Inverter placement
The inverter should be placed in the shade. You should also make sure that it doesn’t overload the roof. Cable mapping and cable calculation requirements have to be considered as well.
The inverter can be placed inside the building, on the building or on the ground. You can assign an already drawn inverter or draw it after clicking the ‘Add’ button.
You should also add the required measurements and the height between the inverter and the ground.
Inverter placement
The inverter is hanging on the building. To place an inverter on the building, you should draw a rectangle next to the building, add the required measurements and indicate the inverter’s elevation from the ground. Then you should click on the ‘Pick form dwg’ button, pick the anticipated rectangle, and hit ‘Enter’.
The inverter is inside the building. To place the inverter inside the building, you need to draw a rectangle in the place where the inverter should be. After that, you need to add its required measurements and the elevation from the floor, and click the ‘Pick form dwg’ button. Then you should select the rectangle and hit ‘Enter’.
The inverter is on the ground. When you want to place the inverter on the ground, you need to draw a rectangle in the place where the inverter should be and add its required measurements. You should also set the elevation from the ground to zero. Then you should click the ‘Pick form dwg’ button, click on the rectangle, and hit ‘Enter’.
The inverter is on the roof. First, you should draw a rectangle on the roof of the building, and add the measurements of the inverter. Then after choosing the inverter placement on the roof from the dropdown menu, click the ‘Pick form dwg’ button, select the rectangle and hit ‘Enter’.
Another option of placing the roof inverter is to choose the ‘On the roof’ option from the placement dropdown menu, add the inverter measurements, and click the ‘Add’ button. Then you should draw it on the desired spot on the roof, and hit ‘Enter’.
Stringing
The tool offers 3 types of stringing: semi-automated (modules), automated (PV Area), or custom (manual).
Note: In the case of E-W layout, system strings only E with E and W with W.
Moreover, keep in mind that software strings modules together when they have the same inclination, orientation and azimuth
Automated stringing (PV Area). You can choose from the two types of stringing: Single Row or U-string. When you choose the ‘Single row’ option, the direction of the strings should be chosen from the following directions: up, down, left, or right. You should also provide the expected range of the modules per string. This is needed to have the longest possible string to fit in the range. After clicking the ‘String’ button, you should pick one or more PV areas that need to be strung. Finally, the software will inform you of the modules unstrung due to the number of modules in the PV area. A notification will pop up and the affected modules will be marked in red. Please see the visuals below:
When you choose the U-string type, you should choose between two directions of strings: horizontal or vertical. The tool will then provide you with the required range of the modules per string, so that the system would follow it when stringing the modules in the chosen PV area. Then, after clicking the ‘String’ button, you should pick one or more PV areas that you want to string. Finally, the software will inform if any of the modules were not strung due to the amount of them in the PV area. The notification and the affected modules will be marked in red.
Semi-automated stringing (modules). The semi-automated stringing has the same models and types as automated stringing. The only difference is that semi-automated stringing allows users to select the group of modules to be strung instead of the PV area. This provides a possibility of string management and better flexibility in tricky areas with many obstacles.
Destringing. In order to remove stringing, simply click the ‘Destring modules' button, then choose the PV areas that need to be de-strung, and hit ‘Enter’.
