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.
It is also possible to meet demand peaks through mains power in order to avoid the over-dimensioning of the photovoltaic system.

When installed, the HMA accessory automatically manages the switch from one source of energy to the other based on multiple logics that the user can select:

• radiation level
• time of day
• achievement of the daily flow requirement
• remote control via digital input
