It guarantees: ■ Energy saving thanks to photovoltaic energy supply and variable-speed operation. ■ Quick return on investment. ■ Lengthening of system life and greater system reliability. ■ Quick and simplified installation thanks to the electronics integrated into the motor and smartphone control. ■ Extremely low noise operation. ■ Installation in humid and dusty environments thanks to IP55 (NEMA 4) protection rating. hydraulic part with rapid extraction inlet pre-filter. Carbon-ceramic mechanical seal. Pump body, impeller and diffuser in reinforced technopolymer. Transparent...

SUND is powered by solar panels or, if necessary, by mains supply. In this way, the pump’s operation is guaranteed at any time of day. on multiple logics that the user can select: It is also possible to meet demand peaks through mains power in order to avoid the over-dimensioning of the photovoltaic system. radiation level When installed, the HMA accessory automatically manages the switch from one source of energy to the other based remote control via digital input. time of day achievement of the daily flow requirement Integrated inverter attached to the motor, exclusively in aluminium, and...

MPPT: always the maximum power available 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. 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.

Built-in protections against: ■ Overvoltage and undervoltage. ■ Overcurrent and no load. ■ Dry running. ■ Overtemperature. EMC compatibility for residential environment: ■ Integrated PFC (P.F. 1) to meet EN61000-3-2 ■ Integrated input filter for Category C1 (EN61800-3), Class B (EN55011)
