Seaward Electronic, a UK manufacturer of electrical safety test equipment, has expanded its photovoltaic testing range with the introduction of the PV:1525-IV, adding IV curve tracing capability to its PV:1525 Series.
The series is designed for commissioning and testing rooftop solar installations, supporting systems up to 1500V. It combines electrical commissioning tests with performance analysis within a single platform.
The PV:1525 Series supports open-circuit voltage measurements up to 1500V DC, short-circuit current up to 25A, insulation resistance testing, and continuity checks. This aligns with the requirements of higher-voltage residential and commercial solar systems.
The addition of IV curve tracing allows installers and operations and maintenance teams to assess module and string performance during commissioning, alongside standard safety testing.
Integrated testing improving commissioning workflow
The platform is designed to follow a consistent testing process, helping to reduce errors and support repeatable commissioning across installations.
Nathan Barwell, Head of Product Management at Seaward, notes, “Installers need tools that work the way they do on site.
“With the PV:1525 Series, our focus has been on simplifying PV commissioning, reducing the number of tools required, and giving installers confidence that their testing is complete, compliant, and ready for handover.
“With IV curve tracing integrated, the PV:1525-IV allows installers to assess module and string performance directly during commissioning. This makes it possible to identify deviations from expected performance at an early stage, without the need for additional test equipment.”
The tester also includes a Dynamic Surge Suppression System to manage inrush current during short-circuit testing, reducing stress on equipment when working with high-capacity arrays.
Additional features include Bluetooth connectivity for recording test results and over-the-air updates to maintain software functionality.
The PV:1525 Series, including the PV:1525-IV, is available now.
