Solar Combo Functionality

To maximize the efficiency and reliability of a solar pumping system, instead of using a single high-power pump, it is possible to divide it into two or more pumps in parallel, each controlled by variable-speed inverters and powered by the same photovoltaic system. When the system consists of a single pump, in conditions of low irradiance, the pump is often stopped as the photovoltaic power is not sufficient to ensure its operation.

Conversely, when the system is divided into multiple lower-power pumps, even in conditions of low irradiance, at least one or more pumps continue to operate, providing water. This results in a significant increase in the overall efficiency of the system.

In addition, the following are ensured:

• Greater system reliability, as if one pump or inverter were to malfunction, the other pumps can continue to operate.
• Uniform wear of the pumps thanks to the alternating operation managed by the inverters in the group.
