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" state. Whilst "waiting" the inverter uses just enough
power from the PV panel to monitor the internal system status. In normal mode the LED is green.
3.2
Fault mode
The internal intelligent controller can continuously monitor and adjust the system status. If the inverter detects
any unexpected conditions such as grid problems or internal failure, it will display the information on its LCD
and the LED will be red.
3.3
Shutdown mode
During periods of little or no sunlight, the inverter automatically stops running. In this mode, the inverter does
not take any power from the grid. The display and LEDs on the front panel do not work.
Note !
Operating the inverter is quite easy. During normal operation, the inverter runs automatically. However, to achieve maximum
inverter conversion efficiency, please read the following information:
3.4
Automatic ON-OFF
The inverter starts up automatically when DC power from the PV panel is sufficient.
Once the PV inverter starts it enters one of the following 3 states:
1.
Standby: The PV string can only provide just enough voltage to meet the minimum requirements of the
controller.
2.
Waiting: When the PV string DC voltage is greater than 100V, the inverter enters a enters a "waiting"
state and attempts to connect to the grid.
3.
Normal operation (first start up): When PV string DC voltage is greater than 150V, the inverter operates
in the normal state.

Starting-up display sequence
Once the PV power is sufficient, the inverter displays the following information:
