It's hard to challenge the authority of a computerised navigator! ;-) We generally don't use it for just that reason (and that it's fun & good practice to read maps)<br /><br />I have no idea about Lithium peaks. Research needed! ;-) For a stationary application I'd be inclined to use Lead Acid or (as you've previously suggested) Nickel iron. Lithium has better round trip efficiency, and better discharge performance, but it's that old story of hidden externalities again ;-). I'd probably plump for Nickel Iron with a few extra PV panels for an off grid system.<br /><br />But first I want to experiment with smart controls on household loads. Our FiT ends next year and I want to be ready with this (before experimenting with storage).<br /><br />Cheers, AngusAngus Wallacehttps://www.blogger.com/profile/01518875828382696708noreply@blogger.comtag:blogger.com,1999:blog-7762293635463803805.post-29478351781259725492015-10-13T04:07:29.620-07:002015-10-13T04:07:29.620-07:00Hi Angus,

Hey, the Lithium battery thing is an interesting issue, because I read over at the ADR that we may well have reached or are beyond Peak Lithium - I'm no expert in such matters though. The off grid people swear by them, but I make do with old school Lead-Acid batteries.<br /><br />Yeah, it all really depends on where you live in Australia and honestly the train and tram networks are pretty good. I can get to Melbourne by train (130km/h they travel at) faster than a car can and I don't have to worry about where to park the car either. Adelaide may be a bit different on that front. Mind you, most of the original lines were laid out in the 1890's - paid for by the many decades of gold rush - and that is a topic that people don't seem to want to consider.<br /><br />We'll have to agree to disagree about GPS - honestly the number of people that get lost traveling here and following the GPS is a truly embarrassing number.<br /><br />Cheers<br /><br />ChrisFernglade Farmhttps://www.blogger.com/profile/06950962122594709186noreply@blogger.com
