According to the scale development goals provided by the National Power Administration, my country’s installed solar power generation capacity will reach 160 million kilowatts in 2020, and the annual power generation capacity will reach 170 billion kilowatt-hours. Photovoltaic is the fastest growing power variety in the world. The power and reliable operation of the photovoltaic inverter as the center directly affects the power generation and benefits of the power station!

The GB/T30427-2013 “Technical Requirements and Experimental Methods for Special Inverters for Grid-connected Photovoltaic Power Generation” issued by the General Administration of Quality Supervision, Inspection and Quarantine at the end of 2013 provides a test for grid-connected photovoltaic power inverters with an AC output terminal voltage not exceeding 400V. Skill requirements and experimental methods.

The conversion power of the general photovoltaic inverter can reach more than 96%, but this parameter is the test data of the manufacturer in the laboratory under imitating the load condition. The load factor, input voltage, environment and other influences, the power is changed.
