Elgar TerraSAS Programmable Photovoltaic Solar Array Simulator

The Elgar TerraSAS (TSAS) Programmable Photovoltaic Solar Array Simulator is engineered for precise simulation of solar array behaviors. Designed for solar applications, the TerraSAS enables comprehensive testing and development of PV inverters, charge controllers, and other solar conversion devices. It accurately mimics the I-V characteristics of various solar panels under changing environmental conditions, such as light intensity, temperature, and shading. Supporting programmable profiles to replicate dynamic solar conditions, the TerraSAS provides fast response in critical assessments of how devices adapt to sudden shifts in solar irradiance. This makes it invaluable for MPPT algorithm testing and inverter efficiency evaluations.

Hardware control can be managed through running an application hosted on the local controller, which directly interfaces with the PV simulator via RS422 for IV curve generation processing. The system’s GUI is provided through a separate application, granting users complete control over the TerraSAS system. This application includes an Ethernet (LAN) parser, enabling remote communication and control. All functionalities accessible through the local controller can also be managed remotely.
