6.2 System Power-On

Prerequisites
Before turning on the AC switch between the inverter and the power grid, use a
multimeter to check that the AC voltage is within the allowed range.
Before the equipment is put into operation for the first time, ensure that the
parameters are set correctly by professional personnel. Incorrect parameter
settings may result in noncompliance with local grid connection requirements and
affect the normal operations of the equipment.
If the DC power supply is connected but the AC power supply is disconnected, the
inverter will report a Grid Loss alarm. The inverter can start properly only after
the power grid recovers.
Procedure
Step 1 Turn on the AC switch between the inverter and the power grid.
Step 2 (Optional) Remove the locking screw from the DC switch.

Step 4 Turn on the DC switch at the bottom of the inverter.
Step 5 Observe the LEDs to check the inverter operating status.
