°. If the mounted inverter is �lted to an angle greater than the maximum noted, heat dissipa�on can be inhibited, and may result in less than expected output power.

4.3 Inverter Installa�on The inverter should be mounted in a ver�cal posi�on. The steps of moun�ng are as follows 1. For brick walls, the posi�on of the holes should be suitable for the expansion bolts. 2. Make sure the bracket is horizontal and the moun�ng holes are in the correct points. Drilling the holes on the wall according the marks.

5 Electrical Connec�on 5.1 DC input terminal connec�on 1. Switch the Grid Supply Main Switch(AC)OFF. 2. Switch the DC lsolator OFF. 3. Assemble PV input connector to the inverter. Safety Hint: When using PV modules, please ensure the PV+ & PV- of solar panel is not connected to the system ground bar.
Page 14
The steps to assemble the DC connectors are listed as follows: a) Strip off the DC wire about 7mm, disassemble the connector cap nut (see picture 5.3). Pic 5.3 Disassemble the connector cap nut b) Crimping metal terminals with crimping pliers as shown in picture 5.4. Pic 5.4 Crimp the contact pin to the wire c) Insert the contact pin to the top part of the connector and screw up the cap nut to the top part of the connector.
Page 15
d) Finally insert the DC connector into the posi�ve and nega�ve input of the inverter, shown as picture 5.6 Pic 5.6 DC input connec�on Warning: Sunlight shines on the panel will generate voltage, high voltage in series may cause danger to life. Therefore, before connec�ng the DC input line, the solar panel needs to be blocked by the opaque material and the DC switch should be 'OFF', otherwise, the high voltage of the inverter may lead to life- threatening condi�ons.
Page 16
AC wire produc�on method is the same as that of 5.2.1. AC wire installa�on method: 1) Remove the 8 fixing screws on the AC junc�on box of the inverter as shown in Pic 5.7. A�er removing the junc�on box, you can see the terminals of the inverter. The default is 5 digits as shown in Pic 5.8.

5.3 Connec�on of the ground line Good grounded is important for resist the surge voltage shock and improve EMI's performance. So before the connec�on of AC, DC, communica�on connec�ons, inverter needs to ground first. For a single system, just ground the PE cable; For mul�ple machine systems, all PE cables of the inverter need to be connected to the same grounding copper platoon to ensure the equipotent connec�on.

Phone GPRS Router Web Server WIFI Pic 5.13 Internet monitoring solu�on 5.4.1 Installa�on of datalogger When the inverter is out of the factory, the loca�on of the installa�on of datalogger is sealed by a sealed plate as shown in Picture 5.14. When installing the datalogger, remove the sealing plate, replace it with the sealing plate with square hole in the accessories, and �ghten the screws.
5.4.2 Configura�on of datalogger For the configura�on of datalogger, please refer to illustra�ons of the datalogger. 6. Start up and Shut off Ensure that the inverter meets the following condi�ons before star�ng the inverter, otherwise it may cause fire or damage to the inverter without quality assurance, at the same �me the situa�on on our company does not undertake any responsibility.

9. Repair and Maintenance String type inverter doesn’t need regular maintenance. However, debris or dust will affect heat sink’s thermal performance. It is be�er to clean it with a so� brush. If the surface is too dirty and affect the reading of LCD and LED lamp, you can use wet cloth to clean it up. Warning: When the device is running, the local temperature is too high and the touch can cause burns.
Check the solar panel output connec�on. Failure in reading memory (EEPROM). Restart the inverter if the Read the memory error fault s�ll exists, contact your installer or Deye service. Failure in wri�ng memory (EEPROM). Restart the inverter if the Write the memory error fault s�ll exists, contact your installer or Deye service.
