Figure 25. Choose “Installer” login type • The view defaults to the LIVE INSTALLATIONS tab.
Setup 2: Enter installation site details. • The Installation Name is used to identify the installation site: this name will also be displayed on the installation owner’s monitoring dashboard, so use something customer-viewable. • Reference Numbers are optional: for example, they can help the installer to cross-reference the installation site to an account number. Step 3: Input the system information.
Step 5: Begin layout by adding a section. • Before any sections are created, the screen will appear as below. • Select the ADD A NEW SECTION button to create a new PV System layout. Section Details Q: Why would an installation consist of “sections”? A: Smaller installations are not as likely to need to be in sections.
Step 7: Adjust section layout. • Double-clicking on the section will allow the user to edit the individual panel details. If the installer wishes to bypass the automatic inverter serial numbers in the setup, the inverter serial numbers can be added manually, panel by panel. • Adjust, re-size, or reposition the section. • Double-click section to edit individual PV panels. Use the layout tools to assist with layout design. • Later, you will assign inverter serial numbers to the PV panels.
Installation Layout Tools Key Select All Align Vertically, Left or Right And Align Horizontally, Top or Bottom Distribute Horizontally and Distribute Vertically Match Rotation Match Scale Undo Optional: Manual Adjustments and Serial Numbers Rather than using the array layout tools and allowing the inverters to automatically report their serial numbers, the installer can manually adjust the panels and enter the inverter serial numbers one-by-one.
• The SERIALS tab allows the user to manually load the inverter serial numbers, or to edit numbers that are already there. • Type the inverter serial in the Search box. Click the ADD TO LIST button to add it to the Available Serials column. Drag the added number from the column onto the module. Optional: Saving a pending installation • After the layout is done, click the SAVE button. This will allow you to pause and return to the installation later, if necessary. 7.3.
• The installer will need to drag each inverter serial number to the appropriate module. Refer to the “PV module / micro inverter serial number form” that was with stickers during the installation for their positions in the array design. Step 3: Check work and launch installation • When you are with dragging the available serials to the modules, save and You will arrive on the PENDING INSTALLATIONS Screen. • Inspect the information categories for green check marks.
Step 4: Inform the customer of new user account. • Click the NEW USER button for the system to automatically send the installation owner a User name and Password to access the monitoring account.
