About SHANGHAI SURPASS SUN ELECTRIC CO.,LTD.
SHANGHAI SURPASS SUN ELECTRIC CO.,LTD. specializes in the research, development, manufacture, and supply of power electronics and energy solutions. Its core offerings include PV inverters and chargers, active harmonic filters and power factor correction equipment, capacitor banks, and liquid resistor soft starters and speed regulators for large electric motors, together with high- and low-voltage switchgear.
In harmonic filtering, the company pioneered active harmonic filter development in China, integrating FFT with Instant Power Theory to support advanced power quality management. For high-tension motor starting, it introduced liquid resistance soft starters in 1999 and has delivered large-scale solutions up to 30MW.
For solar applications, the company provides three-phase on-grid PV inverters that combine inverter design with active harmonic filter technology, achieving very low total harmonic distortion in current (THDi) performance. It also undertakes solar projects on an EPC basis, applying system MPPT technology designed to enhance solar plant efficiency. A total of 80MW of EPC solar projects have been running reliably since September 2010.
