Commercial pool operators not only need to operate their pumps for longer or continuous duty cycles, they typically have water features such as fountains or waterfalls that require a constant flow rate regardless of the cloud cover. SunTech’s power blending functionality allows for these features to operate consistently as clouds pass by or as day turns to night. During the passage of a cloud when the solar irradiance level may drop from 100% to say 85%, the system seamlessly “blends” power from the solar array and the power grid. This allows for the maximum offloading of energy cost to solar without sacrificing any performance. For commercial operators this has the added benefit of being able to show off their green eco-friendly credentials to customers with visible solar panels and signage and even a real-time display showing the offloading of the pool pump.
