ALR> Bye for now, ALR> Angel Great. Here's the first: I will [hopefully] be building a house in the next year or two that will ultimately serve for retirement and, in the intervening period, holiday use. It's off the grid and remote from where I am now. If everything works out it will ahve a mix of hydro, solar and wind power systems. For now I may only be able to visit 3 or 4 times per year and I don't believe it would be prudent to leave an active system(s) charging unattended batteries for that period. That would be a recipe for disaster. But - My understanding of battery systems is that to permit them to discharge during an unoccupied period will rapidy destroy their capacity. How might that best be handled? - Is it as big a problem as it's made out to be? (By all the material I have seen it surely is). - I'm thinking about a very small solar subsystem on top of the turbine that would be only powerful enough to prevent the batteries from self-discharging over long periods (5 watts?) but not so powerful as to represent a problem if there is a failure when no one is around. Comments? Other tactics? -- Cheers, brian mailto:[EMAIL PROTECTED] ------------------------ Yahoo! Groups Sponsor --------------------~--> Make a clean sweep of pop-up ads. Yahoo! Companion Toolbar.
