The average speed of a pump driven by an inverter is inevitably lower than a comparable fixed speed pump. This reduces component wear such as bearings, bushings, seals, etc.
The inverter also starts and stops the pump gently, reducing the mechanical stress on the shaft and impellers and avoiding water hammer. Hardware and software protections prevent any damage to the pump and the system.
At lower speeds, the system will also generate less noise.

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:
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.
