LiFePO4 12V80Ah Battery Integrated BMS And MPPT for Solar Street
Light
Solar street light is not only energy saving and environmental
protection will not produce electricity,In the past, many solar
street lamps used lead-acid batteries, but now, almost all of them
use lithium batteries.
Advantage
1. Lithium batteries are small in size, light in weight and easy to
transport.
Compared with lithium-ion energy storage systems and lead-acid
colloidal batteries used for power solar street lamps, they weigh
about a third and are a third by volume.
That makes it easier to transport, and the cost of transport falls.
2. Lithium battery has high energy density and long service life.
Energy density refers to the amount of energy stored in a given
unit of space or mass.
The more energy density a battery has, the more power it can store
per unit weight or volume.
There are many factors that affect the service life of lithium
batteries, and energy density is one of the most important internal
factors.
3. Solar street lamps using lithium batteries are easy to install.
The installation of traditional solar street lamps needs to reserve
a battery pit, and the buried box will put the battery into the
sealed.
And the installation of lithium solar street light is more
convenient, you can directly install the lithium battery on the
bracket, the use of suspension or hidden type.
4. Lithium-ion solar street lamps are easy to maintain.
Lithium-ion solar street lamps only need to take out the batteries
from the lamp pole or panels during maintenance, while traditional
solar street lamps need to dig out the batteries buried in the
ground during maintenance, which is much more troublesome than
lithium solar street lamps.
ECOLITE produces LFP12V80AH battery pack, specially designed for
solar street lamps.
The service life is up to 20 years.Be brave of any inclement
weather.
