In the application with solar panel, the function MPPT (Maximum Power Point Tracking) maximizes the input power for various conditions of radiation and temperature. When radiation grows, pump increases the rotation speed as well as the water flow . When radiation decreases (presence of clouds or different hours of the day), pumps reduces the speed and thus the water flow but still provide water until the radiation falls below the minimum value to ensure the operation. Installation Wilo-Actun OPTI HS pump can be installed with External control module or without it, so becoming a “plug and pump” system. If no external control module is used, signal cables can be used to control pump ON/OFF the connecting, for example, a float switch All the protections against overload, overvoltage and dry running are integrated into the on board inverter. If the signal cables are connected to the External control module, it is possible to: Control the electric parameters (current, power, voltage). Record and store all the alarms related to the working hours. Connect a pressure or a flow sensor to control the pump performances. Connect a pressure or float switch. Provide an alarm digital output for remote control.
The Wilo-Actun OPTI HS is equipped with a helical rotor that moves within a double helix rubber stator. The rotor is made of AISI 316 stainless steel and coated with a hard chrome surface. During operation, the rotor moves on the rubber surface and it’ s lubricated by the pumped water. The flow rate is directly proportional to pump speed while the pressure supplied is kept almost constant. In this way, unlike a centrifugal pump, the helical rotor pump provides high head even at low rpm, ensuring water on surface even with very low available power or low irradiation. In addition, the helical rotor pumps feature higher hydraulic efficiency than centrifugal pumps of same flow. This saves in the number of PV panels necessary for the application. Permanent magnets motor The Wilo-Actun OPTI HS is equipped with AC permanent magnets motor. The rotor uses Neodymium magnets coated with thin layers of Copper and Nickel, to ensure, in addition to superior magnetic performance, greater reliability and durability. High motor efficiency and high starting torque make pump moving even in low light conditions. The integrated inverter module realizes the conversion from DC energy into useful electrical energy to drive the engine efficiently and, at the same time, adjusts the pump speed in relation to available irradiation, maximizing the power extracted (MPPT). Over-current, over-temperature, lack of water protections are integrated on-board.
