It is fitted with the advanced MG Flex variable frequency driven motor that offers the following features:-\u003cbr\u003e\u003cbr\u003e• Runs at varying speeds depending upon the energy input available.\u003cbr\u003e• Can be used for DC or AC power supply and can therefore be connected to either PV solar modules, a standby AC generator or mains power supply as required.\u003cbr\u003e• Utilises Maximum Power Point Tracking (MPPT) technology that continuously optimises speed according to input power.\u003cbr\u003e• Built in protection for under and over voltage and system overload. No additional protection is therefore required.\u003cbr\u003e• One set of terminals included for either high or low level control functions.\u003cbr\u003eThree models are available, all powered by the same 1250W motor providing a selection of head and flow outputs depending on application. System sizing is easy using the Grundfos WinCAPS PC based sizing tool that optimises system design given the installation location, total head and water output required.\u003cbr\u003e\u003cbr\u003eMaterials of construction are stainless steel for the hydraulic parts and cast iron for the pump head and base.\u003cbr\u003e\u003cbr\u003eThe Grundfos CR Flex renewable energy pumping system is efficient, reliable and cost effective and is the ideal solution for all off-grid water pumping applications.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eMOTOR\u003c\/strong\u003e\u003cbr\u003eThe pump is connected to an MG Flex 2 pole variable frequency drive (VFD) induction motor. The VFD controller is attached to the motor and can accommodate a wide voltage range. It also offers over and under voltage, overload and over temperature protection.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePower Input:\u003c\/strong\u003e 880W \u003cstrong\u003eMax Current:\u003c\/strong\u003e 4.6A \u003cstrong\u003e Voltage:\u003c\/strong\u003e 30 - 300VDC\u003cbr\u003e90-240V AC 50\/60Hz\u003cbr\u003e\u003cstrong\u003eCONTROL UNITS\u003c\/strong\u003e\u003cbr\u003eOptions of the IO50 manual solar powered unit and the IO101 solar\/generator flex unit are available.
