i am working on a project that runs on solar energy. i need it to operate 24*7. so used a battery to charge parllely. sometimes charging and discharging of battery need to happen simultaneously is there any possibilities????
I have about 20 square feet of solar panels. The load on the batteries is not a secret. It is amateur radio and some lighting. The reason for the large capacity of batteries is if bad weather prevents the panels from charging the batteries I have over a week of normal use. All batteries have a AH rating and a normal discharge. Lead acid has the discharge rate of 20 hours, so I could get 11.25 amps for 20 hours. My lights are used about 6 hours a day and use about 3A. The amateur radio gear uses about 10A and is only used a about 2 hours a week. I use golf cart batteries 2ea 6V in series. I have had the solar panels about 15 years and I am on my 3 set of batteries. The batteries have been lasting about 6 years.k7elp60 - 20A? How many sq ft is the solar array. And if it's not secret, what is the application for radios and lights that take 225 A-h for backup?
Just curious.

Mr. Chips is correct, the batteries do not charge and discharge at the sameNo, the battery is not charging and discharging at the same time.
It can do one or the other but not both.
When the charging system (solar panel or alternator) is below the voltage of the battery, the battery is going to supply the needed current. It can supplement the charge coming from the charging system. The battery is not being charged. It is being discharged.
When the voltage of the charging system exceeds the battery voltage, the battery is being charged. The battery supplies no current to the load.
If u want the battery charge at limit volt u can use ic 555i am working on a project that runs on solar energy. i need it to operate 24*7. so used a battery to charge parllely. sometimes charging and discharging of battery need to happen simultaneously is there any possibilities????
