Simulating PV arrays to test MPPT algorithms and circuits

Testing PV inverters requires engineers to verify the performance of the inverter’s maximum power point tracking (MPPT) algorithms and circuits. MPPT algorithms are complex, and under-the-sun testing at different temperatures and irradiance conditions is difficult, expensive, and time-consuming. The engineers also need to load and measure the output power of the PV inverter.

Escape the unpredictability of local weather conditions by using a PV / solar array simulator. Use a programmable DC power source to help simulate real-world PV / solar arrays, and test them against various environmental factors such as temperature, irradiance, age, and cell technology. Make sure to test the inverters according to the industry standards, such as EN50530, which provides a procedure for measuring the efficiency of MPPT. Use an AC / grid emulator to load and test the inverter’s output.

PV inverter test solution

Verifying the performance of PV inverters under varying weather and load conditions requires simulating solar arrays in the lab and AC / grid. With the Keysight solar array simulator and software, engineers can test up to 12 MPPT channels simultaneously and perform complex static and dynamic EN50530 tests automatically with just a few clicks. The Keysight SL1200A regenerative AC / grid emulators enable proper loading of the output of the PV inverter and measurement of output power.
