    3. oveRvieW 3.1 intRoducing thE gRid-connEctEd PV systEm The grid-connected PV System is mainly composed of 4 parts: the PV-panels, the PV-Inverter, the AC-Connection Unit (the connection Interface) and a connection to the Public Grid. When a PV-panel is exposed to sunlight and connected to an inverter, it generates DC power.

  • Page 18 (3) Unscrew the cable lock and prepare your AC cable. AC cable lock (4) Remove the rubber plug from inside the AC connector socket. Rubber Plug (no hole in it) (5) Insert the provided rubber bushing with three holes into the AC connector socket.
  • Page 19 (6) Now insert the three wires of the AC cable into the bushing holes. (7) Fix the brown wire to L (Line); the blue wire to N (Neutral); and the yellow-green wire to G (Ground). All three wires should be firmly connec- ted.

    (9) Now screw the Connector Locker in tight to fix the bushing and cable. 5.4 connEcting thE PV-PanEl (1) First make sure that the maximum open circuit voltage Voc of each PV string is below 750VDC UNDER ANY CONDITION. (2) Always connect PV-Panel positive (+) terminal to PV-Inverter DC positive (+) terminal, and the PV-Panel negative (-) terminal to PV- Inverter DC negative (-) terminal.
  • Page 21: Connecting To The Connection Unit

    (4) To fully optimize the PV DC output set-up, use the following confi- guration guidelines: (a) For PV DC output less than 8.5 A, use a single pair of PV-Inverter DC terminals. (b) For PV DC output between 8.5 A and 17 A, use two sets of inver- ter DC terminals.
  • Page 22: Installation Checklist

    5.6 installation chEcklist (1) High voltages exist when the PV-Panel is exposed to the sun. Expo- sed terminals of the PV-Panel are alive, and can cause electric shock. Avoid making physical contact with live parts of the device. (2) After the PV-Panels are connected to the PV-Inverter, the output voltage is higher than 100 VDC and the AC grid is not connected to the inverter, the LCD displays “Model= XXXXXX”->...
  • Page 23 The PV-Inverter is feeding power to the grid, and the green LED dis- plays. Before connecting the PV-Panels to DC terminals, make sure the polarity of each connection is correct. An incorrect connection could damage the device permanently. (5) Congratulations, you have successfully installed your PV-Inverter!

    6.4 maximum PowER Point tRacking (mPPt) Due to its advanced design, your PV-Inverter can track the maximum power from any PV-Panel under any condition. If the output power display is stable, your PV-Inverter is converting the maximum power available. If the power reading fl uctuates, the device is tracking power changes due to varying levels of sunlight.
