I have sump pump backed by standby generator and if my generator goes in a storm, I am sure getting flooded. And replacing a standby generator is around $10k anyway.
For me, the debate is spend $10k + maintenance/running cost for weeks of backup or 40k for 1.5 days. Heck no. I am sticking with generators.
If I can recoup the cost by playing TOU, I might consider battery, but 40k is still a lot.
Paired with solar, they can also be used to 'peak shave' when power companies charge higher rates during weekday afternoons, as many do.
'No' wise - it's not advisable to try to manually switch active panels from an installed / grid-tied solar system over to a unit like this, especially if you don't know what you're doing.
If you don't know what you're doing, or aren't willing to learn in depth, and be absolutely confident you know what you're doing, don't do it.
Don't do it either way, really - you'd be violating code and setting yourself up for a catastrophic liability nightmare if you do it, regardless of how confident you are.

This is a clean solution for those who don't want to put much effort into building a system. I would recommend you search YouTube for "DIY Solar Power with Will Prowse" to learn about how it all works and what are the best options for your situation. His voice is the only issue I have with his channel.

For diyers who know what they are doing 100kwh batteries on Aliexpress are $3.5k but they don't necessarily have all the certifications name brands batteries like this have.
I noticed that they ask for 2k for the install, can you let me know how did you find an electrician in your area that will do this kind of job?
Thank you.
My diy system, which I just put together this year, consists of 4 48v ecoworthy server rack batteries in a rack and an SRNE 10kw all in one inverter. My specs are 20.96 kwh storage and 10kw of continuous power vs. 18 and 7.2 for the ecoflow. A diy system is very easy to scale and is repairable should some cells fail or degrade.
I paid roughly $3300 for the batteries (rack was included) and $1555 for the inverter. With a few wires and a power distribution panel I have invested roughly $5000 for a system which outperforms this deal by a bit.
If all of the details confuses you it confused me a few months ago, too. It really isn't complicated though, it just takes some studying. I consider it a useful life skill to have and am glad I've learned it.
