For the Huawei UPS5000-H, inverter startup is executed through the UPS's own control interfaces, which provide the ''Running Control / Inv. ON'' operation with the required confirmations and permissions. The UPS LCD (MDU touchscreen) supports inverter startup through menu operations such as selecting inverter start functions and confirming the action after authentication. The UPS WebUI also provides the same operational control path, where an operator logs in and issues the Inv. ON command under the UPS monitoring/running control pages. These two interfaces are part of the UPS monitoring and control design and are explicitly used for commissioning and routine O&M actions.

By contrast, ECC (data center controller) and NetEco (management platform) are mainly used for site-level monitoring, alarm collection, visualization, reporting, and centralized management. While they can display UPS status and alarms (and may integrate with UPS data), inverter startup is defined as a UPS running control operation performed on the UPS's LCD or WebUI control plane to ensure proper authorization, safety checks, and command traceability.
