Seward Diagnostics

A Seaward test allows the OM team to quickly assess issues like ground continuity, open circuit voltage, string polarity and DC short circuit current – as well as PV string wire insulation integrity. A Seaward tester is the Commissioning Agent’s tool of choice. It ensures critical equipment and personnel safety at plant startup. As your system ages this test is critical to perform at least once yearly as most Data Acquisition Systems will not alert you to low performing or non-performing strings.
