Steps
- Configure PV module information.
| Parameter name | Description |
|---|---|
| Favorites | Display the PV modules favorited by users. |
| Manufacturer | Click  Icon to select PV module manufacturer. |
| Model | Click Icon to select the PV module model. After the model is selected, the detailed information of the photovoltaic module is automatically filled in, and modification is supported. |
- (Optional) Collect PV module information.
You can modify the PV module parameter value, click 
Icon, click “Next” to save the current PV module information.
Click on ‘’
Icon’’, click “Next” to cancel the current favorite PV module information.
- Configure the PV sub-array information.
Click on ‘CLICK TO ADD PV ARRAY’, add “photovoltaic sub-array”.
| parameter name | Description |
|---|---|
| Name | Name of the photovoltaic sub-array. The default is PV sub-array 1, which supports modification within 32 characters. |
| Module Model | Configure the PV module model selected in the PV information, which cannot be modified. |
| Number of PV modules | The default is 100, and the range is 1~1000000. |
| STC peak | |
| [kWp] | Maximum power under STC conditions. After entering the number of photovoltaic modules, the system automatically calculates the peak power and cannot be modified. |
| Installation Type | Click  Icon to select the installation type. Roof: The maximum ambient temperature plus 30 °C participates in the calculation of Min.V DC. Grounding support: the highest ambient temperature plus 20 °C to participate in the calculation of Min.V DC. |
| Azimuth [°] | Azimuth of the photovoltaic sub-array. The default is 0°, and the range is -180° ~ + 180°. 0° is south, +90° is west, -90° is east. |
| Inclination [°] | Inclination angle between the photovoltaic sub-array and the ground. The default is 30°, and the range is 0° ~ 90°. 0° is horizontal, 90° is vertical. |
(Optional) Repeat step 3 to add multiple photovoltaic sub-arrays.
The installation type of two or more photovoltaic sub-arrays must be the same.Click the upper right corner of the photovoltaic sub-array
Icon to delete the PV sub-array information.
Only when there are two or more photovoltaic sub-arrays can the photovoltaic sub-array be deleted.Click “Next” to configure the PV module and PV sub-array information successfully.
