The Elgar brand TerraSAS Solar Array Simulator from AMETEK Programmable Power offers a fully integrated solution for the design, development and production testing of inverters and micro-inverters for domestic and industrial solar energy systems. The TerraSAS simulates photovoltaic (PV) dynamic solar irradiance and temperature characteristics over a range of weather conditions from clear to cloudy and over a specified time interval to produce the current / voltage (IV) characteristics for the specified PV array for those conditions.
For ease of use, the system ‘s simulation engine is able to download data from the National Renewable Energy Laboratory (NREL) Solar Advisor Model database defining key parameters – open circuit voltage (Voc), short circuit current (Isc) and maximum power point voltage (Vmpp) at 25 degrees C and 1000 W/m2 irradiance – so that the IV curve can be calculated acco rding to a standard solar cell model for virtually any fill factor or solar material. Other PV panel IV curves can beentered manually .
Systems with multiple panels with different characteristics resul t ing in multiplehump IV curves also can be simulated. In addition, the TerraSAS is capable of simultaneously simulating up to 24 parallel channels for use with micro-inverters.
