[Case Study] Testing System for Grid-Connected Inverters for Solar Power Generation

Check whether the inverter's protection function operates within the specified range for abnormalities occurring in the system!

We would like to introduce a case where our "Wave Researcher" was delivered to a solar power grid-connected inverter testing system. The testing of solar power grid-connected inverter devices is generally conducted in accordance with the method outlined in the "Testing Methods for Grid-Connected Protection Devices for Small Solar Power Generation Systems." In this case, we used power meters "WT230" and "WT1600," along with "DL750" for waveform analysis, and a simulated power supply to measure and analyze test data. 【Processing Details】 ■ Control a power supply that simulates solar panels to input DC voltage into the inverter device being tested. ■ Measure the AC output from the inverter, as well as the voltage, current values, frequency, and harmonics of the grid-simulated power supply using power meters. ■ Observe the operational status of the inverter's protection functions and the waveforms of the inverter output voltage and current. ■ Prepare a test report based on the test results. *For more details, please refer to the PDF document or feel free to contact us.
