Can any one provide me a circuit for a solar battery charger for a seal lead acid battery of 150Ah. I have two 100w solar panels of 21.8v peak volts each.
I would look into IC's that have a lot of the functionality built into them. In most cases you can get samples of them also. Between Linear technology, TI, Maxim, and freescale you should be able to find some. They have both standalone and controller based IC's that are kind of all in one solutions. They do voltage monitoring, temperature monitoring, and do both normal and trickle charge. Start there and let me know what other questions you have.
