Has anyone on FF gone (or know some that has gone) totally off the grid with systems like these?

Living semi-rural, I love having my own water supply and it'd be great to double down and 'cut the cord' being the boss of my own electricity as well!

A couple of weeks ago the t.v news in Melbourne was saying that there will be power increases of up to 40% by June because they have shut down the brown coal power station in Morwell after operating for 60 years.

Why the bloody hell did'nt they convert the station to clean coal technology?

Only other option is Tesla's new 'Powerwall' battery pack for solar systems but I think they're pretty expensive as they're only new at the moment?

I am told by HV engineering specialist that the best maintained infrastructure at the moment is privately owned infrastructure in Tasmania and qld....

Hazelwood was fairly well knackered, I've done work off an on over the last 10 years on the boilers and turbines.

Well I dont know what the hell Victoria is going to do now.....Hazelwood also supplied power to S.A did'nt it?

They had a massive blackout last summer because of overload on a 40% day.

Why are'nt we building LNG power stations.....Surely thats alot cleaner than coal?

s.a gov is going to build there own gas fired power station

Reckon it's got something to do with the $120 Billion + dollars spent on recent LNG extraction processes - Companies want to reduce risk, they sell forward contracts to overseas buyers. So "none is available",To get their returns on any surplus, they now doubling gas prices.
Govco too stupid to do what USA does - i.e. require a licence for export, granted based on things like internal demand..

Really use to be basic stuff - but it takes a long time to create dinosaur farts, not long to sell quickly overseas once extracted though - a one time deal, and it's likely they'll never pay tax on it.

What a mess

Tesla has just released the price for his solar panel roof tiles $21us per sq ft
still need batteries for base load when the sun goes down.

Thats what the Powerwall is!

I'm pretty sure its lithium ion design so no deep cycle lead batteries that only last 5 years.

10-15 years ago we had a Premier who said I'm going to quarantine 10% of the Nth West Shelf gas reserves for WESTERN AUSTRALIANS future.

What happened? The other side screamed that you can't take money away from Gina and the multinationals who are raping the place.
So we have no cheap gas. Who do we blame? The people of WA who voted against it.

We are our own worst enemy...

Now most of our power plants are running on LPG and people are screaming the price of gas is too high. You can't make this stuff up...

It's just like the MRRT that Gillard proposed. Who is paying for the shortfall in tax now? Us...THE PEOPLE! Who happened to rally against it.

There is a calculator somewhere online for the solar tiles. Think it came to $32,000 for 4kw.

Where did you pull 5yrs from. Deep cycles last a minimum of 10 just like lithium. Pros and cons with lithium and deep cycle. Price of lithium is rapidly reducing.

OK, but only because there are only 2 posts in that 3000+ post thread that are older than this thread

Consider it done.

If you want to look at solar storage batteries long term the most economical would be Nickel-Iron.Not a lot dearer than better lead acid,but with a 40-50 year life span compared to 5-10 for either L-A or Lithium

might have to look into this as i dont know much about them

[comagutsa]

so let me get this right
new powerwall 2 is 13kwh for $10,000
Nickel iron cell 1000(ah) 1.2voltage percell at approx $810 AUS x 10 to make 12v = $8100
is 12v the way to go or do you need more ??? i don't know
so 1000 AH x12v = 12000watts which + 12 kwh

(Now that price i got off here http://ironcorebatteries.com.au/page2.php but on another site i got this http://www.offgridbatteries.com.au/n...fe-1-2v-cells/ which is correct ???)

the 2nd one say for 1000ah batteries and 10 of them to equal 12v is only $1611 for 12kwh so which is right??? as that is a huge difference between them
OK JUST DID SOME DIGGING, the 2nd place now says $16110 for 10x 1000ah-1.2v batteries once i put into Shopping Cart, so alot more epensive than the ones off IRONCORE

TassieF100 where did you get they are "Not a lot dearer than better lead acid" a single cell 100ah 1.2v is $161 from off the grid batteries ..1.2v isnt going to do much.. thats close to the price of a deep cell lead acid 105ah 12v battery

A very interesting article, and a company that I think will be competing, and will probably beat, Tesla for the home battery market.

Anyone had any dealings with any f their products? Are they available in Australia yet?

[ford man xf]

Would this actually be possible, wouldn't it really depend on a number of factors like size of home, how many people live there etc.? I wouldn't mind paying the money, after a few years it's paid itself off.

This guy spent more than $10,000 on Tesla's home battery, calculated he'll have a $0 electricity bill

One of the first owners of the new Tesla Powerwall 2 home battery has used a formula to calculate that he will have a $0 electricity bill by using the battery.

The Powerwall 2 is the latest generation battery released March in Australia, which at the time prompted Atlassian's Mike Cannon-Brookes to place a highly publicised bet with Tesla founder Elon Musk to solve South Australia's blackout woes.

Brendan and Josephine Fahey's house, in the northern Melbourne neighbourhood of Coburg, is the first to have the Powerwall 2 system installed in the city. It's understood their case is one of the first deployments globally as well.

Brendan Fahey bought the new 14kWh battery to pair with his existing solar panels after carefully doing the sums to work out he could have a zero power bill.

"I did some calculations with Powerwall 2 by writing a little formula based on my solar production and electricity usage for each day from 1st December 2016. Starting with a 14kWh home battery I subtracted and added on the gains and losses as I went through the six months up until a few weeks ago," he said.

"At no point in my calculations did the 14kWh battery run out. If I had owned Powerwall 2 during that time I would have had no electricity bill."

Also read:Tesla opens Solar Roof orders- here's how much it will cost

The Tesla website indicates a price of $8,750 for a Powerwall 2 and "supporting hardware" plus installation labour costing from $1,150 to $2,900.

There have been criticisms of the overall cost of the Powerwall 2, with SolarQuotes chief Finn Peacock saying in March that Tesla's new battery was already "beaten even before the first deliveries".

"A relatively unknown Australian company, Ampetus Energy, have released a 3kWh 'Super Lithium' battery retailing for $2,300," Peacock told energy industry publication One Step Off The Grid.

"This is available to ship right now and beats Tesla with a cost-per-warranted-kWh of $0.19. This is mainly due to their 15 year warranty, which is also the best in the industry."

Traditionally homeowners used the electricity generated from solar panels in real-time as it was provided or, if excess was harvested, could sell it back to the general grid. But with the feed-in payment rates fluctuating according to market forces and government regulations, and battery technology fast improving, storing the excess energy is starting to become an alternative.

Last September, Business Insider reported a Gold Coast man that installed six 6.4kWh batteries of Tesla's previous Powerwall 1 model to become completely self-sufficient.

The guy's calculations are wrong....

He lives in Melbourne and has only calculated the solar energy generated during the summer / autumn months from 1st Dec 2016. On overcast Melbourne days during winter, the gains are far less. He needs to calculate an entire year to be more accurate.

A friend of mine recently spent $20,000 on a solar panel system including an L.G. battery for his home.

I said to him if he had put the $20,000 into super or an investment compounding at 5% p.a., after 10 years he would have $32,577 before tax.

He currently spends $2,500 p.a. on electricity, so will take him at least 8 years to recover the cost, and that's assuming he has a $0 electricity bill.

The problem with solar battery storage at the present time is the high cost and life span of them. If the batteries of say 12KWh capacity were down to around $3,000 - $4,000, then it would be worth it.

However, I've been told by a solar supplier that the good thing is that in Victoria from 1st July, the feed in tariff is increasing to 11 cents per kilowatt for new installations... So anyone considering going solar should hold off.

[lgpking22]

In s.a its going the opposite i was reading there going to start limiting single phase installs to a maximum of 5kws no exceptions soon will be interesting to see if it becomes truth.

[FoxtrotGolfXray 5.0]

For those of you in the know, can you please tell me about one thing I'm interested in with respect to a battery-backed home solar system?

With just a roof-top solar system, anti-islanding requirements automatically isolates the inverter from the main switchboard in the event that power from the grid is lost. This is required to ensure the grid supply line is dead when isolations at either end of the supply line are activated so that workers are not at risk. In effect, this means that, when there is a power outage on the grid, your solar system is useless to you.

How is this managed if I were to add a battery back-up? I assume that there is an automatic switch of some type installed to allow the solar system to still function, ie supply the house, during a grid power outage.

And, if this can be done with a battery back-up, why can't it be done with a roof-top system without battery storage?

All of the above assumes the house is fed from two supplies; the roof-top solar and the grid.

I think I must be missing something.

New or old system it doesn't matter when it was installed, the rebate is increasing for everyone in Victoria.

Excluding people who already have a bigger buy back.

Just found out that apparently we have just gone up to 10.102c here in regional Qld.

I'll have to be careful to not splurge out with the newfound wealth!
