The Elgar ETS1000X10E Standalone TerraSAS Photovoltaic Simulator 480 VAC, 10kW consists of a high performance, programmable DC power supply with control software and GUI interface, output isolation, and a unique PV simulation engine that provides the I-V curve. This combination of hardware, software, and firmware allows the TerraSAS to simulate test protocols or combinations of events that a real-world solar installation will be subjected to. The included software allows modeling of a PV panel without an extensive knowledge of solar array parameters.

The only parameters required for a simulation are the open circuit voltage (Voc), short circuit current (Isc), and the peak power parameters Vmp and Imp. Changes to these parameters allow the shape of the I-V curve to be adapted to any fill factor between 0.5 and 0.95. Once an I-V curve has been generated, changes to the irradiation level or temperature can be modified on the fly to test the behavior of a grid tied inverter under realistic conditions for cloud shadowing and panel temperature rise. Long term weather simulations can be loaded and run to determine the amount of energy harvest delivered in a given situation. Inverter designers use these accuracy and efficiency tests to optimize real MPP search modes. The ETS1000X10E is compliant with IEC 61010-1.
