A Valve Regulated Lead Acid (VRLA) battery is a rechargeable, sealed lead-acid battery. It uses a small amount of electrolyte, which can be gel or absorbed in. These batteries store excess power generated from renewable sources such as solar panels and wind turbines. They serve as a buffer, ensuring a steady supply of electricity when
This type of battery is suitable for solar applications because of its long life and maintenance-free features. VRLA batteries are designed to be spill-proof, and they automatically vent the gases produced by a chemical reaction within the battery. They do not need to be refilled with water like a flooded cell battery.
Sizing batteries for hybrid or grid-connected PV systems is beyond the scope of this recommended practice. Installation, maintenance, safety, testing procedures, and consideration of battery types other than lead-acid are beyond the scope of this recommended practice.
Recommended practices for the remainder of the electrical systems associated with PV installations are also beyond the scope of this recommended practice. Scope: This recommended practice describes a method for sizing both vented and valve-regulated lead-acid batteries in stand-alone PV systems.
The requirements for batteries in PV systems in such locations are: long cycle life; wide operating temperature range; low self-discharge rate; good sealing to prevent the escape of water vapor and acid from the battery; resistance to earthquakes with intensity up to 7 on the Mercalli scale. Fig. 4. Diagram of stand-alone PV system. Fig. 5.
The batteries are discharged every day for about 5 h and supply average electrical power of 23.9 kWh every day; the DOD of the VRLA batteries is about 5%. From the curves in Fig. 17 we can see that, in the later part of the period, the electricity supplied by the batteries increased slightly. The DOD of the batteries increased a little too.
