Applications
Grid Simulator Power Supply, the solar cell simulator and power analyzer forming the inverter test system (Solar cell AN51 series solar cell simulator, PV inverter AN87500 multi-channel power analyzer, load ANGS series Grid Simulator Power Supply).

The ANGS series Grid Simulator Power Supply can simulate overvoltage/undervoltage, over-frequency/under-frequency, low (zero) voltage ride through and other curves. The overvoltage/undervoltage, over-frequency/under-frequency, anti-islanding protection of inverter can be tested with anti-islanding load or AC electronic load. AN51 series solar cell simulator can simulate a variety of I-V curves of solar cell to verify the inverter's maximum power tracking capability, and conduct inverter aging test and overvoltage/undervoltage protection; AN87500 multi-channel power analyzer can analyze the inverter’s power, harmonics, efficiency and other parameters, so as to conduct comprehensive analysis of inverter performance. Three kinds of equipment can be integrated using professional PC test software to form a comprehensive inverter test system and solutions.

Grid Simulator Power Supply output high-voltage DC, conducting loop test combing with the inverter (ANGS series Grid Simulator Power Supply, DC output, PV inverter, AC output)

The DC output terminal of ANGS series Grid Simulator Power Supply is connected to the DC input terminal of the inverter. The DC output terminal of the inverter is connected with the output terminal of the Grid Simulator Power Supply in parallel to form a loop test. The energy flows in the loop, saving equipment investment for some specific tests.
