In some parts of the world, being able to take running water from the tap is not a given by any means. Water resources are becoming increasingly scarce, water quality continues to fall. With its solar-powered Actun Opti borehole pump, Wilo has created a stand-alone solution to tackle this challenge.
The Actun Opti is specifically designed to be combined with photovoltaic systems, thereby forming a stand-alone water supply system. The borehole pump guarantees optimised output thanks to its high degree of motor and hydraulic efficiency as well as its dynamic Maximum Power Point Tracking (MPPT) algorithm. “The power that solar panels can provide depends on the sunlight – the potential output in each case is determined by the location, time of day and weather conditions,” explained Roman Zielinski, Product Manager at Wilo. “The integrated microprocessor uses an MPPT algorithm to calculate the ratio between the voltage and electric current intensity in order to determine the maximum possible output. These parameters are then translated to higher pump speeds and therefore an increased supply of water.”
The Wilo-Actun Opti-MS pump can also be monitored remotely via an app. This means that pump operations can be controlled using a smartphone, even at great distances. The high-quality materials used in the submersible pump’s construction also ensure a long service life. All relevant components – such as the pumps’ motor shrouds, impellers and guide vanes – are made entirely from stainless steel.
