I recently looked at buying a house that had rooftop solar installed, but they didn't appear to have any kind of battery solution. I did a bit of quick research into batteries, as I was thinking they might pay for themselves pretty quickly if I charged from solar during the day and/or from the grid at night during off-peak times, but it seemed like the ROI was higher than I expected, looking at 8-12 years using back-of-napkin math. Was I missing something here? I know it's pretty variable depending on your situation, but what is the expected ROI on a battery solution like this for a typical grid-connected home with rooftop solar?

I've been thinking about getting a backup battery but it will literally only be useful during power outages (specifically hurricanes) so it's not really worth the investment compared to the generator we already have.
The ROI depends on the cost of energy in the location you are. I pay .11/kwh, some pay less, many pay more. If you can generate what you use in a day, including storing your nighttime use in enough batteries to get you through the night that's a straight math problem. I personally look at the batteries as a backup power solution and not a cost savings solution. I have enough batteries to keep my house running for 24 hours, which is equivalent to about 8 of these sized batteries in this deal. The solar panels are the cost savings driver as that's where the "free" power comes from.
These batteries can qualify for the 30% tax credit that's going to end this year, but they need to be charged by solar and need to be put in service this year to qualify, so that helps with the math.
