Most home storage is Lifepo4, rather than lithium ion.
It’s a bit more expensive, and only has 80% of the capacity. In tradeoff, it gains 3-5x the lifespan, and an inability to burst into flames.
Bigger brands tend to be more reliable in capacity and lifespan. Cheap ones are more hit and miss. It might be fine, it might fail after 3 years, rather than 10.
The best setup would be a dynamic electricity contract and solar panels + batteries + heat pump or airconditioning, optionally EV.
Using only batteries will lead to diminishing returns because of the surge in batteries everywhere, having an overall stabilizing effect on energy prices throughout the day.
Store the excess PV energy in batteries during the day and, at times when electricity is expensive, sell it or use it for home appliances, heating or EV charging.
Not the same guy but I’m having both installed right now. I’ll be buying cheap electric at night to fill my batteries and running the house all day from that, while exporting and selling anything from the solar as well as any excess.
Every unit I sell is worth 12.5p, the cheap rate is costing me only 5.2p. eventually that export rate will go away, I’m which case I’ll be able to be self sufficient about 2/3 of the year.
Yep, that’s me. Cheap battery, reduced my monthly bill by 75%.
What’s a “cheap battery” gonna cost me?
I’m the UK, 10kWh from a large brand (sigenergy) costs about £2k, but cheaper brands you can get about 3x the storage for that price.
What are the drawbacks or tradeoffs for cheaper brands? The recent Lumafield report on lithium ion batteries was horrifying.

Thanks! I’m more in the $100’s kind of budget.
Are you just storing electricity from the grid when it’s cheaper, or did you do solar as well?
