Will the solar panel shut off once the batteries are charged and restart when they go down

Asked by: Aurtro Flores
As long as the charge controller is connected between the panel and battery, the Coleman 18 Watt 12V Solar Battery Charger Kit will regulate the charge taking place.

Will this unit charge two deep cycle batteries at the same time?

Asked by: Paul E L
Yes, as long as they're connected in parallel. Please note that this will take double the time that it would take to charge a single battery.

What is the charging amps? Will it charge an 80% depleted Marine battery in 24 hours?

Asked by: Charles22
The maximum amperage the solar panel can produce is 1.2 amps. You must ensure the battery's voltage is above 12, this will ensure that the charge controller recognizes the battery and allows the solar panel to charge the battery. The time it will take to charge battery is dependent on a number of factors,the weather and the storage capacity of your battery. Without this information it is impossible to determine how long the solar panel will take to charge the battery.

Can they be left out in the rain  water proof

Asked by: Ogbinpt
The Coleman 18 Watt 12V Solar Panel is waterproof, however the charge controller is not and must be protected from the elements.
