The ultimate tool for sizing any solar
pumping system
4HS MultiPower pumps can be powered by AC or DC with a wide range of operating voltage (90 – 265 VAC / 90 – 400 VDC). This means that 4HS MP pumps can be connected to solar panels, batteries, wind turbine and a diesel generator.
A special software algorithm allows for adjusting the hydraulic performance to each source and to the available power while maximising the amount of water pumped.
The built-in electronics inside the motor avoid the use of shielded cables and output filters, and it is the ideal solution for any application in remote locations without surveillance and climatically adverse.
In fact, in the traditional solutions, the solar inverter is placed above ground and, being exposed to the weather, could suffer of:
The built-in electronics are directly cooled by the water flow; the operating temperature of the electronic components is so low as to ensure considerably longer life than a surface inverter affected by high temperatures, humidity, dust and sunlight.
If the CM MultiPower control module is not used, signal cables can be used to control pump start and stop, connecting a float switch, for example. All the protections against overload, surges and dry running are integrated into the on-board inverter.
If the signal cables are connected to the CM MultiPower control module, it is possible to:
If solar energy is absent or insufficient, it is possible to power the pump with an auxiliary genset to achieve the desired pump performance.
An AC/DC selector is used to change the power source.
Protection against overload, surges and dry running are integrated into the pump’s electronic circuit.
Electronic protection against dry running avoids the use of probes.
Based on the varying conditions of solar irradiation and temperature, MPPT (Maximum Power Point Tracking) maximises the electrical power drawn from the panels and therefore the amount of water pumped.
The greater the solar irradiation the faster the pump’s rotation speed, and consequently water flow increases.
When solar irradiation decreases (due to clouds or the different times of day), the pump reduces frequency and therefore the flow, but it continues to provide water until the irradation falls below a minimum level necessary to ensure operation.
4HS “H” pumps are equipped with a helical rotor that moves within a double-helix rubber stator.
The rotor is made of AISI 304 stainless steel and coated with a hard chrome surface.
During operation, the rotor moves on the rubber surface and is lubricated by the pumped water.
The flow rate is directly proportional to the 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 solar irradiation.
In addition, the helical rotor pumps feature higher hydraulic efficiency than centrifugal pumps having the same flow. This saves in the number of solar panels necessary for the application.
4HS MP pumps are equipped with a permanent magnet motor.
The rotor uses Neodymium magnets coated with thin layers of copper and nickel to ensure greater reliability and durability in addition to superior magnetic performance.
High motor efficiency and starting torque make it possible for the pump to run even in
low-light conditions.
The integrated inverter module converts DC energy into useful electrical energy to drive the motor efficiently and, at the same time, adjusts the pump speed according to the available irradiation, maximising the power extracted (MPPT).
Overload, overheating, dry-run protections are integrated on board.
