Batteries for Buildings
This is one of my keen interests - batteries for buildings; and they can help save money and energy, with or without solar panels.

I got a forklift battery for my house, but I'm only using it for emergency power.

Nice! Is it massive lead acid, or something else?

Nice shop! Perf-metal cubicle walls and planters hanging on the handrails.
The grid buffering aspect is interesting. With lots of these all over, local disruptions would be constrained.
OTOH the smart meter part is a problem. Using wireless to control a wired connection?

Data rates and distance limits vary widely over many power-line communication standards. Low-frequency (about 100–200 kHz) carriers impressed on high-voltage transmission lines may carry one or two analog voice circuits, or telemetry and control circuits with an equivalent data rate of a few hundred bits per second; however, these circuits may be many miles long. Higher data rates generally imply shorter ranges; a local area network operating at millions of bits per second may only cover one floor of an office building, but eliminates the need for installation of dedicated network cabling.

For off stationary off grid power I'm sticking with lead acid.
Unless some day I gut my leafs pack.
But lead acid are really bad for grid storage since they are typically around 80% efficient at best.

I'd still give lead-acid a chance for stationary applications, since those are less weight-sensitive. I'd consider those Optima batteries if I were going to install an off-the-grid setup at home.
