Replace bateries with cement . This will get your attention for sure

 I know absolutely nothing about the systems you guys are talking about
and I am new to this group but I am not stupid and would like to
venture a question.

From reading your messages I conclude that, batteries are most of the
times, a necessary pain in the neck ,they  have a limited life, must
be matched etc. etc.

Why not use a different way to store energy?

Why not store the energy using a mechanical system? I am not talking
about springs or torsion bars, I am thinking of gravity.

Make one or two very large boxes of cement mechanically suspended on
the side of the house ( the side without windows) and use the energy
you want to store to lift that contraption. You know the rest.

Modern electric motors and generators are today rated at more then 90%
efficiency and that is probably more than what you can get from
batteries.
The boxes under the eaves may even collect rain and increase the
weight of the contraption and if you don't like the looks, you can
build a wall to hide the full assembly.
Easy to seee how much energy you have in storage.

Once my manager asked me to design a TV station. Why me- I asked  I
know nothing about TV stations .  That's why , I am tired of seeing
the same thing over and over again,

Please no insults. It's Sunday

  I tried that method and my house tipped over and ruined it. Show us
your design. The hydro electric pumping plant uses your method at
Niagra Falls in Buffalo NY

You don't attached it to the house. If I have to shown you a design,
you don't understand the idea.
 Have you heard about electric cars that generate power when they go
down hill?  That's the same principle. They use power when they go up
and may return part of  it on the way down the same hill.

A full  elevator going down may not use energy. It may even convert
part of the energy used to go up into electric energy coming down.


That's a different subject

 Yes, and the the eneryg that they generate is stored in batteries.
