OYMSAE 20W Solar Panel Kit Solar Battery Maintainer & Trickle Charger

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.

 Note 

  • 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.

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.
  • 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.
