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 80 Vdc Voc
- ETS 600 for testing string inverters that contain transformer isolation up to 600 Vdc Voc
- ETS 1000 for non-isolated string inverters up to 1000 Vdc Voc.
The ETS 600 and ETS 1000 are 3U rack units, while the ETS 80 comes in a 1U package. The ETS 80 also is cost effective, being 30 to 40 percent less expensive than units with comparable output specifications.
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.
All Elgar ETS Series units are high-performance solutions packaged in a small form factor that combine an agile power supply, an innovative I-V curve generator, output isolation and Graphical User Interface (GUI) in a single, standalone unit.
