6 Frequently Asked Questions about “Photovoltaic low voltage to medium voltage inverter”
What is a high voltage PV string inverter?
Higher voltage reduces the cable cross section. The inverter developed by Fraunhofer ISE enables the transition of PV from low voltage to medium voltage. Modern PV string inverters have an output voltage of between 400 V AC and 800 V AC. Although the output of power plants is steadily growing, voltage has not yet been increased.
Can PV inverters handle higher voltage levels?
By feeding power into the medium-voltage grid, the “MS-LeiKra” project team has demonstrated that PV inverters are technically capable of handling higher voltage levels. The benefits for photovoltaics in-clude enormous cost and resource savings for passive components and cables.
Can a string inverter handle higher voltages?
The Fraunhofer Institute for Solar Energy Systems ISE has developed and suc-cessfully commissioned the world's first medium-voltage string inverter for large-scale power plants. By feeding power into the medium-voltage grid, the “MS-LeiKra” project team has demonstrated that PV inverters are technically capable of handling higher voltage levels.
What is the output voltage of a PV string inverter?
Modern PV string inverters have an output voltage of between 400 V AC and 800 V AC. Although the output of power plants is steadily growing, voltage has not yet been increased. There are two reasons for this: First, building a highly efficient and compact inverter based on silicon semiconductors is a challenge.
How many kV can a sic inverter produce?
SiC components up to 3.3 kV are now available on the market. In 2023, Fraunhofer ISE developed the world's first medium-voltage photovoltaic (MS-PV) string inverter in the "MS-LeiKra" project and successfully put it into operation on the grid. The two-stage inverter has an output voltage of 1,500 V AC at a power of 250 kVA.
Can a high-voltage solar power plant save raw materials?
One promising approach to save raw materials is to move from the low to the medium-voltage level in renewable energy power plants. The Fraunhofer Institute for Solar Energy Systems ISE sees a huge potential for savings with higher system voltages, especially in large PV power plants.
