The Seaward PV:1525 is a robust handheld measuring device for installers and maintenance technicians to perform electrical safety tests and performance measurements on photovoltaic systems quickly, safely, and in accordance with standards. Typical applications include commissioning, maintenance, and troubleshooting of PV strings in residential and commercial installations. An intuitive interface with a color display, illuminated function keys, and guided navigation speeds up testing procedures. Measurement data can be stored internally and conveniently transferred to the PV:Sync Mobile App via Bluetooth. OTA updates keep the device automatically up to date.
The PV:1525 measures open-circuit voltage (Voc) up to 1,500 V DC, short-circuit current (Isc) up to 25 A DC, performs insulation resistance and protective conductor continuity tests, and supports optional accessory sensors (PV:1500 Clamp, SS:200LR Irradiance Meter) for extended power and irradiance measurements.
