Leading a dynamic team that commercializes breakthrough technologies for super-fast EV chargers market

Advised on technology development and vision.

SunTech Drive technology was recently acquired by Premier Manufacturing and UPC Capital, and we are now known as ENFusion. Our commitment to building innovative, load-facing solutions remains the same. Our patented technology provides the capability to seamlessly blend AC and DC sources with a universal, “smart” controller that can stabilize the grid, enable off-grid operations, and manage local storage. Newest products include: Blender 20K, a high-voltage power controller that turns standard industrial motor loads into smart flexible loads resulting in a 50% electricity reduction in both energy and power demand, and the ENStratus Comm, which enables customers to remotely access ENFusion power controller devices and have full control of their operation from the ENStratus web app.www.ENFusionEnergy.com.

Co-founded SunTech drive to develop efficient, versatile, and patented power electronics for solar controllers and drives that directly power inexpensive AC motor loads for off-grid solar water pumping -- improving both efficiency and cost compared to DC motor solutions. Notable applications: solar water and air pumping, off-grid AC motors powered off of solar, and solar power blending for grid stabilization.
