Regatron G5.SAS - Solar Array (PV) Simulators


TestREGATRON's versatile and modular PV Simulators are known to fully meet the stringent requirements of various user groups such as solar inverter manufacturers, scientific institutes, engineering service providers, grid operators, testing laboratories, and certification and approval providers. Power inverter development, production testing, and laboratory use are equally important areas of application.


Like real solar arrays, the DC power supplies of the G5.SAS series are unidirectional sources. With the special requirements of solar array simulation in mind, these power supply units feature especially low capacitance values in the output filter stage and switchable earth leakage resistors for adaptation to the insulation measurement of the DUT. The very high resolution of voltage and current, as well as the high system dynamics, enable precise maintaining of the phase conditions and thus a realistic simulation.


The powerful application software SASControl opens up convenient possibilities both for the definition of specific array curves and for the live-assessment of static and dynamic MPP tracking. I-V curves are calculated with high accuracy in real time. SASControl fully complies with the efficiency measurement procedures for maximum power point tracking (MPPT) in solar inverters as described in EN 50530. Core to the application software SASControl is a versatile script programming system which allows the easy implementation of individual programming sequences. Report generation of measured data is included.


REGATRON also offers the appropriate test equipment for the mains side of the solar inverter to be developed/tested: The Grid Simulators of the TC.ACS series are full 4-quadrant regenerative 3-phase AC sources. Starting at a power level of 30 kVA, complete DC & AC testing solutions can be offered. Click here for more information about REGATRON's modular TC.ACS series.


G5.SAS Solar Array Simulators range from 0...18 kW to 0...2400+ kW, up to 1500 VDC. Higher voltages are available. REGATRON's modular concept allows the system to be easily adapted to ever changing test requirements. Not only is it possible to reconfigure between parallel, series, and mixed operation, but also to expand the system with additional power supply units or to split it into smaller units. Therefore, the purchase of a REGATRON PV Simulator is a solid investment for the future.
