I have a Tesla power wall as part of a solar system (you ideally want to do it with solar because that makes it tax credit eligible). The post-tax marginal cost of the power wall was only $6k with the solar.So Tesla website claimed up to 13 hours with 2 powerwalls for around $23k including install.How many hours would a Tesla power wall system provide whole house power?We have a 2200 sq ft townhouse on the Gulf Coast.
We have a small L shaped backyard. I basically dragged a permanent generator installation company out here against their will few years ago and they said no room for permanent generator.
We also have an HOA.
Looking for whole house power backup (2 ACs etc) solution that could work, seems Tesla PowerWall might be good option at least for <14-15 hour outages that could be installed completely indoors.
One quirk is that our circuit breaker is in the backyard not in the garage. So not sure if they would want to install outdoors anyway requiring HOA approval etc.
Any thoughts re Tesla Powerwall for this situation? Any good alternatives? Yes I am aware could buy gas generator but I think in the storm situation it would be prone to theft if left unattended outdoors.
Thank you!
how large would that system be for you and how much would it cost?
3 powerwall units for 24 hours for "whole house" vs only essential circuits?

This is before anyone comes to look so who knows what ends up happening at that point.
I agree not very cost-effective for sure but DW doesn't like idea of power going out and DS is 3 years old.
We had one really bad outage 3.5 years ago when DW was pregnant, and scattered recent ones lasting a few hours which were significantly disruptive to DW.
I was hoping for some kind of solution. We can certainly afford $23k for peace of mind.
If we evacuate, DW also wants fridge running, not sure if 2 powerwalls might be able to do that if everything else is off for a few days.
The estimates they give are really sans HVAC. You aren't going to get more than a few hours out of a power wall running a central AC. With my dual units, one power wall would only last ~2 hours running A/C in summer. My system is setup to bypass the A/C circuits for this reason. However, I can run a small window unit in the afternoon during an outage (uses substantially less power than the central a/c).
