Previous page Next page OK 12v solar system charge multiple batteries simultaneously? Yes, It is ok connect multiple batteries in series and parallel .Keep the combined battery voltage will always at 12v. Either connect two 6v batteries in series or parallel multiple 12v batteries. When the controller stop charging the battery ? 12v battery ,the controller will stop charging when indicating that the battery is fully charged .When the battery drops to a maintainable level ,the controller will resume charging. Why test voltage over 20V ? The 20v is the open-circle voltage of the solar panel ,not the charging voltage .Test voltage ensure that the solar panel system remains connected to the battery . Overcharge protect my batteries? The built in controller includes overcharge protection .
Higher Efficiency：PET has regular bumps on the surface. It forms secondary light transmission, absorb a lot of solar energy, and the photoelectric conversion efficiency is as high as 95%
Charging Visualization：The indicator lights of the solar charger help you better distinguish the usage status of the solar charger
Intelligent Protection：The solar panel has a built-in microprocessor. It provides multiple protections. It prevents reverse charging, and it is safely used for charging and maintaining 12V batteries
The package includes a three-piece SAE cable kit, plug, and play. Combiners and suction cups meet different installation needs. Suitable for cars, RVs, motorcycles, ships, snowmobiles, etc
More Durable：PET is waterproof and dust-proof. The PCB is used as the bottom plate, which is stronger and not easily broken (a broken panel will reduce the charging efficiency). If you have any questions, Feel free to contact us at any time
