Batteries are essential to off-grid solar power systems. The
batteries store the electricity generated by the solar panels for future or
present use (with an inverter), depending on customer needs. Renogy carries
three kinds of deep-cycle batteries: Absorbent Gel Matt (AGM), Gel, and Lithium
Iron Phosphate. Each type of battery has its own unique characteristics and
price points, making them appealing to a wide range of consumers. Below we’ll
walk you through some important points about each battery:
AGM:
AGM batteries are capable of delivering high currents on
demand and have a relatively long lifespan. This type of lead acid battery is
suitable for a wide range of uses, including solar and wind. The battery may
also be used to charge medical equipment. No need to worry about placing this
kind of battery in various positions, as it is valve regulated. Within this
type of battery is an ultra thin fiberglass that absorbs the sulfuric acid,
which makes it spill-proof. Like the other batteries offered, this kind
performs well in cold conditions (average winter weather, not serious below 0
temps). AGM batteries are great for budget conscious customers, as they retail
for less than Gel and Lithium Iron Phosphate.
Gel:
Gel batteries are also lead acid and valve regulated. They
have a long lifespan and are virtually maintenance free. These batteries hold
more acid than many of their counterparts due to their design, which reduces
heat transfer. These batteries have a 12 year floating design life and may be
used as a standby or for frequent cyclic discharge applications. Gel batteries
have excellent performance throughout their lifespan, dropping only near the
end of life. These batteries are suitable for solar, RV, and marine uses, and
may also be preferable for budget conscious shoppers. They retail for a little
more than AGM batteries.
Lithium Iron Phosphate:
This kind of battery is top of the line when it comes to
solar storage applications. This is a rechargeable lithium iron battery that
offers a longer lifespan, better thermal stability, and greater safety features
than the other batteries available at Renogy.com. It is perfect for many
deep-cycle applications including solar, wind, marine, RV, telecommunication
systems, medical equipment, and much more. It is lighter (25lbs), more compact,
and powerful than its other 100Ah counterparts. This battery also retains
higher voltage than its 100Ah counterparts. Budget-conscious shoppers be weary:
this is the most expensive type of battery we have.
