SUNAPEX Flexible Solar Panel Kit For 12V Battery Maintain & Trickle Charging Why Do We Need a Solar Trickle Charger or Battery Maintainer? 1. Natural Battery Discharge --- Ever left your car sitting for a while only to find a dead battery when you need it most? This is because the car battery will continue to discharge naturally even if the car is parked. Our solar battery charger prevents this by constantly topping up your battery, ensuring it's ready to roll whenever you are. 2. Continuous Power Drain --- Today's vehicles are packed with over 30 electronics - control modules, alarms, anti-theft systems, and more. They all consume your battery power even when parked. With our solar panel charger, you'll combat this power drain, guaranteeing your car is always ready for action. 3. Extend Battery Life --- Your car battery's lifespan depends on maintaining the right voltage. If a 12V battery dips too low can lead to sulfation, which is the main leading cause of battery failure. Our solar car charger keeps your battery voltage in the sweet spot, prolonging its life and saving you the cost of a replacement. How to Choose the Right Solar Panel for Your Car? 1. Battery Condition --- First of all, our solar panels are only suitable for trickle charging and maintaining 12V batteries, not suitable for batteries already dead. Please check your battery condition before using this solar trickle charger, if the use of the car battery is too long or aging, then even if the solar panel is charged, the battery may not be fully charged or the charging state may not be kept. 2. Power Output --- The larger the power of the solar panel, the faster the charging speed. If the solar panel's power is not enough to meet the needs of the car battery, the battery may not be fully charged even if it is exposed to sunlight all day. So please choose the right watts to match your battery. 3. Usage --- If you use your car daily, a lower wattage panel may suffice to maintain your battery. For vehicles parked for extended periods, higher wattage panels (20W and above) provide better effect against battery drain. 30W is ideal for larger vehicles, like SUVs or RVs, or if you have several power-hungry devices to charge. ✅【High-Efficiency Charging】SUNAPEX 10W solar battery charger is made of more effective monocrystalline silicon material, which absorbs solar radiation heat to a greater extent.

Thank you for supporting and choosing VOLTSET. ------------------------------------------------------------------------------------------------------------------------------------------------------------- 20W Solar Panel Kit For 12V Battery Maintenance & Trickle Charging Why We Need a Solar Trickle Charger or Battery Maintainer Batteries consume power slowly and car batteries will discharge automatically when the car is not used for a long time If the battery is completely depleted, even if it is fully charged again, the maximum capacity of the battery will be reduced 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. Upgraded 100% Waterproof 10A Charger Controller The upgraded 10A MPPT charge controller is 25%-30% more efficient than conventional controllers. The controller adopts a fully glued design to avoid the possibility of water intrusion and moisture in rainy and snowy days as much as possible. High Conversion Rate - the conversion rate of monocrystal can reach 30%, while polycrystalline is only 15%. Trickle & Maintain - makes up for the capacity loss caused by self-discharge after the battery is fully charged; beneficial to 12v battery maintenance and extending the life of the battery. 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 tempered solar glass which is different from others to achieve more than 2 times of solar light reabsorption, further improving the solar energy absorption efficiency. The solar car charger is made of high-quality monocrystalline silicon material, which is impact-resistant, wind-snow-resistant, corrosion-resistant, and can adapt to any bad weather.
