Operation Modes

Operation Modes
12.1 Normal Mode
In this mode, the inverter works normally and LED turns green.
1. Whenever the DC voltage is higher than 150Vdc, inverter converts power to grid
as generated by the PV panels;
2. Whenever the DC voltage is lower than 150Vdc, the inverter will work in waiting
state and attempt to connect the grid. In waiting state the inverter consumes just
enough power generated by the PV panel to monitor the internal system status;
The inverter starts up automatically when the DC power from
the PV panel is sufficient.
NOTICE
12.2 Fault Mode
The internal intelligent controller can continuously monitor and adjust the system
status. If inverter finds any unexpected conditions such as system fault and inverter
fault, the fault information will be displayed on the LCD. In fault mode the LED turns
red.
Detailed fault information refers to 13. Trouble shooting.
NOTICE
12.3Shutdown Mode
Inverters automatically stop running during periods of little or no sunlight. In
shutdown mode the inverters take no power from the grid and panel, and the LCD
and LED turns off.
If the PV string DC voltage is too low, the inverter will also
turn to Shutdown Mode.

De-rating Operation

De-rating Operation
Temperature
The inverter will monitor the temperature of the heat-sink. Once the temperature
exceeds 75°C (167°F) ,the system will reduce the output power until the temperature
drops under the critical value. The inverter will shut down the power output to the
grid if the temperature reaches 85°C (185°F). If this occasion happens often, it is
necessary to check whether the inverter is mounted at an appropriate place with
good ventilation and not directly exposure to the sunshine.
