Seaward PV:1525-IV Solar PV Tester & I-V Curve Tracer
The Seaward PV:1525-IV Solar PV Tester & I-V Curve Tracer helps installers and engineers test solar PV systems with speed and care. It carries out electrical safety checks, performance tests, and I-V curve tracing in one field-ready unit. As a result, users can check safety and system output without using several separate tools.
This tester supports work on residential, commercial, and larger PV systems. It measures PV installations up to 1500 V DC and 25 A DC, so it suits high power solar work. In addition, it helps teams meet IEC 62446 and IEC 61557 test needs.
Electrical Safety Testing
Safety checks include continuity, insulation resistance, open-circuit voltage, and short-circuit current. The Seaward PV:1525-IV Solar PV Tester & I-V Curve Tracer also warns users about dangerous voltages at terminals. Therefore, engineers can work with better awareness during commissioning and fault checks.
The unit measures insulation test voltages of 250 V, 500 V, 1000 V, and 1500 V DC. It also measures earth continuity with a test current greater than 200 mA. These tests help users find faults, prove safe operation, and record key results on site.
I-V Curve Analysis
I-V curve tracing gives a clear view of PV string performance. The tester shows the curve on screen and calculates values such as maximum power point voltage, maximum power point current, and fill factor. In addition, the app supports STC correction when used with irradiance and temperature data from the Seaward SS200LR.
Bluetooth connectivity helps move results to the Seaward PV mobile app. Users can tag results, sync data to the cloud, and update firmware wirelessly. Overall, the Seaward PV:1525-IV Solar PV Tester & I-V Curve Tracer gives PV teams a strong tool for testing, fault diagnosis, and performance checks.
