For people who are installing solar panels installed it seems like it may actually be feasible to have a pay off period less than the 10 year warranty if you consider that the new powerwall will cost the basically the same as the powerwall 2 but not includes an inverter built in which is 11.5kw inverter which would be roughly 3k for a decent on here?
what are peoples thoughts on this worth getting if you have three phase power and getting panels installed?
Power bill will only keeps increasing in future.
Are you assuming Albo will stay in power?
Are you assuming that power bills never go up under the Libs?
I never mentioned the Libs.
What if you would like to use the AC to heat or cool your house at night but couldn't justify paying for it, but you now can justify it with fancy battery because if you don't use it all yourself then you'll only get 5 cents for it feeding it back into the grid.
"worth" is subjective to each situation.
Foe me the 'worth' is the energy sovereignty of making my own power and not being subject to the power outages or the conditions of the supplier. EG the turning off of solar when the duck gets bad.
For others it's the ROI and only looking at the $
The best use case is to consume the energy you create during the day after filling up the battery and then trying to use the battery in the evening.
Have as many panels as the unit will take as the buyback is not really worth it.
my thoughts…
Powerwall looks to be over $10k for 13kW. For most people, the pay off is too long.
That said, hopefully the price of the batteries reduces and there's more competition to push the price down. Some EV's have the ability to connect to the house's supply so that is an option into the future.

That's the time most people would want to be charging their car though.
It's surprising. to me that there aren't more competitive options already. Sodium-ion batteries are much cheaper to produce than Lithium-ion at the expense of lower energy density but if it's something going on the side of a house instead of in a car, that should be an acceptable trade-off. Non-flammable too.
yeah hopefully the sodium ion batteries will come soon, but the powerwall 3 has lfp batteries making less suspectible to fires anyway due to a lower operating temperature.
yeah apparently with the powerwall 3 it will have vehicle 2 grid with telsa cars also, so another selling point as currently the next v2g adapter for the nissan leaf costs like 9k i believe.
just an update, apperently this may not be sold in western austrlaia as its a 11.5kw single phase which is not allowed here. For some reason they dont offer a three phase version :(
In other news huawei will sell an inverter that is combined with a battery that will be offered in three phase which i imagine will be offered at a competitive price to teslas.

UPDATE: that was an error its a new battery from huawei with a 15 year warranty that works with a huawei inverter, its not combined like the powerwall 3
I think it depends on how much is your power bill. If your bill is over $1000 per quarter I believe it is worth the investment. Power bill will only keeps increasing in future. I have solar panel and battery which reduce my power bill to average around $50/quarter. We use to pay around $250/quarter when we live in a unit.
