The most important features when selecting a battery or solar kit

1. Capacity
The capacity is the current intensity in ampere (a). When the battery is fully charged, it can be obtained from the full discharge of the battery.

2. Charging efficiency
Charging efficiency is the ratio of the energy used to fill the battery to the actual stored energy. Therefore, the closer to 100% the better.

3. Self-discharge
Self-discharge is a process in which the battery tends to discharge when not in use.

4. Discharge depth
Discharge depth is the energy (%) obtained during full load discharge.

Batteries are very important in off-grid systems

In an off-grid solar system, when the solar modules produce more electricity than is required by the electricity system, the excess energy is used to charge the batteries. The electricity stored in the batteries is then made available to customers when the electricity supply is low, ensuring that there is always enough power available to avoid power shortages.


Working principle

The battery converts the electrical energy received from the photovoltaic module into chemical energy. This conversion is carried out by the reaction that takes place when two different materials (such as the materials of the positive plate and the negative plate) are immersed in the electrolyte. The electrolyte is a solution of sulfuric acid and water. Once a circuit is connected between the positive and negative poles, current flows from the battery. As the battery discharges, the composition of lead in the plates becomes more similar. At this time, the acid concentration decreases and the voltage between terminals decreases. The ability to experience a constant charge and discharge process is called the cycle resistance of the battery.
