Does Anyone Have a Whole House Battery Backup Instead of a Generator?

It's a battery backup that can power a home for up to 3 days. Seems these things are popular in the Houston area.

There's even a Houston company that will rent out the system. $695 + $20 a month rental fee.

Hell no. I want my house to run like normal during an outage not run a couple of lights for 3 days and fridge for 3 days then I’m fricked.

I looked into base because they kept sending shite to my house and it runs the ac for a couple of hours

Went with a 26kw instead.

3 days of lights and fans, sure.
plug in your fridge and a freezer and you might get a day out of it, at most. and don't think about using the coffee maker, or microwave, or blow dryer.

Most of them can't even deliver enough continuous power to run one 5 ton a/c unit, and the ones that are capable of delivering that much power can only do so for an hour or so.

and they are expensive as frick.

I feel like those would work great if you also had solar panels. Or am I wrong?

For minor outages, certainly useful. If I had the space and time I'd have a hybrid system with batteries and a stand-by generator. I've been looking into building my own little setup with some deep-cycle 12V marine batteries and a big pure sine inverter that could run my fridge and freezer for a little while during a minor outage before having to run my generator. Something I could keep plugged in on a float charger then roll out.

I don't know much about these systems, but what if you had some sort of charging capability, like a small windmill or solar panels continually charging them. Would that be able to power an entire house, or is it just that the battery power is too low?

I'd assume they'd charge off the regular house electricity.

They are basically just a bigger version of an uninterruptable power supply you'd have for your computer, stays charged on the mains supply until the power goes out and it clicks over.

Those exist, but you also need several solar panels and the space they take up adds up quick. I was looking at a system at my office to run the servers and security system during outages. At the time, the system that would fit my needs would set me back about $9k to give me 12 hours of back-up time. I would then need 7-12 solar panels with each needing a 6’x4’ footprint, which would be another $2k - 4k in costs; plus the labor to install.

It’s really pointless unless parked with solar to recharge them.

But it will work. And there may be a rate arbitrage benefit depending on if you’re in a time of use area, but it.l never ROI out without solar too.

FYI I monitor over 100k PV and storage systems. So ask any questions.

Also Base is fricking junk. They would never make an approved vendor list I would take on.

Yes, I do.
I have Tesla solar panels with 3 batteries.
Works seamlessly when power goes out. Many times I'm not even aware we lost power.

When I fill the batteries, I then sell elec back to Tesla at market rates.

A couple of yrs ago, when it was extremely hot here on Magnolia, I had credit balances as I sold more elec than I purchased.

I wouldn’t let someone put solar panels on my house if they told me it was free install and I would no longer have electric bills.

That shite is an instant turnoff when I see that shite on a house and I’m looking to buy

I’ve considered the battery backup route. I figured I’d have to also install a backup split AC unit in the kitchen so it could run that vs the central air. Although it would only be an intermediate solution. In a few years when we are older we may have medical equipment, if so we’d have to get a gas. Basically we decided to save the money for when we need it, and not to save $500 in groceries from Costco.

Nope but I do have lithium batteries on various things I built for fun that could keep fridges running for a couple days if need be. I don’t live in a hurricane area though. Any outage over an hour would be a once in a lifetime event.

They’re not attractive that’s for sure. But they do work and it’s the only truly off grid option.
