Solar panel currents have been steadily increasing with the introduction of larger, higher-powered and bifacial modules—particularly on commercial installations. Combine this with the growing use of module-level power electronics, including optimisers and rapid shutdown devices, and testing modern solar PV systems is becoming increasingly challenging.
The PVCHECKs- ONE manufactured by HT Instruments is designed to simplify the process. It can test PV strings up to 1000V and 30A, perform insulation-resistance testing on installations fitted with optimisers or rapid shutdown devices, and help pinpoint ground faults—all from a single instrument.
Available in the UK from Test Instrument Solutions (TIS), it could become the go-to solar PV tester for installers working across residential and commercial systems.
