VSP systems are created to meet the widest variety of pumping applications using solar energy.

The combination of VASCO Solar – VAriable Speed COntroller inverters with the complete range of stainless steel submersible pumps ranging from 4” to 10” offers a solution of superior quality, unique in its reliability, variety and performance.

Whatever the demand for water, there is always a VSP system that can satisfy it.

VASCO Solar – VAriable Speed COntroller

It is able to convert DC voltage coming from solar panels into AC voltage for powering any pump driven by a three-phase motor.

Pump speed is constantly adapted to available solar irradiation thus maximising the amount of pumped water and making possible operation even in conditions of low sunlight.

It also offers complete pump protection against surges, overloads and dry running.

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.

Monitoring parameters

VASCO Solar – VAriable Speed COntroller is equipped with a backlit alphanumeric display and is designed to monitor key electrical parameters like input voltage, power, current and motor power factor.

It is also possible to connect a pressure or flow sensor to monitor performance levels.

In the diagnosis menu are recorded inverter and motor hours, operation statistics, and the last eight alarms occurred. The programming menus are password-protected to prevent unwanted tampering.

Advanced connectivity

The device can be connected to:

An alarm
A motor run/stop signal
A pressure sensor or a flow sensor for monitoring
Up to 4 digital inputs for pump start and stop (float switch, level sensors, etc.)
Modbus RTU

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
