Dubai Electricity and Water: Tests of PV Strings Mobile App
The Dubai Electricity and Water: Tests of PV Strings mobile app allows you to replace your paper inspection checklist with a tablet or smartphone.
How does it work?
The mobile form includes fields to document items such as string, voltage, start time, stop time and insulation resistance. Once the mobile app is filled out a secure PDF is generated. The PDF is easy to share, and a copy is stored in your account for your corrosion control records. You can also use the App Builder to personalize and customize this mobile form. Measure strings connected in parallel (e.g. to same combiner box) so that possible changes of solar radiation are minimized. Test each single short-circuited string, other strings in open. Before each new test open the DC disconnect, disconnect the last tested string and connect the following string to be tested. Finally, close the DC disconnect, and test. Measure short-circuited strings, downstream e.g. the DC disconnect of combiner box, inverter switched off.
