4HS MultiPower Overview

4HS MultiPower pumps powered by renewable energy sources, is a new range from 4HS pumps with built-in inverter

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.

All the advantages of built-in electronics.

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.

Traditionally the solar inverter is placed above ground and, being exposed to the weather, could suffer from:

  • Overheating
  • Water infiltration
  • Thermal shock
  • Damage by animals or people

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.

4HS MultiPower pump can be installed with CM MultiPower control module or without it, thus becoming a plug & pump system

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:

  • 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 monitor the pump’s performance.
  • Connect a pressure or float switch.
  • Provide an alarm digital output for remote control.

MPPT: always the maximum power available.

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.
