The following product testing solutions are available:
①、Programmable Bidirectional DC Power Supply: Can simulate solar cells and also act as a load to achieve integration of source and load. It absorbs power and feeds it back to the grid cleanly at the same time.
②、Grid-Feedback Simulated Power Supply (AC Source): Can simulate various operating conditions such as grid voltage, frequency fluctuation, unbalanced output, etc. It can inject harmonics and inter-harmonics, while absorbing power and feeding it back to the grid cleanly.
③、High-Precision Power Analyzer: Can perform multi-channel measurement of conventional parameters such as input and output voltage, current, power of PCS inverter, as well as harmonic distortion, harmonic content of each order, etc.
④、Comprehensive Safety Performance Analyzer (Safety Tester): Features wide range and high precision, supporting 10kV AC/DC withstand voltage/insulation test and 100A DC grounding test, which meets the comprehensive safety test requirements of PCS components and inverters.
⑤、Oscilloscope: Can perform multi-channel measurement of input and output waveforms, monitor the output quality of PCS inverter, and measure parameters such as frequency and THD……
