EKO รุ่นMP-11อุปกรณ์วินิจฉัยความล้มเหลวในการประเมินเซลล์แสงอาทิตย์Hidehiro Seiki IV Checker MP-11[Solar cell evaluation failure diagnostic device]

Hard to be affected by changes in sunlight and shadows

By having a fast sweep time of tens to hundreds of ms or less, measurement errors due to changes in sunlight and shadows are minimized. *

Easy failure judgment

The IV checker MP-11 is less susceptible to the effects of the external environment, making it easier to find defective panels. *

Improved accuracy of data measurement

The "reverse bias function" has been newly implemented from the IV checker MP-11. This greatly improves the data measurement accuracy on the current axis side. *

Large capacity 18kW for mega solar

The maximum value of the measurement range of IV checker MP-11 is 1000V / 30A / 18kW, and it is also compatible with mega solar.

Intuitive operation

IV checker MP-11 dedicated key enables easy measurement.

Speedy

It takes about 5 seconds from pressing the measurement button to displaying the result. Continuous measurement is possible at 35 second intervals.

Equipped with pyranometer as standard

The sensor unit for solar radiation measurement is equipped with a silicon pyranometer that is traceable to the world radiation standard.

All-in-one

All parts attached to the IV checker MP-11 can be stored in the main body.

Applications of EKO Eiko Seiki IV Checker MP-11 [Solar Cell Evaluation Failure Diagnosis Device]

For inspection, regular maintenance, failure diagnosis, etc. during and after construction of a solar power plant.
IV Checker MP-11 Reliability of measurement data

Hard to be affected by sunlight and shadows

It is common for solar radiation changes to change by a few percent to a few tens of percent in a few seconds.
The longer the actual sweep time, the more susceptible it is to changes in solar radiation.
The graph on the left shows the case where the sweep time is 5 seconds, but in the IV checker with a long sweep time, it can be seen that the change in solar radiation during this period has a great influence on the IV curve.
MP-11 has a short sweep time of tens to hundreds of ms, and it can be said that there is almost no effect during this period.

Easy failure judgment

If the IV checker with a long sweep time produces a measurement result like the one on the right, it is difficult to determine whether this is due to a change in solar radiation or a malfunction.
However, MP-11, which has a short sweep time, is less susceptible to changes in solar radiation, so it is possible to determine that it is due to some kind of failure (or the effect of shadows).

Improved accuracy of data measurement

The MP-11 is newly equipped with a reverse bias function.
The blue line in the figure on the left shows the measurement data of our IV checker with the conventional model.
You can see that MP-11 in the red line can measure data from the current axis.
The accuracy on the current axis side has been improved, enabling highly reliable measurement.
