The Seaward PV:1525-IV combines the PV electrical safety and commissioning capabilities of the PV:1525 with advanced IV curve analysis. It enables on-screen curve visualisation to assess PV system performance, compare expected and actual output, identify faults and support more detailed diagnostics.
The PV:1525-IV builds on core system testing, adding advanced IV curve analysis to validate system performance and identify faults that standard testing may miss.
Designed for deeper insight, it enables installers and engineers to compare expected and actual output, supporting more accurate diagnostics, faster fault finding, and greater confidence in system quality.
With on-screen curve visualisation, users can quickly assess system behaviour and verify results with confidence. This helps highlight performance issues early and supports more informed decisions on site.
