Batteries: How cheap can they get?

Australia has become SO competitive for solar and battery installation you can actually be fairly safe nowadays just picking any old supplier that has >4.7* on google and there'll almost definitely be <10% price difference (that's the WA experience anyway).

Going with a door knocking sales rep for home batteries would be madness in most countries but chances are pretty good that in Australia you would get a perfectly decent product.

Despite what you get in Australia being pretty reliable, it's too expensive to justify quite yet. My 8kW solar is connected to a Fronius inverter, but until I find a less expensive option I can justify adding a battery.

A 13kWh system is over $AUD10k, and the ROI is on par with the expected lifespan of the battery.

If sodium cells can bring the price down to $AUD100 it would indeed be a massive game changer.

Yep I agree - I will, however, be happy to install a battery if it doesn't save me money but does represent a carbon price of about $100/tonne

If you’re in NSW there’s a state government subsidy of $2800 later this year for home batteries.
