The smallest, lightest and fastest I-V curve tracer on the market. Up to 200 curves per hour on modules and strings, bifacial included, with every curve translated to standard test conditions (STC) on the spot.
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.
