New VASCO – VAriable Speed Controller – Solar MP.

The inverter in MP (MultiPower) version can be powered in DC by solar panels or in AC by network or generator to ensure the functioning of the pump at any hour of the day.

This controls the peaks of water demand using AC input to avoid the oversizing of the photovoltaic system.
HMA accessory, used in combination with Solar MP models, manages independently the exchange from a source of energy to another on the basis of several options that can be select by the user:
• irradiance level
• hour of the day
• achievement of the requested daily range
• remote control trough digital command

The inverter for solar pumping applications.

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.

Designed to resist.

The device is built entirely of aluminium to ensure maximum cooling and durability. All other metal parts are made using AISI 304 stainless steel and therefore resistant to corrosion.

Two independent external fans and an internal fan provide perfect cooling. Their operation is adjusted according to actual thermal conditions, thus extending life.

Maximum flexibility.

When using surface pumps, device can be used for an irrigation system drawing water from a nearby water supply, or powering a pool pump at no cost.

When using submersible pumps, it is possible to fill tanks for watering livestock or simply irrigate lawns or crops.

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

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.
