set value after the inverter is normally connected to the grid, or when the AC power grid fails, the
inverter will automatically exit the "operation" mode and stop Feed the grid.
(b) Manual shut-down: If service personnel need to maintain or repair the inverter, please take the
following steps:
(1) Click “Inverter Parameter” and enter the user passwords (Contact our after-sales service center
of our company to acquire the passwords) to enter the inverter parameter setting interface; the
inverter will be shut down after clicking “Command Parameter”->“Shutdown” button.
(2) Press the emergency stop button on the panel to shut down the inverter in case of emergency.
Manual start-up is required after manual shut-down. Click “Inverter Parameter” and enter the user
passwords (please contact our after-sales service center of our company to acquire the passwords)
to enter the inverter parameter setting interface; click “Command Parameter”->“Startup” button to
start the inverter. Then the inverter will start up and operate normally if the start-up condition is
met. Otherwise, the inverter stands by.
(c) Maintenance shut-down: If the service personnel need to repair the inverter, please shut down
the inverter by LCD operations and then discharge the energy in the equipment. Take the
following steps to discharge the inverter: Refer to 9.3.5 “Command Parameter”.
After executing the De-energy command, the DC capacitor bus begins to discharge. The LCD can
display the state as shown in Figure 8-2 after discharging is completed.
After discharging, measure the voltage of the DC capacitor bus with a universal meter to make
sure the safety voltage is reached, and then maintenance can be started.
Figure 8-2 Successful discharging
If the LCD shows that discharging energy fails as shown in Figure 8-3, turn off AC and DC circuit
breakers and discharge the energy manually before maintaining the inverter.
