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

The combination of VASCO Solar 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

VASCO Solar 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.

VASCO Solar 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 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

VASCO Solar 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 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.

Complete pump protection.

VASCO Solar is able to protect the pump against overload and dry running.

Dry running protection is performed by monitoring the motor’s power factor and therefore probes are not required.

VASCO Solar also protects itself against surges and overheating.
