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.
Built-in protections against:
- Overvoltage and undervoltage.
- Overcurrent and no load.
- Dry running.
- Overtemperature.
EMC compatibility for residential environment:
- Integrated PFC (P.F. 1) to meet EN61000-3-2
- Integrated input filter for Category C1 (EN61800-3), Class B (EN55011)
Unmatched user experience.
Thanks to Nastec NOW App it’s possible to communicate with all Nastec devices Bluetooth® SMART in order to:
- Monitor multiple operating parameters simultaneously on the wide, high definition, coloured screen of your smartphone or tablet.
- Get statistics of energy consumption and check alarms history.
- Make programs, save them in the archive, copy them to other devices and share them among multiple users.
- Perform reports with the possibility to insert notes, images and email them or keep them into the digital archive.
- Remotely control, via wi-fi or GSM, a Nastec device, using a smartphone nearby as a modem, through the free Nastec REMO service and connecting to remo.nastec.eu
- Promote your work on the nastec.eu website by sending photos from your smartphone, thanks to the MY WORKS section
