High response speed：

Photovoltaic simulator has a current loop speed of up to 500kHz and supports 250Hz MPPT speed.Its IV curve consists of up to 4096 data points which closely matches the real output of the photovoltaic array. The real output of the photovoltaicpanel strictly follows its IV curve.When the MPPT tracking frequency increases, if the response speed of the simulator (power supply) is too slow, it will not be able to track the IVcurve, and the reliability of the test results is under doubt. Under the condition of high MPPT tracking frequency of the solar array simulator series PV simulator,the output still accurately conforms to the preset IV curve.

Low noise of output current：

The high fundamental frequency noise of the PV simulator affects theMPPT and current sampling precision of the inverter.

5 PV modes

Solar Array Simulator series has 5 built-in PV modes. You can operate it on the front panel. With the built-in IV curves models of multiple regulations, four-pointmethod, table tracing point method, fixed mode or list programming, it can simulate the output of solar array IV curve, big screen graphical display,and real-time view of MPPT status of micro-inverter, power optimizer and other DUTs. In addition, you can import model files via a USB. Whenmultiple channels operations are required, you can use PV software, very convenient.
