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
Inverters are designed to power traditional pumping systems using solar energy.
This way it is possible to convert old systems into renewable energy installations or to use the same AC pumps to create independent, cost-saving and environmentally sustainable water systems.
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.
It can be used with any type of traditional AC pump thereby offering maximum flexibility in several areas of application.
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.
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.
