Lengthening of system life and greater system reliability.

The average speed of a pump driven by an inverter is inevitably lower than a comparable fixed speed pump. This reduces component wear such as bearings, bushings, seals, etc.

The inverter also starts and stops the pump gently, reducing the mechanical stress on the shaft and impellers and avoiding water hammer. Hardware and software protections prevent any damage to the pump and the system.
At lower speeds, the system will also generate less noise.

SUND is powered by solar panels or, if necessary, by mains supply

In this way, the pump’s operation is guaranteed at any time of day.
It is also possible to meet demand peaks through mains power in order to avoid the over-dimensioning of the photovoltaic system.

When installed, the HMA accessory automatically manages the switch from one source of energy to the other based on multiple logics that the user can select:

  • radiation level
  • time of day
  • achievement of the daily flow requirement
  • remote control via digital input

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.

Unmatched user experience

Thanks to Nastec NOW app it is possible to communicate with all Nastec SMART Bluetooth® devices in order to:

  • Monitor multiple operating parameters simultaneously on the wide, high definition, coloured screen of your smartphone or tablet.
  • Get energy consumption statistics and check the alarm log.
  • Develop programs, save them in the archive, copy them to other devices and share them among multiple users.
  • Create reports with the possibility of adding notes and images, and email or store them in the digital archive.
  • Remotely control a Nastec device via Wi-Fi or GSM by tethering to a nearby smartphone.
  • Promote your work on the Nastec.eu website by sending photos from your smartphone, thanks to the MY WORX section of the new version 2.3
