Solar Batteries are used to store solar energy and discharge power as and when needed. Rechargeable solar batteries are used in off-grid PV systems to store excess electricity. Some solar batteries banks use wet cells, while others use sealed or gel cell batteries.

The home solar system generates DC electricity. This DC electricity is converter to AC electricity by using Charge Controller and Solar Inverter. The battery stores this AC electricity to be used at night or when there is no sun light.

Battery backup time depends upon Ampere Hour (Ah). Higher the Ah, more will be backup time. For Example, 200 Ah battery will give backup of around 4 to 5 Hours if 400 Watt Power is Consumed. This means that we can use electrical appliances like 3-4 Led light, 2-3 ceiling fans, 1 Led TV and charge our mobile phone and laptop for 4-5 hours from the battery backup.

To figure the amount of energy needed to be stored in a battery bank, it is important to know how many days that stored energy can be relied upon to satisfy the consumer’s particular needs.

Cold has a negative effect on battery performance. Temperature must be considered when sizing up the battery bank if the bank is located in a cold, or particularly hot, location. The colder the temperature, the larger the battery capacity needed. Notably hot locations will affect battery lifespan.

Depth of discharge (DoD) refers to the level a battery is discharged before recharging. DoD has a significant effect on battery efficiency and lifespan. In most cases, particularly with lead-acid batteries, a DoD of 50 percent is a good starting estimate. DoD for other battery types may vary considerably.
