The diagram below shows the working principle of the most basic solar charge and discharge controller. The system consists of a PV module, battery, controller circuit, and load. Switch 1 and Switch 2 are the charging switch and the discharging switch, respectively.
Solar battery discharge curve for a 24V lead acid battery The followings could be observed from the above graph: Range between 80% to 100% yields above rated output voltage, but the voltage drops quickly. The battery could be charged up to 100% if the load requires a voltage boost for a short amount of time.
The batteries have the function of supplying electrical energy to the system at the moment when the photovoltaic panels do not generate the necessary electricity. When the solar panels can generate more electricity than the electrical system demands, all the energy demanded is supplied by the panels, and the excess is used to charge the batteries.
A battery is an electrical component that is designed to store electrical charge (or in other words - electric current) within it. Whenever a load is connected to the battery, it draws current from the battery, resulting in battery discharge. Battery discharge could be understood to be a phenomenon in which the battery gets depleted of its charge.
A solar charge controller is a critical component in a solar power system, responsible for regulating the voltage and current coming from the solar panels to the batteries. Its primary functions are to protect the batteries from overcharging and over-discharging, ensuring their longevity and efficient operation.
The types of solar batteries most used in photovoltaic installations are lead-acid batteries due to the price ratio for available energy. Its efficiency is 85-95%, while Ni-Cad is 65%. Undoubtedly the best batteries would be lithium-ion batteries, the ones used in mobiles.
