Nastec 4HS


4HS MultiPower is a submersible pump from the new range of 4HS pumps. The 4HS MP features a built-in inverter. Powered by renewable energy sources, the 4HS MultiPower pumps can be powered by AC or DC with a wide range of operating voltage. 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.

Maximum Power Point Tracking (MPPT) – Always the maximum power available

Based on the variations of solar irradiation and temperature, MPPT 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 irradiation falls below a minimum level necessary to ensure operation.
