VSP-Solar-pumps-with-VSolar.png

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.

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

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.​

Complete pump protection.

 

The device 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.
The device also protects itself against surges and overheating.
