There is a better way.
Once upon a time, I followed all the advice I could get my hands on
concerning solar, wind, batteries, controllers, inverters, the science
of wire distance/drop, ad infinitum and nauseaum. So just like
with only one view that regurgitates itself all over the Internet, I
built that large battery bank. This
did NOT work for me.
I tried 12v banks, 24v banks, and 48v
banks. I tried using
different gauge wire, building a couple of solar trackers, and more.
Here's what works.

battery in time of unexpected need.
The first micro battery bank made
accident. After moving a bank of batteries that no longer were expected
to be needed, I became busy with other projects. Having left
two solitary 6v batteries in series created a solitary 12volt
"battery", also left were only two lights connected to the
battery (12v 16.5'
strip lights). I
was pleasantly surprised that weeks later, the single battery (6v
x 2 = 12v)
was looking pretty damn good (unlike the other battery banks which were
much larger yet by morning were leaning to the 12.2v mark). Having the
lights and solitary battery had suddenly
become appreciated because I needed light within the location at the

That bank has been running
on maintenance-free auto-pilot for years now without ever a hitch!
Consider those micro battery banks as
your insurance. If ever needed, it's an easy task to pool
your resources, and if that day should arrive, you know your batteries
will be healthy and fully charged due to their load being light (no
The voltage following each night at that first micro battery bank is
the highest of all the other
battery banks when checked pre-dawn. Whereas the other battery banks
range around 12.3v or 12.2v or 12.4v (under loads) by dawn, the
micro-battery bank showed higher!
When a battery bank can go a week without sun or other power
input, that's a "done" battery bank, now leave it alone and go
build another one. This is advice for Ohio climes, in Florida,
Arizona, Southern California, etc. only a few days are requisite due to
their possessing more hours of reliable sunlight.

Imagine this scenario:

However, if one solitary cell should go bad in that power bank, your
entire house is
thrown in an unreliable state.
Let's say for instance that
one of your appliances, a large inverter for example, went bad due to
short. That solitary short can potentially affect your
entire bank's energy, hence your entire home's energy.
Whereas a micro battery bank is easier to
troubleshoot, remedy, and it doesn't take down your entire home!
If one of my battery banks ever incurs some unforeseen problem, it
require a great undertaking to not only identify early on (before the
damage), but also, in a
pinch I can always jump the load to another battery bank while the
problem is figured out.
Furthermore, if the battery bank is 12v, in a pinch, I could use a bus,
car, tractor, or other emergency boost to bring up the battery bank if
it ever came down to a dire need.
