Product Overview: PV:1525 Handheld 1500 V 25 A PV Tester

The PV:1525 is a professional handheld test instrument designed for installers and maintenance technicians. It performs comprehensive electrical safety tests and performance measurements on photovoltaic (PV) systems up to 1500 V DC and 25 A DC, making it ideal for both residential and commercial installations.
Key Measurement Functions:
Open Circuit Voltage (Voc) Measurement: For PV strings up to 1500 V DC.
Short Circuit Current (Isc) Measurement: For PV strings up to 25 A DC.
Insulation Resistance Testing: At test voltages of 250 V, 500 V, 1000 V, and 1500 V DC.
Protective Conductor Continuity Testing: With a test current >200 mA at 2 Ω.
Operating Current & Power Measurement: (When used wirelessly with the optional PV:1500 Clamp) Current from 0.1 A to 400.0 A DC, power from 0.50 kW to 600 kW.
Main Features:
Modern User Interface: Features an intuitive color display and illuminated function keys for guided navigation and testing.
Bluetooth® & PV:Sync Mobile App: Enables easy wireless transfer of test results to the iOS and Android™ PV:Sync Mobile app for review and export to SolarCert PC software.
Wireless Over-the-Air Updates: Firmware updates can be delivered via the mobile app, keeping the device's functionality current.
Internal Memory: Stores up to 1000 test results with configurable site/asset information.
Diagnostic Manual Mode: For custom diagnostic testing procedures.
Safety: Visual and audible warnings, plus circuit protection that stops testing if ≥30 V AC/DC is detected at the inputs.
