ITECH IT-N2100 Solar Array Simulator for MPPT and PV Inverter Testing
PV Simulator for Static and Dynamic I-V Curves
The ITECH IT-N2100 is a programmable solar array simulator for reproducing static and dynamic I-V curves of PV modules and solar arrays. It enables microinverters, power optimizers, and PV inputs of energy storage systems to be tested independently of actual weather conditions. Irradiance, temperature, and shading can be simulated under controlled conditions for reproducible testing of MPPT tracking, MPPT efficiency, and device functionality.
The PV simulator supports MPPT tracking rates up to 250 Hz and accurately follows the specified I-V curve even during rapid operating-point changes. Table mode supports up to 4,096 data points. Static and dynamic shading curves can also be simulated. Low output current ripple helps minimize the influence of the source on current sampling and MPPT evaluation.
Five PV modes cover user-defined curves, LIST sequences, built-in models, fixed mode, and table mode. Tests according to EN 50530, Sandia, NB/T 32004, CGC/GF004, and CGC/GF035 can be performed and documented using the solar array simulation software. Up to 20 channels can be controlled synchronously. Depending on the model, output ratings of 80 V or 150 V, up to 25 A, and 800 W or 1,500 W are available.
