5. Operating Your PV-Inverter
Modes of operation
There are 3 different modes of operation.
1. Normal mode: In this mode, Inverter works normally. Whenever the
supplied power from PV panel is sufficient (voltage>150VDC), Inverter
converts power to the grid as generated by the PV panel. If the power is
insufficient, (voltage<100VDC) Inverter enters a “waiting” state. Whilst
“waiting” Inverter uses just enough power from the PV panel monitor
internal system status. In normal mode the green LED is on.
2. Fault mode: The internal intelligent controller can continuously monitor
and adjust the system status. If Inverter finds any unexpected
conditions such as grid problems or internal failure, it will display the
information on its LCD and light up the red “Fault” LED.
3. Shutdown mode: During periods of little or no sunlight, Inverter
automatically stops running. In this mode, Inverter does not take any
power from the grid. The display and LED’s on the front panel do not
work.
