been involved with this the last 3 years and we have started bringing solutions out...

South Australia is a big market for us the last 6 months

Been looking to take the house off grid. Looking for solutions.

Thing holding me back is I have a 4kw Solar System and have a 50c solar feed in Tarif which I will lose if I add to the system and add batteries. I installed a while ago and got my money back and then some.

So I’m in a catch 22 because if I add batteries I go to wholesale if I add battery storage.

the future is battery storage...it allows building a dwelling anywhere and living off grid...for inner city not sure how it will work in the future...the current infrastructure, cables, poles, etc, while expensive to maintain is here to stay...

What you need is a full blown photo-voltaic system... what Boomers is offering is power to Doomsday Preppers. :)

you are fucking nutter...what fucking doomsday?...we are not anyway near turkey and greece... :lol:

it has 240VAC outputs...i can power a 50W globe and 50" TV for about 5 hrs...as well as my phones during a power failure which i get in my area 5 times a year with the trees around...

Sth Australia power failures are a regular occurrence...hence why is our biggest market so far...

I've already got a PV System and generate power from it and export excess power to the grid which my retailer pays me for at 50c a Kw.

What I want to do is add to my PV, and also add battery storage so I can store my own power and use it and not import or use ANY power from the grid at night.

So basically, be connected to the grid but not need the grid at all. In Australia, many houses are starting to do this.

That's what I am looking at.

1) add PV output, and
2) add battery storage (for example a TESLA Battery that can store a good amount of power for my needs and is charged by the PV system).

The draw back is losing my FIT rate.

This for a house that is very inner city.

the reason I want to do it is because the power companies piss me off and I don't like being reliant on them.

I had an off grid PV system at my orchard. 2 panels outputting 5 Amps 20 Volts, a Trojan Deep Cycle battery 130 AH, a special charger, and a 2 KW AC converter.
Trojian (made in USA) was supposed to be the best at the time. Cost me about 300 Euros. After 3 years the battery failed.
At anything beyond 800W both the Converter and the battery would bend on their knees.
And suddenly on the 5th year the PV panels started outputting less and less power until they died completely.
I think the whole thing cost me about 900 Euros. At the time the Electricity Authority wanted 2500 Euros to supply me.
When everything broke the price went down to about half so what better choice did I have? I connected to the grid.

Imo those PV systems that charge batteries don't worth it.
You need to change batteries every 3-4 years, and they are really expensive.

You would need at least 4 huge batteries and a huge converter to just run a washing machine...Imagine running the rest of the home appliances...

As far as I know Tesla actually uses Li-ion batteries in packs. Did you ask for the price??
Li-ion batteries typically get hot at anything above 2C. (meaning that if the battery is 3AH it will get hot at 6Amps load)
And they don't last for ever, it's the same type as the ones used in laptops. 3-4 years and you'd need new ones
Also these batteries need a lot of safety arrangements.

Only yesterday. Got a quote from one company and waiting on another.

My idea is to be completely carbon neutral and be able to live off the power I generate most of the time. Obviously, on cloudy days, where I’m not producing solar, the battery won’t be able to get enough charge for me to supply all my power needs at night so I will still be on grid and able to draw from the grid when needed.

Tesla is one of the batteries I’m looking at. Yes they are Li-ion.

The batteries don’t last forever but neither do solar panels. They typically last for 20 to 25 years. Warranty is for 10 years.

You recoup your costs within 3 years. Do worthwhile exercise even if you have to replace every 15 to 20 years.

The way things are set up in Australia, you can get an electricity credit from your power export rather than an electricity bill if you export to the grid.

My average power usage is 22 kw per day. The battery options are 6.5 kw or 13 Kw. So I can get half my power needs from the battery which comes from solar till the battery is fully charged and draw off my PV and pretty much be self sustaining.

I wanted to add more panels too but if I do that, I lose my Feed in Tarif which is extremely generous.

I have always loved new tech and always seem to be an early adopter.
