Ampere Hour (Ah)
The capacity of the battery is represented in Ah. It is the amount of current a battery can give during one hour of charge / discharge cycle. High capacity batteries (100 Ah, 150 Ah) are used to power inverters to get sufficient backup time. The formula to select the battery power (Ah) is Load in watts / Voltage of battery x Backup hour.
For example if you wants to run 400 watts load on 12 volt battery for 3 hours, then the capacity of the battery should be minimum 100 Ah.
Ah = 400 / 12 x 3 = 100 Ah. If the load increases (within the capacity of the inverter), backup time reduces.

How many hours to charge a 12v 150 ah battery with 150 watt solar panel?
To charge a 12V 150Ah battery using a 150W solar panel, you first need to calculate the total watt-hours required to fully charge the battery. A 150Ah battery at 12V has a total energy capacity of 1,800 watt-hours (12V x 150Ah). With a 150W solar panel under ideal conditions, it can produce about 150 watt-hours per hour. Therefore, it would take approximately 12 hours of optimal sunlight to fully charge the battery, assuming no losses and full efficiency. However, real-world conditions may extend this time due to inefficiencies, shading, and weather factors.
