● Before turning on the AC switch between the inverter and the power grid,
check that the AC voltage is within the specied range using a multimeter.
● If the solar inverter has not been running for more than half a year after being
mounted, it must be checked and tested by professionals before being put into
operation.
Procedure
Step 1 Turn on the AC switch between the inverter and the grid.
If you perform Step 2 before Step 1, the inverter reports a fault about abnormal
shutdown. The inverter can start normally after the fault is automatically cleared.
Step 2 Set DC SWITCH 1 (MAIN SWITCH) at the bottom of the SUN2000 chassis to ON.
Step 3 Check the status of LED 1. If it is steady green, set DC SWITCH 2 and DC SWITCH
3 to ON.
