  • Page 25: Auto-Power

    6.2. Auto-power The PV-Inverter starts up automatically once DC-power from the PV-Panel is sufficient. There are 3 modes of operation. 6.3. Operating Modes 1. Normal In this mode, the PV-Inverter automatically detects the system status and selects the best mode of operation. If the power from the PV-Panel is greater than 150VDC, the supply is converted to AC fed in to the grid.
  • Page 26 4. Three Operating States: Standby, Waiting, Normal During normal operation, the PV-Inverter enters a ‘standby’ state at voltages below 100V. Between 100V and 150V the device enters the ‘waiting’ state and begins checking its own internal status. The ‘Normal’ state is entered when the voltage is above 150V. The following example shows the LCD when the PV-Panel input increases above 100V: The LCD first displays the model name...
