6 FAQs about [Solar energy storage water pump with ultra-long battery life]
What is a solar photovoltaic-fed water pump?
This work deals with the development of an efficient and reliable solar photovoltaic-fed water pump with a battery energy storage (BES). This system ensures a continuous and rated supply of water in all working conditions. A new control logic for BES is developed, which significantly improves the overall response of the system.
Why should a solar water pump have a back-up battery?
The back-up battery together with the grid supply will contribute to the uninterruptable power supply of the standalone solar water pump. The provision to feed the solar power back into the grid can offer an additional benefit to the consumers: to earn revenue.
Are solar-powered water pumps efficient?
Therefore, solar-powered water pumps are the most efficient way to utilise the available abundant solar power [ 4, 5 ]. Innumerable research has been carried out to develop an efficient solar-powered water pumping system (SPWPS) using various electric motor drives [ 4 - 7 ].
Why do solar water pumps need a reluctance motor drive?
Therefore, a reduced-component four-phase switched reluctance motor drive is utilized to improve the cost-effectiveness and reliability of the system. The back-up battery together with the grid supply will contribute to the uninterruptable power supply of the standalone solar water pump.
Which machine is used in solar water pumping system?
The most frequently encountered machine used in solar water pumping systems is the three phase induction motor. Its popularity is due to its capability of producing high power, simple design, and it's easy to maintain . The DC/AC voltage source inverter (VSI) is employed to feed the motor driving the centrifugal pump .
Can a solar PV array charge a battery without pumping?
Since the PV power optimisation is achieved through the motor control, there is no such MPPT control present when solar PV array is used to charge the battery, and pumping is not required. Besides, the uncontrolled charging/discharging of the battery is also one of the major limitations of suggested system.
