User Manual
This chapter mainly introduces how to start and shut down the inverter.

5.1 Start Inverter

Step 1 Switch on the DC switch in the inverter and the DC switch in the project site. When the PV array
provides enough startup voltage, PV connection indicator will be on.
Step 2 Switch on the AC switch between inverter and grid, the fault indicator is off.
Step 3 If the DC and AC supply power normally, the inverter will prepare to start. At first, the inverter will
check the inner parameters and AC grid parameters, if they are in the normal range, a moment later,
the inverter will check the insulation impedance.
Step 4 A moment later, the inverter will generate power normally. The grid connection indictor will be on.
