I-V curve tracer (PV analyzer) 'Epsilon 1000'-PVA14300R-
Solar cell strings with a system voltage of up to 1000V can be measured. Reliable I-V measurement with a linear sweep within 200 [ms]!
This is an I-V curve tracer compatible with the voltage range of 1000V, suitable for many residential and industrial solar power generation systems. It is an I-V curve tracer for solar cell strings that supports 1000V/30A. The functionality has been significantly renewed from the old PVA14300 model! It can store up to 9999 data points in internal memory, displays results in about 1 second, and allows for short-duration measurements that are less affected by sudden changes in sunlight or shading. 【Features】 - Capable of measuring 1000[V] and 30[A] (can also measure ultra-high output modules such as parallel strings and bifacial modules) - Measurement interval shortened to 5-12 seconds (varies depending on the measurement target) - Equipped with an automatic measurement function (manual/automatic selection available) - Added Japanese mode to the operation guide (English option also available) - Safe operation with reverse connection detection function (misuse detection) - Internal data storage capacity of 9999 points, suitable for large-scale power plants.

Our new I-V curve tracer can measure "high-efficiency solar cells" such as N-type, half-cut cells, and N-type back contact.
In recent years, there have been reports of cases where high-efficiency solar cells (such as N-type and half-cut cells) cannot measure I-V curves using competitor products or the old Epsilon 1000 (PVA14300). However, measurement is possible with the current Epsilon 1000 (PVA14300R) and Epsilon 1500 (PVA18340). Both the current and old models of Epsilon have a built-in overcurrent detection circuit, which prevents equipment failure by cutting off the current and stopping I-V curve measurement if the measurable current exceeds 30 [A] (when overcurrent is detected). High-efficiency solar cells tend to have a large inrush current flowing into the Epsilon, leading to a higher frequency of measurement stoppages due to overcurrent detection with the old Epsilon. Even if the catalog value of the solar cell is around 15 [A], the actual output current can momentarily exceed 30 [A] significantly. The current Epsilon is equipped with an inrush current prevention circuit that performs gradual short-circuit processing. This suppresses the occurrence of overcurrent during short circuits, making measurement possible even when the capacitive component of the PV is large. Measurement is also possible with the Gamma series and Delta.
