6.2 Powering On the System
Precautions
Before turning on the AC switch between the SUN2000 and the power grid, use a multimeter
set to the AC position to check that the AC voltage is within the specified range.
Procedure
Step 1 Turn on the AC switch between the SUN2000 and the power grid.
If the DC is on and the AC is off, the SUN2000 reports a Grid Failure alarm. The SUN2000
starts normally only after the fault is automatically rectified.
Step 2 If there is a DC switch between the PV string and the inverter, turn on the DC switch.
Step 3 Set the DC SWITCH at the bottom of the SUN2000 to the ON position.
Step 4 Wait for about 1 minute, and then observe the LED indicators of the inverter to check the
running status.
