Tip #9 Consider DC to
DC; as opposed to DC to AC to DC
Alternative title: No
If you are on a budget, DC to DC is the answer. Many Get their panels
and batteries then plug in a large inverter that pulls the voltage
created by the batteries up to 110v.
Using a large inverter to handle your
entire life's electricity consumption is blindly having faith that the
inverter will never break down.
If you simply must have inverters, at least use a bunch of smaller,
cheaper units (the larger ones are outrageously priced and putting all
your energy requirements into one inverter is risky). Similar to the
advice to choose micro battery banks over macro, so ought to be your
mindset toward inverters. If a micro-inverter ever goes down, simply
piggy back to another inverter that is still working. voilà, mom lives!
The loss of a micro-inverter doesn't break a budget to replace.
Whenever possible, DC TO DC without the
DC to DC is tantamount to zero phantom loss (not counting distances or
mis-wire-sizing). Why would you want to charge a battery bank at one
voltage, then step the voltage all the way up to 110v, only to have it
step-down to the exact voltage you started with?
If it's a 12v appliance that you are needing to power, simply remove the
step-down converter, split the wires and voilà....no more potential
problems of a step-down converter going bad on you.
Converting electricity from one extreme to the other is needless loss.
This is not to say that inverters aren't necessary for some items and
appliances. There is a 48v battery bank here with a 48v inverter powered
by a 48v solar array which has been an upgrade to running the deep
freezer off of the 12v battery bank (converting from 12v all the way up
to 110v is quite a hit in of itself upon the battery bank).
When mainting the lawn I've noticed that the electric weed whacker is
definitely out-performing the previous years pulling from a 12v battery
bank. The washer spins faster also. The advantages still cannot outweigh
the cost. For instance, if one of the batterys of the required 8 (6v x 8
= 48v) should fail or short-out, the entire bank is down until the
problem is remedied. Whereas in a 12v bank, I merely pull it's partner
battery in the series connection and go back to weed whacking (6v x 2 =
Another potential disaster is the "what-if" field. For instance, what if
a solitary battery should go down? It's no easy task for an old person
to rearrange batteries, or rearrange wiring, to obtain some voltage that
is needed at the time. In other words, if the 48v battery bank is
completely down, I can't even readily connect 12v items in a pinch,
rather it ends up being an all-nighter or similar undertaking.
The 48v conversion (solar, battery, inverter, and controller) was
entirely completed in 12hours of straight unadulterated work. One thing
led to another and before you knew it, I was replacing all the wiring
for 4gauge/awg). The conversion had alerted me to a problem that
otherwise may have gone undetected for many more months. One of the feed
wires from the quick-disconnect was black and burned, the jacket of the
wire was blackened, and in all there were about an inch of affected

Batteries Plus is a much appreciated business in that they make
batteries readily available. H O W E V E R , I do not appreciate
learning that the Duracell Deep Cycle Batteries are deceptively in label
only. The reason I found out about this scam was due to the need to
ascertain the pwm of the sligc125 batteries they sold me. The Batteries
Plus agent didn't know so I called Duracell (which you can also do to
verify this fact). Duracell stated that the batteries are not made by
them and that Batteries PLUS simply bought the label (WHATEVER THE HE
that means). BUT THE PLOT THICKENS! I then called back to Batteries Plus
and this time an agent pointed me to Deka Battery's website stating that
Deka actually makes the battery that is labelled as Duracell sold by
If I wanted a Deka Battery I would have purchased a Deka Battery.
Deception is criminal when the upper elites are busy judging our every
move and thought, yet when BUSINESS is involved these days, it's a
virtually untouchable matter unless you have many hours to toss your
life toward in stopping the deceptive practices of business.
Imagine if this scenario played out at our level, me to you for
instance. If you came to me and purchased a Dell computer, and I even
tell you in the sales pitch it's a Dell computer, and the label in the
front of the computer is an authentic dell computer emblem, wouldn't you
be completely beside yourself if much later you found it to be a
crappy-brand-computer and not a Dell? I'm not saying scams like this
don't exist at the street-level of the class system, but what example
does business or polity (or the ever-present judiciary) set to the rest
of us by these deceptive practices? What does one tell the next
generation, Don't steal or Defraud others (and then mum's the word when
the upper class is doling out just that)?
This is the myopia of business in 2018. My advice to business would be,
"kick rocks", time's are tough for all of us but to lose all of us would
be the loss of all business. The adage "You never know a good thing till
its gone" applies. It may not be great, but its still better than you're
going to find with US gone. (*I actually am paraphrasing Revelations,
primarily the part of what happens to the whore that runs off to the
desert place...in short, it would have been better had they died with
the rest of us).
Bad business begets bad business. Changing names is deceptive (and USED
to be illegal).
