6.1 Powering On the Inverter
Precautions
NO TICE
● Before the equipment is put into operation for the rst time, ensure that the
parameters are set correctly by professional personnel. Incorrect parameter
settings may result in noncompliance with local grid connection requirements
and
aect 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 Failure alarm. The inverter can start properly
only after the power grid recovers.
Procedure
Step 1 At the AC switch between the inverter and the power grid, use a multimeter to
measure the grid voltage and ensure that the voltage is within the allowed
operating voltage range of the inverter. If the voltage is not in the allowed range,
check the circuits.
Step 2 Turn on the AC switch between the inverter and the power grid.
Step 3 Turn on the DC switch (if any) between the PV strings and the inverter.
Step 4 (Optional) Remove the knob locking screw next to the DC SWITCH on the inverter.
Step 5 Set the DC SWITCH on the inverter to ON.
Step 6 Observe the LED indicators to check the status of the inverter.
