Seaward PV:1525-IV Solar PV Test Kit
The Seaward PV:1525-IV Solar PV Test Kit helps installers and O&M teams test solar PV systems with speed and detail. It supports commissioning, inspection, fault finding, and maintenance work on residential, commercial, and large PV sites. Users can carry out electrical safety tests and performance checks with one field-ready kit.
This tester handles PV installations up to 1500 V DC and 25 A DC. It checks key values such as open-circuit voltage, short-circuit current, insulation resistance, and continuity. Therefore, users can confirm safe system operation while also gathering data for deeper analysis.
Advanced PV test capability
The Seaward PV:1525-IV Solar PV Test Kit includes integrated I-V curve tracing for detailed PV string checks. It displays a full graphical I-V curve on the colour screen, so users can view results directly in the field. It also calculates maximum power point voltage, maximum power point current, maximum power output, and fill factor.
These readings help users find issues such as shading, poor connections, mismatch, defective cells, and module degradation. In addition, the tester can use irradiance and temperature data for I-V curve correction to standard test conditions. This helps users compare measured results with manufacturer data more accurately.
Connected working in the field
The Seaward PV:1525-IV Solar PV Test Kit works with the Seaward PV Mobile App through Bluetooth. Users can transfer results to a smartphone, tag results, sync data to the cloud, and apply wireless firmware updates. As a result, the tool reduces manual logging and helps keep the unit up to date.
A rechargeable 11.55 V 2930 mAh LiPo battery powers the unit for extended site work. The kit also includes accessories such as MC4 test leads, test probes, a clamp meter, an irradiance meter, a solar panel clamp, and a carry case. With onboard storage for up to 1000 test records, the Seaward PV:1525-IV Solar PV Test Kit supports clear records from field test to report.
