A typical solar pumping system is composed of a PV generator array, a pump and a solar pump controller. Based on the design philosophy that it is more efficient to store water rather than electricity, there is no energy storing device such as a storage battery in a typical solar pumping system.
The PV generator, an aggregation of PV modules connected in series and in parallel, absorbs solar irradiation and converts it into electrical energy, providing power for the whole system. The pump controller controls and adjusts the system operation and adjusts the output frequency in real-time according to the variation of sunlight intensity to realize the maximum power point tracking (MPPT). Each LORENTZ pump system consists of a pump end, pump motor and a controller. This modular concept keeps all electronics above ground even for submersible pumps, simplifying servicing and lowering cost of ownership.
