Frequently Asked Question
What Kind of Battery do I need?
The most common type of battery used in a solar system is a lead-acid
battery. They are generally used because they have a low initial cost
are readily available. These batteries must be deep-cycle batteries. If
the battery is a shallow cycle or automotive type it will not function
correctly in the system. The deep cycle batteries are designed to
and recharge or cycle day after day for years.
The next decision is whether the batteries are sealed or
sealed battery never needs water added nor does it need an equalization
charge. The benefits of this battery are; the battery can be mounted in
any position and are easy to transport. The one downside is that they
to be monitored closely as to not overcharge. A flooded battery also
close attention. The water level needs to be checked often and
You will also need to perform an equalization charge, which is a long
controlled overcharge. This removes sulfation from the battery plates.
While this restores the battery's capacity, it can lessen the life of
batteries by warping the plates.
So you need to decide which battery fits your specific
needs. As long
as the battery is taken care of you can expect a long battery life
either battery type.
