Auto-Power; Operating Modes - Chint Power CPS SC4.6KTL-O Installation And Operation Manual

6.2. Auto-power

The PV-Inverter starts up automatically once DC-power from the
PV-Panel is sufficient. There are 3 modes of operation.

6.3. Operating Modes

1. Normal
In this mode, the PV-Inverter automatically detects the system status
and selects the best mode of operation.
If the power from the PV-Panel is greater than 150VDC, the supply is
converted to AC fed in to the grid. If the power is less than 100VDC, the
PV-Inverter displays "Waiting". During the wait state, the device uses
minimal power from the PV-Panel to monitor the system status.
During normal mode, the green LED is on.
2. Fault
The PV-Inverter's intelligent controller continuously monitors the
system status. Unexpected conditions such as grid problems or internal
failures are displayed on the LCD and the "Fault LED" turns on.
Faults are indicated by the red "FAULT" LED.
3. Shutdown
At the moment of reduced sunlight, the PV-Inverter automatically shuts
down. No power is used from the grid, the LCD display and LEDs on
the front panel do not work, and the function button is inactive.
