, regaining entry into the system is critical. A missing or forgotten local administrator password blocks your ability to update grid profiles, manage battery storage settings, or reconfigure home Wi-Fi networks. Thankfully, Huawei provides a physical power-cycling override to restore default login configurations locally.

Resetting the installer password on a inverter is a critical procedure used when local commissioning access is lost. This process involves a specific hardware-triggered power sequence to restore factory settings for local login, WLAN name, and WLAN password. Core Reset Procedure
Luca called the site manager and confirmed authorization. The manager produced an email from the original installer confirming handover. With permission documented, Luca consulted the official technical manual and the online support portal. The manual described a secure, manufacturer-approved reset path: identify the correct model and firmware version, use the inverter’s local interface or the dedicated service tool, and, if needed, obtain a one-time reset code or guidance from Huawei support. It warned against attempting hardware tampering or undocumented backdoor methods—those could damage the unit or breach legal and safety rules.
When trying to connect to the inverter, turn off your mobile data/4G/5G, as your phone might try to use mobile data instead of the direct Wi-Fi connection to the inverter.
Turn off the DC switch (if your model has one) and the AC backup switch. Wait 5 minutes for capacitors to discharge. Attempting random passwords too many times will lock
Resetting is best done in the morning or at night when solar irradiance is low to ensure the DC side doesn't fluctuate during the cycle. Huawei Technical Support Key Features of the Reset Process Resetting Password - SUN2000-(2KTL-6KTL)-L1 User Manual
Before flipping any physical circuit breakers, ensure you have gathered the following essentials:
inverter, you must perform a strict power-cycling sequence using both the AC and DC switches within a 3 to 4-minute window, followed by re-commissioning the device locally via the FusionSolar app. This manual hardware override clears the forgotten local login credentials and returns the built-in WLAN hotspot back to its factory default settings without erasing your underlying grid configurations.
Confirm that both the (located in your main home electrical switchboard) and the DC switch (located at the bottom left under the inverter body) are turned ON . It does not delete your historical energy yield
To execute the physical power cycle required to override the password, you must satisfy several operational conditions: : The Go to product viewer dialog for this item.
