You can buy the kit for $2,500. Using my rates and usage, it's still not worth it.
Monthly savings
$21.25
89 kWh offset
New est. bill $90.01 down from $111.26
Annual savings $255 per year
9.8 yrs to break even
What size of unit did you calculate with? Typically the ones sold in Europe are below 1000€, some even as cheap as 600€.
It's all on their website:

You can probably order one for half the price 🤷
