Application Solar Power Converters
Solar Power Converter
The capacitor in renewable energy like solar inverter and wind turbine applications are developing very fast in recent years. The boom of renewable energy generation is continuouly drive demand for capacitor used for power conversion funcations in the solar and wind sgements.
Photovoltaic inverters convert the variable DC voltage generated by solar panels into utility frequency AC voltage, which is then fed back into the commercial transmission system or for off-grid use. Since the inverters are generally used in outdoors. Thus require a long-term reliable operation with easy maintenance.
Flair provide with a complete customized capacitors that is popular used for DC support, snubber and output filtering in Photovoltaic inverters which satisfy with its extremly demanding quality.
