Batteries are the heart of an independent power system. They store electricity
for use at a later time when a charging source is not available. They also provide
a reserve of available energy to run loads that require more power than that
provided by the renewable energy source.
Batteries wear out and must eventually be replaced. Regular monitoring and maintenance
will extend the life of your battery and save you money.
How you use and maintain your battery bank will have a direct relationship to
their lifespan. The deeper you discharge these batteries, the shorter their
lifespan will be. A battery bank that is too small will tend to be discharged
deeper. Your battery bank is a long-term investment. Consider how you might
want to expand the system in the future.
