Nastec VASCO Solar (VAriable Speed COntroller) inverters are designed to power traditional pumping systems using solar energy. Available in MP (MultiPower), the MP 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.

Maximum Power Point Tracking (MPPT) – Always the maximum power available
Based on the variations of solar irradiation and temperature, MPPT 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 irradiation falls below a minimum level necessary to ensure operation.
