Storage Devices
solar power inverter
panels do not generate enough electricity in real-time to power people's
devices, nor do they generate any electricity at all once the sun goes down. To
overcome this problem, we must incorporate the use of a power storage system,
namely batteries. The most important piece of information about batteries is
that they are 12 volts, a fact that determines the desired voltage output of
nearly all solar panels. A second essential piece of information about batteries
in solar power systems is that they must be what are called deep cycle
batteries. Deep cycle batteries are specifically designed to be charged up and
then full depleted, over and over again. If you did this, for example, with
standard automobile batteries, you would destroy them quite quickly. Finally,
as one battery is not enough for the needs of most systems, one must wire a
host of batteries together. This group of connected batteries is called a
battery bank.
Charge Controllers
A fully functioning array of power inverter panels will produce great
amounts of electricity all day long. Sometimes, though, our batteries are fully
charged, and if fully charged batteries are fed a steady current of
electricity, they will become damaged. It is necessary, therefore, to install a
device that can determine the level of charge in a battery bank and then use
that information to regulate the amount of energy sent to them. The device that
does this is called a charge controller.
