Seaward Electronic has expanded its PV testing offering with the launch of the PV:1525-IV, introducing IV curve tracing capability and completing the PV:1525 Series – a range of PV installation testers for 1,500V systems, combining electrical commissioning tests and IV curve tracing within a single platform.

Built for residential and commercial rooftop solar systems, the PV:1525 Series combines essential electrical commissioning tests with a single, intuitive workflow. With the addition of IV curve tracing, installers and O&M professionals can now move from core safety testing through to advanced performance analysis using the same platform.

The Series supports open-circuit voltage (Voc) measurements up to 1,500V DC, short-circuit current (Isc) up to 25A, insulation resistance testing to 1,500V DC, and continuity measurements. This makes it well suited to today’s higher-voltage residential and commercial rooftop systems, where traditional 1,000V tools may no longer be sufficient.

The PV:1525-IV extends the series with IV curve tracing for performance analysis, enabling installers and O&M professionals to move beyond basic safety checks and gain deeper insight into system performance. With both models built on the same intuitive workflow, users can choose the level of capability that matches their application, from fast commissioning through to detailed performance analysis.
