this is correct. but it is unlikely that it will supply a 100 Amp load for one hour. > 2.

The battery bank will have a maximum rated charging current. You should not exceed this. > How many minute/hour will we need (in full sun) to charge an "empty" 24 volt > 200 Ah battery bank with a solar panel that rated as : > + Peak power voltage 35V > + Peak power current 3.15A hehehehe, weeks? this will take a long time, and it is not something that should be attempted. Basically, the task of the battery is to supply energy while the solar panel cannot. All this must be done with the capabilities of the battery. There are different types of battery with different characteristics. Many things should be taken into account in a properly engineered solution, however these rules always apply ; 1. google for a week about it 2. make it twice as big 3. draw it, and place it on your webserver - paste the link everywhere and ask for opinion 4. forget the engineering and buy something and hook it up. all IMO HTH, Steve ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
