Safety Hint: Please don’t connect PV array posi�ve or nega�ve pole to the ground, it could cause serious damages to the inverter.
  • 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 The AC output connector is divided into three parts: matching socket, sleeve and sealing- sleeve, as shown in picture 5.7, the steps are as follows: Step 1: Remove the cable sealing ring and sleeve in sequence from the AC connector. Step 2: Use strippers to strip the protec�ve sheath and insula�on layer of the AC cable to the right length, as shown in Picture 5.8.

  • Page 18 5.3 The connec�on of the ground line Good grounding is good for resis�ng surge voltage shock and improving EMI perfor- mance.Therefore, before connec�ng AC, DC and communica�on cables, you need to ground the cable firstly. 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 equipoten�al connec�on.

  • Page 22 7 Zero export func�on via SUN limiter The inverter has external zero export func�on. This func�on is op�onal. It can collect counter- current power to control the output power of the inverter, so that the power of inverter and load can be offset, and the excess power will not be fed back to the grid. If you purchase the inverter with zero export func�on, an external zero export device ( SUN limiter or energy meter) will be included in the package which is necessary for the func�on.The SUN limiter shows as Pic 7.1.You can see corresponding line mark next to the green interface.
