ETS Series Standalone Photovoltaic Simulator


AMETEK Programmable Power has expanded its Elgar TerraSASTM line with the ETS Series Standalone Photovoltaic (PV) Simulator. The new Series includes three models for testing PV inverters across a wide spectrum of applications:

  • ETS 80 to test micro-inverters or DC optimizers up to 80Vdc Voc
  • ETS 600 for testing string inverters that contain transformer isolation up to 600Vdc Voc
  • ETS 1000 for non-isolated string inverters up to 1000Vdc Voc.

For microgrids, energy storage, and inverter test applications, TerraSAS PV Simulators are specifically designed to emulate the dynamic electrical behavior of a terrestrial PV solar array.  They offer low output capacitance and high closed loop bandwidth to keep up with the advanced Maximum Power Point Tracking (MPPT) algorithms used in today's grid-tied inverters.

The Elgar TerraSAS and ETS Series PV simulators are based on high-speed versions of Elgar power supplies, where output capacitors, advanced DSP signal processing techniques, and other speed-limiting components have been adjusted to create a proprietary solution more advanced than any other solar array simulator on the market. This combination of hardware, software, and firmware allows the TerraSAS to simulate test protocols or combinations of events that a real-world solar installation is subjected to.
