Operation Modes
8.1. Waiting mode
When the PV voltage is higher than 100V, Inverter will be powered up, and enters
“waiting” mode.
In this mode, inverter will check the system parameters. If the system is normal, and
PV voltage is higher than 150Vdc, the inverter will attempt to connect to grid.
8.2. Normal mode
In this mode, the inverter works normally and LED turns green.
Information
The inverter starts up automatically when the DC power from the
PV panel is sufficient.
8.3. Fault mode
8.3. 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.
Information
Detailed fault information refers to chapter 10 Troubleshooting.
8.4. Shutdown mode
8.4. Shutdown 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.
Information
If the PV string DC voltage is too low (
70 Vdc) or DC switch
open, the inverter will also turn to shutdown Mode
≤
Whenever the DC voltage is higher than 150Vdc, inverter converts power to grid
as generated by the PV panels;
Whenever the DC voltage is lower than 100Vdc, the inverter will work in standby
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;
