Resetting Password
6.2
1. Check that the AC and DC sides of the inverter are both powered on, and indicators
and are steady green or blinking slowly for more than 3 minutes.
2. Turn off the AC switch, set the DC SWITCH of the inverter to OFF, and wait until all indicators
on the inverter panel turn off.
3. Complete the following operations within 4 minutes:
a. Turn on the AC switch and wait for about 90s or until the inverter indicator blinks.
b. Turn off the AC switch and wait about 30s or until all LED indicators on the inverter
panel turn off.
c. Turn on the AC switch and wait for about 30s or until all LED indicators on the inverter
panel blink and then turn off after about 30s.
a. Wait until the indicator blinks.
b. Connect to the app using the initial WLAN hotspot name (SSID) and initial password
(PSW), which can be obtained from the label on the side of the inverter.
c. On the login page, set a new password and log in to the app.
6. Set router and management system parameters to implement remote management.
You are advised to reset the password in the morning or at night when the solar irradiance is low.
4. Wait until the three green LEDs on the inverter panel blink fast and then the three red
LEDs blink fast, which indicates that the password is restored.
5. Reset the password within 10 minutes. (If no operation is performed within 10
minutes, all parameters of the inverter remain unchanged.)

Powering On the System
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 operating voltage range of the
inverter. If the voltage is not in the allowed range, check the circuits.
2. Turn on the AC switch.
3. Turn on the DC switch (if any) between the PV strings and the inverter.
4. (Optional) Remove the locking screw next to the DC SWITCH on the inverter.
5. Set the DC SWITCH to ON.
6. Observe the LED indicators to check the status of the inverter.
7. (Optional) Observe the Smart Dongle LED indicator to check the status of the Smart Dongle.
