Powering The System
If power can’t be provided easily through an extension cord then other sources
have to come into play. An easy fix is a portable generator. There is a massive
amount of generator options to choose from and for the most part it needs to
be portable, quiet, and provide the power needed. Figuring out the power
requirements is just a simple exercise in math. Portability is up to the judgment
of the person that has to pack the thing around but noise level can be
something that others will most likely have a strong opinion about.
What is quiet to you might be a “Battle Heavy Metal Acid Rock Bands” or a
low flying squadron of 747’s to someone else. In this day and age of people that make a sport out of
complaining about something, best check ahead of time as to what the rules might be if any before
taking a long trip to some star gazing venue that is not in your immediate backyard. Make sure to
use a Surge Protector or UPS (Uninterruptable Power Supply) between the generator and your
system. Generator power can be “dirty” and a Surge protector or UPS unit will clean that up.
Another option is a large DC
Power Cell hooked up to an
Inverter that converts DC power
to AC power. You have to figure
out how many total watts in
power your system will need.
Add in an additional amount for a very comfortable buffer and go find an Inverter along with some
Heavy Gauge Power Cables that meets or better yet, exceeds those requirements. Remember you are
still using a “battery” and they have a limited run time of power.
