Solar Battery

Solar batteries are used to store solar energy (solar electricity) and discharge power as and when needed. Rechargeable solar batteries are used in off-grid PV systems to store excess electricity. Some solar battery banks use wet cells, while others use sealed or gel cell batteries. Each of these batteries have different temperature, mounting, and ventilation requirements.

NiMH batteries are preferred and most common when it comes to solar energy because they are better than standard NiCAD batteries in terms of charging and release cycles.

How Solar Battery Works

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

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.
