BIG battery comments

[BruceS]

Hey!!
I know a chap who has a yard full of those "cheap wrecked EV's" !!
I bet he's rolling in the dollars!!
I already have 4 vehicles here so I really doubt any more would be welcome!
As soon as anyone tries to beat the system, the gate gets slammed shut.

Jon, the only hiccup with that is, is that you need a special V2G charger. That is Vehicle to Grid. Yet to be approved anywhere in Australa, and are rumours are they will be very expensive when approved.
Big issue is, most electric vehicles make 220v and some are 60hz, as opposed to the standard 230v and 50hz.
Better to just go off grid maybe.

What make/model is 60hz Dave? Maybe if you were to grey import a vehicle set up for a country that uses 60hz .... but that vehicle wouldn't charge on the Aust EV charging network either.

From what I've read .... and didn't understand much past "this is how it works" the same electronics that convert the mains 50hz at anywhere from 200vac to 260vac, to DC 400v nom. also works in reverse, up to the same rate as it can charge at, 7 kw ..... as to the 220vac 50hz, it seems to be somewhere in the computer that handles the charging/discharging, that sets and controls the output voltage ..... much like the Victron Multiplus and Quattro.
The work around is to charge the house battery from the V2L and feed the grid from the house battery ..... the smart way to do it is via the likes of https://specsolar.com.au/amber-for-batteries/
https://www.energymatters.com.au/renewa ... eighbours/
and many more that are signing up solar battery owners who want to sell through them to the grid ..... There is an app that constantly updates the price available to sell your excess power .....

Energy providers pay next to nothing because they work on you only having excess power from your solar, at the same time the grid is already flooded with excess power.

A company set up to be the middleman to sell your stored battery power, when the really needs it in your area, can get a lot better price and the more you have available to sell when the price is high, the more likely you are to be able to really cash in on selling any excess.

It's like being a day trader on the stock market, but you get to sell when you feel the price is good and buy when you consider it to be cheap enough to be worth it ..... if you have enough solar to generate your own, there is no value in buying ..... but if you bought cheap and have full batteries and there is a problem at one of the generators during the morning peak, you could make better than 100% on your power purchase just a few hrs ago, by selling it into the morning peak, then recharging from solar during the day ..... and again, sell for profit, you didn't have to buy the solar generated power .....

There is a reason all these big solar farms are installing big battery set ups, that is where the real money is to be made.

The East Coast Power generation system is on the edge of collapse. Coal fired generators were sold off to private companies that looked for short term gains rather than long term investment, so the plant they bought was Band-Aid repaired rather than regular shut downs for complete refits ...... that can only be done for so long, then the plant becomes unreliable and far too expensive to fix ..... no shareholders want to invest in coal fired generator mobs, so they are running them into the ground with zero care for just what happens to the grid if they can't provide or fail to bid to sell to the grid because there is not enough profit in it ......

If the electricity came from the investment you made in solar and stored in batteries, there is no reason you couldn't sell it cheaper than the coal fired power station .... or play the gambling game and see if you can sell just at the point the coal generators were waiting for, and get that high yield that they will be paid .....

I don't have the roof to fit the solar panels, nor the house to get connected to the grid and have a house battery installed and subsidised by the govt ..... but when I do

Amber is a wholesaler in SA, VIC, NSW and SE QLD this morning after 10am was selling power at 4c as all the solar was flooding in. This is when you can recharge your battery on the cheap to resell later and use your solar power to run the heavy duty machines in your home.

Will be looking at it more. Cheers

In SA, there are times during the day that power is free if you are signed up as a virtual power provider .... on some plans, if you have enough capacity, they will actually pay you to store power from the grid during the peak sun hrs ..... but they want it back during the evening peak ...... nothing is free when SA Power is involved

Terry, from my understanding some of the early MG's were, and maybe the Hyundai. I am led to believe that a different resistor in the genuine charging lead tells the inverter how many Hz to output I don't know for sure, it's what I have seen on a few EV forums.

The resistor tells the system how many kw to limit the output. Genuine MG have limited the output to 2kw @ 220vac to avoid getting into problems with people trying to power their house through a 10 amp lead. By changing the resistor, like I did, it will provide all the way up to 7kw and still maintain the constant 220vac but I don't have anything I can measure the frequency with .... all that went in the fires.

I had a Google look to see which countries used 60hz:

Countries that use 60 Hz electricity include the United States, Canada, Mexico, and most of Central and South America, along with Japan, South Korea, and the Philippines.

Japan was a surprise, the rest are the result of American influence .... the rest of the world is 50hz apparently, so anything out of China would be 50hz I'd presume.

Terry, your year model MG4 should be 50hz. I checked that ages ago when it seemed your MG wasn't talking to your inverter. It's the 220v compared to maybe 230-240v from inverter that has caused you 'minor irregularities' shall we say.
The earlier ones may have caused a few problems, but if you only use it (a 60hz version) to run a kettle or toaster or something without electronics then it shouldn't cause too much grief.
