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.

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

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
