Wireless environmental sensor for solar PV diagnostics. Measures solar irradiance (0–2,000 W/m², Apogee SP-110-SS), module temperature, and ambient temperature simultaneously. Bluetooth-connected with automatic cloud sync alongside Z300 PVT string test results.

1500V photovoltaic tester for conventional and PERC module strings. Measures Voc, Isc, Riso (0–99 MΩ), Rs, and locates ground faults. Bluetooth app-controlled with real-time cloud sync.

1500V photovoltaic tester for high-efficiency and bifacial modules. Measures Voc, Isc, Riso (0–99 MΩ), Rs, Vmp, Imp, and Pmax via rudimentary IV curve sweep. Inrush current protection for TOPCon and HJT strings. Bluetooth app-controlled with real-time cloud sync.

Compact solar irradiance and temperature meter for PV commissioning and O&M. Measures plane-of-array irradiance (W/m²), PV module temperature, and ambient temperature. Built-in inclination sensor and compass. LoRa interface for long-range sync with PVM-1530. reSYNC data gap recovery. Standalone datalogger with 5000-record memory. IP65.

2,500 V insulation resistance meter measuring up to 2 TΩ — four to ten times the ceiling of comparable Fluke and Megger instruments. Features a 5-inch color capacitive touchscreen with live Riso/leakage charting, IP65, Wi-Fi/Bluetooth/USB-C, EPA mode for ESD-protected zones, SPD testing, and PI/DAR absorption timing. A serious but underappreciated alternative at a competitive price.

Professional multifunction photovoltaic meter for 1500V systems. Covers IV curve tracing (IEC 62446-1 Cat. 2), Voc, Isc, insulation resistance at four test voltages with simultaneous RISO+/RISO−, bypass and blocking diode testing, continuity, and AC/DC measurements. Automatic STC correction via IRM-1 sensor per IEC 60891. reSYNC function, large colour touchscreen, Bluetooth/Wi-Fi/USB connectivity.

The fastest capacitive IV curve tracer on the market — up to 200 curves per hour at ±0.5% accuracy at Pmax. Covers modules and strings to 1500V and 35A per IEC 61829. Includes E-Sens wireless sensor with 2 km range for irradiance and temperature. Bifacial albedo support with dual reference cells. Barcode reader, PVET cloud integration, smartphone app control.

DIN-rail datalogger for reference PV modules — measures Isc and Voc of a reference module, calculates irradiance and cell temperature, outputs directly to SCADA via Modbus. Avoids hot-spot-inducing permanent short circuits. E-Ref/01 for monofacial; E-Ref/03 for bifacial (front + rear irradiance + temperature, 3 channels).

Wireless irradiance and temperature sensor for the E-1500 and E-1000 IV curve tracers. 2 km wireless range — place once and walk the full array. Connects to a calibrated reference cell; transmits Geff and module temperature to the tracer for automatic IEC 60891 STC correction. Supports up to three Pt1000 probes and includes an onboard display.

Soiling sensor that quantifies PV plant dirt losses at Pmax — not just Isc. Compares maximum power between clean and soiled reference modules to capture non-uniform soiling, bypass diode effects, and angular incidence variation. Sub-minute sampling. IEC 61724-1 compliant. Online platform with daily, weekly, and annual soiling pattern analysis for cleaning campaign optimisation.
