It's true for me, 6.6kw solar system, 10kwh battery, I pretty much never run out of of power now, my grid usage is background noise
Impressive. Can you share your setup costs and general location (I..E region / country)?
Australia but it's not really applicable to other places, we now have strong gov incentives to get solar (STC's) and batterys (battery rebate):

So plenty of sun compared to countries way up north
I’d be curious as well. I’m looking at batteries but my consumption is 80% in winter when whatever the capacity I install I’ll end up using the network :-/
do you have time of use charges?
if it’s more expensive to use power at night people are filling up during the day and using it at night, bit of electricity arbitrage
It’s the reverse currently, off peak after 10pm and the weekends. Definitely possible to edge that way during wintertime but the cost differential isn’t so big so the roi is definitely not great.
