Great sounding product. I'd have to do the math on 2kW continuous and they are not small! They also have to be installed on the DC side and there's nothing said about the charge time.

Seems pretty cheap for a lithium ion battery of that capacity? 10 year warranty. Could be a pretty sweet addition to solar panels on a house!
I wonder what kind of savings you could make by only using off peak rates from your supplier verses the cost of the unit over 10-20 years.... Time to get the calculator out.

Certainly sounds cheap - but!
1. Those are $US for delivery in U.S.A. Add exchange rate conversion, Delivery to Australia, GST, and "Australia Tax", and it may not look as good.
2. This may be even more important. If faced with significant numbers of customers using off peak power only, how long do you expect current price structures to continue? Expect them to change pretty smartly to a fixed connection charge that reflects the real network cost, with power charges close to what they actually pay the generator companies for the power. This will upset your calculator costs. Of course, you can then go completely off grid, but you will need a lot bigger battery set than that, and expect, again, if a lot of people do this, for a "supply available" charge to appear, in the same way that water and sewerage charges apply to even a vacant block in many places.
Of course, if costs get low enough for batteries, it will spell the end of a lot of power networks (who may well install their own local battery banks to keep the nework going long before this), but I expect that will take many years.

Bah, Lockheed Martin will have a compact fusion reactor available within 5-10 years. I'd be saving my banana skins now.

I'm having serious thoughts about this Selectronic Australia Pty Ltd - True Sine Wave Inverters , although I think the battery technology may get there first, that is, before I go ahead with this style of system.

as much as i like the idea. its uneconomical for most households.
Lithium battery costs are dropping around 14% every year. Tesla's giant battery factory comes online in 2017 or thereabouts. This is the coal generators worst nightmare. Not long now.....
Was in a meeting today with a Manager from one of Victorias supply authorities. They know the writing is on the wall and have seen demand drop year on year. They are now getting into the solar market as they see most poles and wires going the way of the dodo within 3 decades.
They are already seeing a massive increase in off grid systems in remote areas. Space for panels and batteries will be a more limiting factor in modern suburbia for the time being. He showed me one system that doesn't even use a backup generator and has run now for over a year. Draw back is that there is 15KW of solar panels - most suburban properties wouldn't have the room to place that many panels in the correct orientation.
I'm sure things will progress nicely in coming years.

whats the cost on 15kW now days?
$10k?
