Power electronics test solutions for photovoltaic (PV) inverters
62000H-S Series Programmable DC Power Supply: replaces the DC output of solar panels and also features the unique capability to simulate the I-V curve of solar panels. This feature is used to evaluate the performance of PV inverters for maximum power point tracking (MPPT) testing.
61800 Series Regenerative Grid Simulator Power Supply: a dual-purpose instrument that can simulate the grid and serve as an AC load at the same time. It can simulate various voltage and frequency outputs, making it suitable for testing the grid-connected functionality of inverters. For standalone PV inverters, the 61800 series can operate in a four-quadrant AC load mode, simulating capacitive loads with leading phase current or inductive loads with lagging phase current. It can also recycle the output energy during the testing process.
66200 Series Digital Power Meter: can measure various parameters of the output of PV inverters, such as voltage, current, power, power factor, harmonic components of each phase, and total harmonic distortion.
Optimized Test Items
The optimized test item covers 5 types of power supply test requirements. The Output Performance test verifies the output characteristics of the UUT. The Input Characteristic test checks the UUT input parameters. Timing & Transient tests the timing and transient states during protection. The Protection TESTS trigger and test the protection circuit, the Special Test provides means to test the most sophisticated UUT when unique test routines are needed.
*The RLC load is required. This system can test automatically and meet regulations of multiple anti-islanding protection test conditions to save test time. It not only fits R&D and QC, but also very suitable for production line.
