The 20 watt solar panel will ensure many operating hours. It will keep your battery in a tip-top condition. You will enjoy trouble-free operation for a variety of applications.
The solar module comes from Suner Power. The 20 Watt
solar module kit also includes a 10 amp MTTP charge controller.
Proper maintenance of the battery ensures a much longer
lifespan. The charge controller protects the battery from any surges as well as
This product is a solar-powered battery maintainer for 12V batteries. You can also use it as a battery charger, but charging will take a while.
A Solar Module with connecting cable.
Battery Clamps. (Alligator)
The 10 amp charge controller.
The 20 watt Polycrystalline panel is ready to generate
cheap energy. Direct it to the sun and it is in operation.
The sun will do the job and the ultra-bright green LED will show when charging. It indicates when finish and ready to use.
If you want to do a permanent installation you have to
use the stainless steel mounting screws. The screws come with the kit.
If you now have 6 hours of sunlight per day the solar
panel will produce 6 x 20 = 120 watts per day.
Allow for a 15% loss. Then you get 120 X 85/100 = 102 Watt.
Forget about the two and you still get a fair 100 Watt.
This is more than enough to maintain a battery.
Maximum Power: 20Watt.
Open-Circuit Voltage (Voc): 2.6V
Optimum Operating Voltage (Vmp): 18V
Optimum Operating Current (Imp): 1.12A
Short-Circuit Current (Isc): 1.17A
Weight: 2kg .
Max wind/snow load. 2400Pa
Backed by extended 12 months warranty and lifetime technical support.
Use it for a gate opener, electrical fencer, cars, 4WD’s, trucks, motorcycle, marine, boats.
Also, use it for farm equipment or any application where you use a 12v battery.
To make the 20 watt solar panels fully operational we need a charge controller and battery.
The 20 watt module comes with a 10 Amp charge controller.
Size the battery by dividing the total watt by volts.
This is 20 watt x 6 hours sunlight ( Depending on your area.) X .85 for losses/ 12 volt x 2 for DOD.(Depth of discharge.) Assume DOD of 50%.
This is 20 x 6 x .85 / 12 x 2 = 17 Amp Hours .
A 20 Ah battery will be a good choice.
The colorful LED indicator indicates various statues of
the batteries while charging. As well as the state of the 20 watt solar panel.
They use a red and green color at the different
sequences. This is to show specific conditions of battery and solar panel.
The 20Watt solar panel uses an MPPT 10A Charge
The MPPT charge controller can pair non-matching voltages
from panels and batteries.
These controllers adjust their input. That is to bring in
the greatest power possible from your solar array. It also varies their output
power to match the battery that you attach to the system.
The MPPT controllers are thus much more efficient. This
is the Pulse Width Modulation controllers.
It utilizes the power of your solar panels more effective
when charging a battery.
It comes with an alloy ball. This is to adjust the angle of the solar panel.
Adjusting the angle provides for the largest output for a longer period of the day.
Mounting is easy to do.
You can mount it on a horizontal surface or vertical wall.
The panels come with heavy-duty aluminum frames.
It uses low iron high transparency tempered glass.
The low iron glass allows higher light transmission as well as high transparency.
If you want something for maintaining a 12-volt battery
this is the panel to buy.
It will keep your batteries charged. It can maintain any rechargeable 12V batteries. Also for a wide variety of applications.
When using the charge controller you can permanently connect the kit to the battery.
It is important to remember to always connect the charge controller to the battery first. After that, you connect the 20 watt solar panel.
When disconnecting you first disconnect the solar module. Then disconnect the charge controller.
The order of connecting and disconnecting is important. It ensures safe and faults free operation.
Always follow the necessary safety instruction. Also, ensure correct polarity when connecting for safe and proper functioning.
The 20 watt solar panel and charge controller do what the manufacturer says it will do.
The high-quality solar module is well constructed and affordable.
The module is worth the money.
