The E-1500 sweeps the I-V curve of a module or string in milliseconds and is ready for the next one within seconds, so a single operator can measure up to 200 curves per hour. With the irradiance and temperature sent by radio from the wireless E-Sens sensor, each curve is translated to STC (1,000 W/m² and 25 °C) following IEC 60891:2021, with 0.5 % accuracy at the maximum power point.
It covers strings up to 1,500 V and 35 A, measures bifacial modules with up to three reference cells (one front and two rear, as recommended by IEC TS 60904-1-2) and works hands-free from its transport backpack. Every purchase includes free, lifelong access to PVET, the platform that processes the curves, detects faults and generates reports automatically.
E-1500 with calibration certificate · E-Sens wireless sensor with antenna · calibrated reference cell · PT1000 temperature probe · four-wire measurement leads with MC4 · MC4-to-crocodile adapter · 1,500 V in-line fuse holder · SD and microSD cards · transport backpack · 2-year warranty and PVET access.
Bifacial compatibility (additional reference cell) · E-Temp wireless infrared thermometer · barcode reader · additional PT1000 probes · additional MC4 measurement leads · Peli hard case. The tracer is also available on its own (Tracer Only).
Every minute, the E-Dust compares the full I-V curves of two identical modules, one kept clean and one left to soil like the plant, and returns the soiling ratio at the maximum power point, as defined in IEC 61724-1.
The E-Ref measures the short-circuit current and open-circuit voltage of a reference module of the same type as the plant's, and delivers irradiance and cell temperature to the SCADA by Modbus, with no further conversion. Versions for monofacial and bifacial modules.
Handheld tester for essential safety and commissioning tests on PV systems up to 1500 V DC and 25 A, with I-V curve tracing.
