MP-170S EKO Instruments I-V Checker Sensor Unit

The EKO Instruments MP-170 I-V Checker Portable I-V Curve Tracer is designed to measure DC output from a PV array or module. Purposes of measurement include evaluation, checking system failures, and maintenance of the PV power system. MP-170 uses capacitor load method to measure the I-V curve which makes high power measurements possible. Compact size, high performance and accuracy are achieved from EKO's long experiences in PV measurement.

The EKO Instruments MP-170 I-V Checker Portable I-V Curve Tracer consists of the Main unit and the Sensor unit. The Main unit is not only capable of taking measurement, showing graph, and analyzing data by key pad operation, it can also transfer the measured data to the PC by connecting with USB and analyze data on the PC by using the MP-170 software.

Also, the Sensor unit has a built-in Si-pyranometer, and this allows the measurement of incident solar irradiance and the back-side temperature of the PV module while measuring the I-V curve on the Main unit at the same time; this makes the conversion for Standard Test Condition (STC) complying with JIS C8914 standard easy. Also, the external input terminal on the Sensor unit can be connected with not only EKO pyranometers (MS-802, MS-402, and MS-601), reference cell, and/or thermocouple, and the data can be stored.

The Main unit and the Sensor unit can transfer the data by connecting with modular cable; the solar irradiance data and temperature data measured on the Sensor unit can be transferred to the Main unit.
