9.2. Powering on the System
Power on:
To turn on the inverter, the following steps must be performed in the order listed.
Step 1: close DC and AC circuit breakers;
Step 2: if the PV panel can provide enough power, the power module will work and light up
the LCD panel;
Step 3: the inverter will enter the self-check mode, and the LCD will display the remaining
reconnection time;
Step 4 : when the inverter enters the normal mode, the power will be fed into the grid, and the
LCD will display the power generation.
As long as the inverter operates normally, it will automatically track the maximum output
power of photovoltaic cells. At night, the light intensity is not enough to provide energy, the
inverter will automatically shut down. The next day, when the input voltage reaches the
starting value, it will start automatically.
Be careful!
The surface temperature of the inverter can reach up to 75
℃
To avoid the risk of burns, do not touch the surface when the
inverter is in operation mode.
In addition, the inverter must be installed out of the reach of
children.
Shutdown:
To stop the inverter, the following steps must be performed in the order listed.
Step 1:Disconnect the AC switch.
Step 2 : Wait for about 30 seconds (during which the capacitor on the AC side is discharged).
If the DC voltage of the inverter is higher than the starting threshold, the red power light will
be on. Disconnect the DC switch.
Step 3:Confirm that all indicators are off (about 1 minute).
Be careful!
Although the inverter DC disconnect switch is in the off position
and all indicators are off, the operator must wait 5 minutes to
open the inverter housing after disconnecting the DC power
supply.
