    2.3 Connecting to the grid (AC utility) Measure the grid voltage and frequency. It should be 230VAC (or 220VAC) , 50/60Hz and single phase. Open the breaker or fuse between the PV inverter and the grid. For the inverter, connect AC wires as follows: Terminal Pressing screw cap Shell Ground...
  • Page 10: Checking

    2.5 Checking When the PV panels are connected and their output voltage is greater than 100 VDC but the AC grid is not yet connected, the message on the LCD display produce the following messages in order: ”Ser NO:xxx”->”xxxxxx”->”FW version”->”No AC connection’ and the LED will be red. Close the AC breaker or fuse between PV-Inverter and grid.
  • Page 11: Modes Of Operation

    Modes of operation There are 3 different modes of operation. 3.1 Normal mode In this mode, the inverter works normally. Whenever the supplied power from PV panel is sufficient (voltage>120VDC), the inverter converts power generated by the PV panel to the grid. If the power is insuf- ficient (voltage<100VDC), the inverter enters a “waiting”...

    Inverter Status Inverter is designed to be user-friendly; therefore, the status of the Inverter can be easily understood by reading the information shown on the front panel display. Ali possible messages are shown in the following table. DISPLAY OPERATION System fault Auto Test Failed Auto Test do not pass No AC Connection...
  • Page 15: Communications

    Communications 5.1 Communications software instructions RADIUS LigthNET is a PC software which communicates with the APV inverter to analyse its operating state. It is a convenient way of determining the inverter’s real-time operating state and operation log. Specification: Communicate with inverter by RS232 and Bluetooth. Construct net with inverter and RADIUS LigthNET via RS232, Bluetooth and the Internet.
  • Page 16: Trouble Shooting

    Trouble shooting Note ! In most situations, the Inverter requires very little service. However, if Inverter is not able to work perfectly, please refer to the following instructions before calling your local dealer. Should any problems arise, the LED on the front panel will be red and the LCD displays the relevant information. Please refer to the following for a list of potential problems and their solutions. SYSTEM FAULT Ground Fault 1. The ground current is too high. 2. Unplug the inputs from the PV generator and check the peripheral AC system. 3. After the cause of the fault is cleared, reconnect the PV panel and check the PV inverter status.
