7. MODES OF OPERATION
There are 3 different modes of operation.
7.1 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<120VDC)
，
Inverter
enters a “waiting” state. Whilst “waiting” Inverter uses just enough power from the
PV panel monitor internal system status. In normal mode the LED is green.
7.2 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 the LED will be red.
7.3 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.

Operating inverter is quite easy. During normal operation, Inverter runs
automatically. However, to achieve maximum conversion efficiency of Inverter

Le fonctionnement d’un onduleur est assez facile. Lors d’une phase normale,
l’onduleur fonctionne automatiquement. Cependant, afin d’atteindre l’efficacité de
conversion maximale de l’onduleur, veuillez lire les instructions suivantes :
Automatic ON-OFF: 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 minimum
requirements of the controller.
