Terrestrial Solar Inverter Design Using Solar Array Simulators
应用文章
Terrestrial solar inverter manufacturers must ensure that their products are capable of extracting and delivering all the power that is available from the photovoltaic solar modules to which they are attached. Power available from a solar module is highly dependent on its illumination and temperature. The maximum available power is known as the maximum power point (MPP). The MPP changes with operating conditions. For inverter design, development and qualification purposes, it is necessary to test with an array of MPPs. Obtaining a full range of MPPs from a solar module requires exposure to a broad range of illumination and temperature for extended periods, which is not practical in the test environment with a solar module. This measurement tip discusses solar array simulation as a test solution.
