You can also just discharge the battery to the grid if you have excess (or soak up more from the cheap middle of the day grid power, although presumably there are charge rate limitations).
Comment on Spiralling costs spark 'urgent' overhaul of $2.3b battery subsidy scheme
Eyekaytee@aussie.zone 1 week ago
Other industry participants, who were not authorised to comment because of their work advising the government, said the scheme had created significant waste.
They pointed out that most households were only using about 10 kilowatt hours of power overnight and would struggle to fill a system with five times as much storage.
what are they talking about…
the average solar system is now 10kw’s, I have 6.6kw and can do 35kw in a day, on top of that what happens if you have multiple days of low sunlight? or in winter when you want the sun that does come through to last as long as possible
you want oversized batteries, they last longer as there’s less wear on them and the utility they offer (self-consumption) is increased
One critic said: “You end up with a lot of batteries that will never fill up, just sitting there empty forever, paid for by the Australian taxpayer.”
Why does the ABC not take 5 seconds to literally ask anyone with a bigger battery what their usage is like?

The misinformation is being spread on purpose. The more people adopt solar and their own batteries the less they rely on the power companies and the less money the power companies can make

The power companies primarily provide a grid, high availability and secondarily charge for power (which should be rapidly headed towards zero given renewable uptake). FWIW, I think the grid is a natural monopoly and should never have been privatized, and certainly the power companies are doing the the bare minimum of maintenance and bugger all expansion to cope with solar input and EV output. If they leave it get bad enough the Government will have to step in and do it for them, pure profit.
The real threat to power companies is people with a big battery have the option to go fuck it, I’m getting a genset and some diesel and disconnecting, which means they no longer have the entire population over a barrel and might have to provide some value. The real solution is to cut the Gordian knot and re-nationailze the whole grid (instead of statewide as it was), which will also be easier with the weaker bargaining position they have with a large battery population.

Worth looking into Ecoflows, I know they use them in Ukraine for portable power

Even a 4kw with solar will do >50% of your daily power needs and added bonus you don’t have all the noise and fumes that come with a diesel generator, save that for emergencies

Isn’t that just a portable battery with a solar charger (MPPT) integrated ? We were talking about solar roof setups combined with large fixed batteries, which will largely cover all your needs most days. The diesel genset I used as a placeholder for reliable personal electricity generation from some other mechanism for the rare other / high usage days. Biodiesel is a good option, but there’s hydrogen (or LPG) fuel cells and a number of other options, you don’t have to put them in the same room as you either.
Also kW is power, kWh is (stored) energy (kW you can deliver for an hour), units matter.
