The main function of this product is to charge the 18V battery of car,moto and motorboat or most of the 12V lead-acid and lithium batteries.The trickle charging will be helpful for extending the battery life though its current is small.The charging method is not only energy saving,maintain battery life,but also can meet the needs of some small capacity car audios,which it's very suitable for outdoor work,travel or camping.
About ETFE Solar Panel:
ETFE solar panels have strong oxidation resistance and the longest service life. When people do this, the price is relatively expensive. If you want to put solar panels on the seaside or some places with heavy salt fog,we suggest you choose ETFE monocrystalline solar panels.

1*300W Solar Panel
We will give you the corresponding controller according to the total wattage of the solar panel you purchased.
Regarding the delivery of the controller:
1. We will give a free controller when purchasing solar panels.
2. The solar panel and the controller are shipped together, which will increase our logistics cost. Therefore, the gift controller and solar panel are shipped separately. The controller will be shipped with different logistics, generally within 1-5 days after receiving the solar panel, the controller will be received.
3. If you have not received the controller, please contact us.
Tip：The controller will only be given when shipped from China, and the controller will not be given when shipped from other warehouses (Czech warehouse, Spanish warehouse), please buy it yourself.
About the controller:
1.The solar system kit connection is divided into parallel connection or serial connection. The controller must be first connect the battery , and then connect the solar panels.
2.When the solar panels are connected in series or in parallel, paid to the highest PV input voltage of the controller. The voltage connected in parallel to the controller after the series connection cannot exceed the maximum input voltage of the controller.
3.The total input power of the solar panel can't be greater than the rated power of the controller, otherwise, there is a risk of burning the controller.
4.When the power rating of one controller is insufficient to meet all solar panels, multiple controllers can be simultaneously connected to the battery.
