Seaward PV:1525 Solar PV Tester
Built for modern solar testing, the Seaward PV:1525 Solar PV Tester helps engineers check photovoltaic systems during commissioning, service and fault finding. It supports high voltage DC work up to 1500 V, so it suits demanding solar sites. Its compact design also helps users move between panels and test points with less delay.
This tester gives clear checks for core PV safety tasks. Users can measure open circuit voltage, short circuit current, insulation resistance and earth continuity. As a result, it supports safe acceptance testing for both residential and commercial solar systems.
Safe PV testing
Live input warnings help protect the user during testing. The Seaward PV:1525 Solar PV Tester also includes automatic test inhibition when live input is detected. Therefore, it helps reduce risk while working on high energy solar circuits.
Measurement performance supports detailed site checks. Open circuit voltage testing covers up to 1500 V DC, while short circuit current testing covers up to 25 A DC. In addition, insulation resistance tests use selectable voltages up to 1500 V.
Data and field use
Bluetooth connectivity links the unit with the PV mobile app for data transfer and firmware updates. Onboard memory stores test results, helping engineers keep records during larger jobs. A 3.5 inch backlit colour screen also helps in bright daylight and darker work areas.
Weighing 1 kg, the Seaward PV:1525 Solar PV Tester is easy to carry across a site. It uses a rechargeable LiPo battery pack and comes with a battery charger. Supplied leads and probes support common solar test tasks straight from the box.
