Applications

The ANBGS 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.

1.Grid Simulator Power Supply, the solar cell simulator and power analyzer forming the inverter test system.

2.Low (zero) voltage ride through

3.Harmonic mode
