Seaward PV1525-IV
Introducing the Seaward PV1525-IV – Smart, Reliable Solar Testing for Today’s Professionals
The Seaward PV1525-IV sets a new standard in photovoltaic (PV) system testing. Built for installers, electricians, and O&M engineers, this advanced testing instrument delivers precision, efficiency, and intuitive functionality — all in a rugged, portable design.
Installers need tools that match the realities of site work. With the PV:1525 Series, the focus has been on simplifying PV commissioning, reducing the number of tools required, and giving installers confidence that testing is complete, compliant and ready for handover.
Modern PV commissioning places increasing demands on installers, from tighter schedules to heightened safety considerations when working on live systems. The PV:1525 Series has been developed to support a clear, logical testing workflow, helping to reduce the risk of errors while keeping processes simple and repeatable across installations.
A key advantage is the integrated Dynamic Surge Suppression System, which actively manages inrush current during short-circuit testing. High inrush current can place stress on both equipment and installations, but the PV:1525 Series monitors and suppresses it effectively. This allows installers to test with confidence, even on high-capacity PV arrays, without risking damage to the instrument. Integrated Bluetooth connectivity enables real-time documentation of test results on site, while over-the-air updates keep the instrument current without downtime, protecting long-term investment.
With its innovative user interface, the PV1525-IV retains the familiar ease of use from previous models while introducing powerful new features designed for the evolving needs of modern solar professionals. From residential rooftops to large-scale commercial arrays, the PV1525-IV is engineered to handle high-performance systems up to 1500V DC and 25A.
Users can tag test results with installation-specific details on the spot, making data organization and compliance reporting faster and easier. Built-in Bluetooth connectivity allows for quick syncing to a mobile app, enabling real-time viewing, sharing, and seamless software integration. This ensures your device stays updated with the latest features and firmware improvements.
