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 panel includes a 10 amp MTTP charger.
To be sure of long lifespan you have to do proper maintenance on the battery. A charge controller is necessary to protect the battery.
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 panel with connecting cable.
Battery Clamps. (Alligator)
Some wiring and adaptor.
A 10 ampere controller.
The 20 watt Polycrystalline panel can generate
cheap electricity. Face at the sun and it operates.
The ultra-bright green LED will show you when the system is charging. It gives an indication of when finished and ready to be used.
Use the stainless steel mounting screws for a permanent installation. They include the screws in the kit.
With 6 hours daily sunlight the solar
panel can 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-Circ Voltage (Voc): 2.6V
Optimum Oper Voltage (Vmp): 18V
Optimum Operating Amp (Imp): 1.12A
Short-Circuit Amp (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.
For full operation of the 20 watt solar panel we must have a charge controller as well as a battery.
The 20 watt module comes with a 10 Amp charge controller.
For sizing of the battery we divide the total watt by the volts.
Depending on your area, you take 6hours sunlight X 20 watts) X .85 to allow for loss/ 12 volt x 2 for D of D. We assume a DOD of 50%.
20 x 6 x .85 divide by 12 x 2 Gives 17 Amp Hours .
We can use a 20 Ah battery.
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 module comes with a MPPT 10Ampere Charger.
It pairs non-matching voltages that come from the batteries and the panels.
These MPPT controllers can adjust their input, and can vary output power. This ensures maximum power generation.
The MPPT controllers are higher in efficiency than P W M controllers.
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.
They manufacture the panels come with strong aluminum frames.
They make use of low iron high transparency tempered glass.
It allows for higher light transmission and better transparency.
Always make certain the cables are undamaged.
Use a damp cloth for cleaning of the solar panel.
A clean panel is more effective.
Buy this the panel to maintain a 12 volt battery.
It maintains rechargeable 12V batteries. Also for many different applications.
When you use the controller you can connect the kit permanently to the battery.
It is best to connect the charge controller first to the battery. Only after this you can connect the 20 watt solar module.
When you disconnecting; first the solar module. Then after that the charger.
This correct connecting always ensures faults free and safe operation.
The 20 watt solar panel and charge controller operate as described.
It is well constructed and affordable.
