The Seaward PV:1525 is a robust hand-held measuring device for installers and maintenance technicians to carry out electrical safety tests and power measurements on photovoltaic systems quickly, safely and in accordance with standards. Typical applications include commissioning, maintenance and troubleshooting on PV strings in private and commercial installations. An intuitive interface with a color display, illuminated function keys and guided navigation speeds up the test 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.
