They don't provide any backup, they are purely to make your grid power-meter spinn slower or sometimes even feed back into the grid (when allowed).
The cheaper versions do make economic sense in countries with high electricity costs for home consumers, but its not a "great investment".
Yeah. It seems like a cool idea, but I can't quite understand the ecenomics being it.
I can see it being used as a "trial run" for people considering going solar or off grid in the future, it can be a safe first step, as the parts of these kits would integrate with the whole home systems sold by these same companies.
You just hook it up and your electricity bill will be lower next month. Not sure what is so complicated about that :) I don't think most people are considering it a trial run or plan to upgrade if they live in a small rented apartment with only a balcony.
But if your expense for the power station is higher than what you will save on the electricity bill you are actually losing money. Especially if you consider batteries lifetime, you can risk throwing the whole thing away before you saved enough bill money to recover the expense. So there are cases in which simply paying the bill is cheaper. I did the math a while back for my house and I would break even in like 7 years, which gives me only 3 years of actual saving before the battery wears out.
This has been my problem, the cost vs savings doesn't math yet. It gets a little closer every time I check though.
