5 Operations on the Screen for Connecting
to the Commercial Solar Inverter

The app screenshots provided in this chapter correspond to the SUN2000 app 3.2.00.005 version. The data on the screenshots is for reference only.
The document describes the operation method on the Android UI. The actual UI prevails.
The parameters displayed on the screen vary according to the solar inverter model connected to the app.
The 1000 V and 1500 V solar inverters have the maximum input voltages of 1000 V and 1500 V respectively. The 1100 V solar inverter refers to the one with the maximum input voltage of 1100 V or SUN2000-33KTL-US/36KTL-US/40KTL-US. The maximum input voltage can be queried from the product nameplate or the user manual.
Delivering a reset, factory reset, shutdown, or upgrade command to the solar inverters may cause power grid connection failure, which affects the energy yield.
Only professionals are allowed to set the grid parameters, protection parameters, feature parameters, power adjustment parameters, and grid-tied point control parameters of the solar inverters. If the grid parameters, protection parameters, and feature parameters are incorrectly set, the solar inverters may not connect to the power grid. If the power adjustment parameters and grid-tied point control parameters are incorrectly set, the solar inverters may not connect to the power grid as required. In these cases, the energy yield will be affected.
