Seaward PV:1525-IV 1500V Solar PV Test Kit
The Seaward PV:1525-IV 1500V Solar PV Installation Tester and I-V Curve Tracer is a next-generation, compact, and field-ready solution designed for advanced diagnosis, performance analysis, and full lifecycle PV (photovoltaic) system testing. Built for installers and O&M engineers working on residential, commercial, and larger critical systems, it supports electrical safety testing and detailed performance measurements on PV installations up to 1500V DC and 25A.
Engineered to streamline commissioning, inspection, troubleshooting, and maintenance, the PV:1525-IV combines intuitive operation with powerful diagnostic capability. It verifies both electrical safety and system performance in line with international standards such as IEC 62446 and EN 61557, while delivering deeper insight into panel and string behaviour. With its built-in I-V curve tracing functionality, it goes beyond standard testing, making it the ideal choice for identifying faults, diagnosing underperformance, and validating maximum power output.
Comprehensive Electrical Safety Tests
The PV:1525-IV performs ground continuity, insulation resistance, open-circuit voltage, and short-circuit current measurements with high accuracy. Open-circuit voltage testing ranges from 5.0V DC to 1500V DC with 0.1V resolution, while short-circuit current measurement spans 0.50A DC to 25.00A DC with 0.01A resolution, supporting systems up to 37.5kW. Insulation resistance testing offers selectable voltages of 250V, 500V, 1000V, and 1500V DC, with a measurement range of 0.05MΩ to 300MΩ, allowing fast detection of insulation faults. Continuity testing is performed with a test current above 200mA, covering a range from 0.05Ω to 199Ω for reliable earth verification.
What sets the PV:1525-IV apart is its advanced I-V curve tracing capability. The tester displays a full graphical I-V curve directly on screen and calculates key performance parameters, including maximum power point voltage (Vmpp), maximum power point current (Impp), and fill factor. This provides a detailed understanding of PV string performance, enabling engineers to pinpoint inefficiencies and verify system output with confidence.
Seaward PV:1525 1500V Innovative New Interface
The Seaward PV:1525-IV has been carefully designed with user-experience in mind, featuring an intuitive interface, illuminated function buttons (allowing for guided navigation and testing as well as better visibility in low-light conditions), an 88.9mm (3.5 inch) colour screen display, and built-in memory that can store up to 1000 test records. With integrated Bluetooth connectivity, solar professionals can enjoy seamless and efficient data transfer to the Seaward PV Mobile App, which supports result tagging, cloud syncing, and wireless firmware updates to keep the unit updated with the latest features.
Unlike its predecessors that relied on AA batteries for power, the PV:1525-IV uses a rechargeable 11.55V 2930mAh LiPo battery, giving users hours of extended operation on the go, and comes complete with accessories such as 4 mm test probes, MC4-compatible leads, the PV:1500 wireless clamp meter, a solar panel clamp, and a carry case. It also includes a LiPo battery pack, battery charger, quick start guide and the SolarCerts pack to support full system documentation.
Seaward PV Mobile App
The Seaward PV Mobile App is free to download on compatible Android and iOS devices. It enables wireless data transfer from the Seaward PV:1525-IV to a smartphone via Bluetooth, eliminating the need for manual result logging. The PV mobile app also supports wireless firmware upgrades, ensuring the solar tester remains up to date with the latest features and improvements.
With the app, users can view I-V and power curves in full colour and high definition directly in the field, supporting fast and accurate visual analysis. This helps identify common issues such as shading, defective cells, or poor electrical connections. Using irradiance and temperature data from the Seaward SS200LR, the app allows for I-V curve correction to standard test conditions (STC: 1000 W/m², 25°C), enabling more accurate comparisons with the manufacturer's data
