  • ☀[Charge Visualization]The indicator lights can help you understand the charging status: the blue light is on (put in the sun), the red light is on (charging), and the green light is on (charging is complete).A short circuit occurs and all three indicators are off.
  • ☀[Intelligent Protection] Built-in charging microprocessor, improved charging algorithm, can provide overvoltage protection, overcharge protection, short circuit protection, etc. It can prevent reverse charging and can be safely used for charging and maintenance of 12V batteries.
  • ☀[Higher Conversion Rate]The regular convex points of surface distribution are conducive to the secondary propagation of light, absorb the radiant heat of solar energy to a greater extent, and greatly improve the photoelectric conversion efficiency.
  • ☀[Widely Used] The included 3-piece SAE cable kit is plug-and-play,it can be used for cars and 12V batteries. Comes with carabiner and suction cup to meet your different installation needs. Suitable for automobiles, RVs, motorcycles, ships,snowmobile,etc.
  • ☀[More Durable] The PET material can be waterproof and dustproof. A layer of epoxy board is added as a bottom plate, which is more sturdy (the broken panel will cause the charging efficiency to decrease). You can contact us at any time if you have any questions.

Product Description

20W Flexible Solar Panel Kit For 12V Battery Maintenance & Trickle Charging

Why We Need a Solar Trickle Charger or Battery Maintainer

  1. Batteries consume power slowly and car batteries will discharge automatically when the car is not used for a long time
  2. If the battery is completely depleted, even if it is fully charged again, the maximum capacity of the battery will be reduced
  3. The battery life will be reduced if the battery is not used and charged for a long time. 12V battery whose voltage is not kept above 12.4V has the possibility of sulfation, which is the main reason for the failure of many batteries. It is the knowledge of this knowledge is very few people, so the battery life will be shorter and shorter if not used for a long time.
  • This solar panel kit is mainly used to maintain the 12V battery and trickle charge the 12 battery to extend the life of the battery throughout the year segment.
  • This 20W flexible solar panel kit is also suitable for small off-grid systems, and the kit includes various types of adapter extension cords, making it ideal for newcomers to the solar panel category.
  • Unlike other controllers that consume power at all times, our 2022 upgraded built-in controller does not consume power at night.
  • This 20W solar battery charger provides full protection for all types of 12V batteries from overcharge, overvoltage, anti-reverse charge, over discharge, short circuit, etc.
  • This solar trickle charger is made of high quality monocrystalline silicon solar chip cells, with a solar charging conversion efficiency of up to 30%.
  • The battery panel surface is made of PET which is different from others to achieve more than 2 times of solar light reabsorption, further improving the solar energy absorption efficiency.
  • The panel body is made of high quality EVA material and PCB backplane, which provides IP67 waterproof rating for this 20W solar panel, ideal for outdoor use, and the high quality manufacturing material greatly extends the service life of the solar panel.

Focus on research and development of solar products.

Continuously improve and provide higher quality products.

Solar Battery Trickle Charger Kit Portable

Light and Durable

  • Modern vehicles have over 30 body control modules. All of these units consume power from the vehicle's battery, albeit in small but constant amounts. This is why after 1-2 weeks of non-use the vehicle's battery is drained and will not start.
  • But when you have OYMSAE's 20W solar battery trickle charger, it will protect your battery power throughout the season, and it will continuously deliver power to your 12V battery as long as there is sunlight, extending your battery's life.
  • Equipped with monocrystalline silicon solar chip, the photoelectric conversion efficiency is increased by 10-20%!
  • Use PET panel material, 1-2 times more sunlight refraction absorption than other solar panels!
  • Built-in 2022 models to upgrade the controller, no power consumption at night! Overcharge protection, overvoltage protection, anti-reverse charge protection, short circuit protection!
  • Visual LED indicator, so you are always clear about the current state of charge! Plug-and-play SAE extension cable, equipped with all kinds of adapter extension cable, easy to connect and disconnect!
  • IP67 waterproof rating, perfect for outdoor work!

3 Reasons to Choose OYMSAE

How to Clear The Indicator Status

  • Blue light is on to indicate that it has received sunlight.
  • While the blue light is on, the solar panel is connected to the battery and the red light is on, indicating that it is charging.
  • When the battery is fully charged, the green light will come on, at which time all three color LEDs will light up, indicating that charging is complete.
  • There is also a special case: the LEDs are all off, indicating a short circuit has occurred. You need to check whether your polarity connection is wrong.

IP67 Waterproof

  • If you need solar panels on a boat or other places. What should I do if it rains or snows?
  • Fortunately, what you have is a waterproof solar panel. You can relax.
  • IP67 waterproof can protect it from rain and snow, even if you forget to store it, you don't have to fear that it has been damaged.
  • What you need to pay attention to is that you need to place the solar panel at an angle, and not allow the controller on the back of the panel to be submerged in water for a long time.

Strong & Durable

  • The broken solar panel will cause the efficiency of charging to drop. It is really terrible.
  • But different from other products, we added a layer of PCB as the bottom plate. An extra layer of bottom plate will make this solar panel stronger.
  • Using thicker wires will make it more durable.

How to Use Accessories

  • The O-ring cable can be connected to the car battery for a long time.If you do not need frequent disassembly and connection, you can choose this method.
  • The alligator clip cable is used to quickly connect the battery. It is not recommended to use it while the car is driving, it may cause a short circuit due to looseness.
  • The cigarette lighter cable is used to connect to a power outlet. Certain brands of cars do not have electricity after they are turned off, it can‘t be used normally. It is recommended to use alligator clips or O-rings for connection.
  • The suction cups can be installed forwards and backwards for fixing inside and outside of the car glass.
