    Some friends and I were lucky to find a military industrial source of 40-50amp cells in China who sold us extra cells they had left over from orders and we got them for a very good price when our dollar was high. One friends work place imports auto parts from China and she was able to find a cheap source through her contacts. Was a bit worried they may be dud or second hand like my first cells, but had some for more than two years and they have performed excellently. They would be a lot dearer now as our dollar has dropped so much, but we took advantage of the price when our dollar was over $1 USD, whilst others dithered and missed out.

    Hey spook,

    You have been asked some direct questions and what has the forum in return - froth and bubble.

    We all know that Lithium cells are vastly different from lead acid but that is all you have been telling us.

    Froth and bubble, hilarious, what else is there to tell other than how they work and how to treat them. I'm no technical person and don't have clue about the internal workings other than what is needed to understand and use them safely.

    I'm sure there are many who would be able to discuss the physics of lithium chemistries, but not me. If all I've posted here is froth and bubble, won't waste my time and have better things to do with my life.

    If you did know lifepo4 were vastly different to lead acid and way superior, you'd have them already. Knowledge is power if you use it properly, why would anyone continue using expensive wasteful and useless energy storage, when there is 21st century storage available far superior in every way and especially economically.

    Certainly not going to reveal our sources, it may jepordise the job of someone and when we want more, may effect our buying power. Getting our sources took a long time and lots of research, it was only when we discovered we had someone who already had contacts in china that things went forward.

    Wasn't going to say the price as you probably wouldn't believe me, but if you must know, we paid US$29 for 40amp cells and US$28 for 45amp cells. Our dollar was over US$1, so we took advantage of that brief situation, it's called good business sense. The 45amp were cheaper because we bought what they had in stock and were lucky to have an insider, so when they became available, we grabbed them.

    By the time it gets to Aus it will probably be nearer $5,000 which will buy the proverbial shed load of electricity at the normal rates.

    Note also:

    "The benefit then to those without solar panels is load shifting. This means that the battery can charge itself during the night when electricity is cheaper and then discharge itself during the day when it would usually cost more. This could potentially halve your electricity bill in some states."

    There will be somewhere between nil and zero chance that your electricity supplier will allow connection to the controlled load - read electric hot water - meter.

    There really have been some sunny days of late and in mid November I had one day where I generated 50 kWh for a single day. I cant recall ever having a 50, but I dont check very often. Just looking now, there have been plenty in the 40-50 a day range.

    Looking at November, I had 20 days where I generated more than 25 kWh's and 19 days of the same for this month.

    It looks like I am down a bit this year, last December I generated 926 for the month of December, while I am up to only 862 so far, though with 4 good days to go I may end up with the same.

    The November comparison was interesting. Last year I generated a whopping 990 kWh's for November, this year it was 893.

    So far this year, I have generated 7,707 kWh's and should add at least another 100 to that in the next 4 days.

    Anybody post a years month by month data for Tassie?

    EDIT: Or better still day by day data.

    EDIT 2: admin, I thought you were Powershop?

    EDIT 3: Following admin's advice in the post below this - North Tassie say Burnie.

    I am with PowerShop. United Energy are a Victorian Electricity wholesaler, not retailer. UE supply to a designated part of Victoria, you can pick your own retailer. Any customer that has power that comes from UE can have a free login to see their power use (and generation if you have solar). We have it down to a fine art in Vic Smart meters make life very easy to monitor your use, and probably the biggest savings you can make are by simply keeping an eye on what you use.

    Also your Tassie request probably needs to be clarified....there is a big difference between North and South.

    Allover, yes, will always be keeping an eye on battery prices, there is a lot of discussion about the Tesla Powerwall at the moment. I am looking forward to a battery bank and leaving everything on day and night

    Anyone want $75 of free electricity for switching to PowerShop ? (no contract, cancel switch at anytime)

    From an article in the Age, 21 August, 2015, "and home battery vendors, such as Sunverge and Octillion, are quickly setting up shop in Australia."

    EDIT: Meaning that there are other options. Tesla just gets the headlines!

    spook's comment regarding LiFePO4 as the only way to go has to be heeded.

    You can also buy beta and then find out VHS is the winning format.

    Discussion between LiFePO4 and Tesla Powerwall is about 90/10 is Tesla's favour at the moment and unless something drastic happens, I cant see it changing. But thats something for another thread (I think we already have one)

    I just looked at my inverters (which I don't usually look at because my son has piled a heap of crap in front of them) and noticed that they have both now generated over 25,000 kwh's each, so total for the system was about 50,300 or something.

    So still humming along quite well, first day was 26 Feb 2014, so better than 10,000 a year


    Edited Huge typo - It's 50,300 total , not 25,300 !

    its nice looking at the output, my 2 have been running since
    22 November and am more than happy

    6.3Kw setup = 1592
    1.5Kw setup = 378

    I was very interested in watching outputs, I lost interest fairly quickly after it was installed. Having said that, United Energy are my distributor and as I am in Victoria, every one has a smart meter so I can login to United's "Energy Easy" portal and see what I use or generate whenever I want. Its updated quite quickly being linked to smart meters.

    Of Course newer inverters have better features than mine, wifi was a top line option back then.

    Guiseppe, just for the record this was former member z80 who is indeed a technical person, so he was not being truthful to you with what he did and didnt know on the subject.

    I thought that is what you meant.

    So at an average price of 33cents per KWh, that is $16,600!

    Do i have this right?
    Geez, that is fantastic for something that is only working in premium daylight hours when the sun is out!

    Just checked my meter and i have exported 34,000 KWh since install - at 44c feed in tarriff that's almost $15,000 right there - me thinks that the system has paid for itself

    Doesn't matter admin. I have made my own decisions about how to make money to pay for my electricity use.

    No I am not going to explain on the forum or by any other means as it could be construed as financial advice.
