If I want to choose a battery for my solar panel which is required to run a load of 5 kWh/day. Then I will be needing a battery with a rating of above 23 ampere hours since 5 kWh/220 V (since 220 V we get from grid in Pakistan) is equal to 23 ampere hours.
- I want to ask if a battery is of 23 A and it runs for an hour VS a 1 ampere battery which runs for 23 hours. Will they be both accurate as a battery backup for solar panel? Because they both makes 23 Ah
- And if yes, then I wonder how this 1 ampere battery will provide current to my household? My appliances won't run, will they?
- If no, then why do we even calculate ampere hours when they are of no use?
