I have a BigBlue CellPowa 500 power station which I use in the car for day trips or camping. I usually just have a small refrigerator connected to it to keep the food and drinks cold in the summer. The power station has a built-in ability to charge via a solar panel so I would like to install one 100W panel on the roof of my car. Now, according to the manual, there is MPPT controller built in so I assume I could connect the solar panel directly to the power station, correct? But the manual also states that the power station supports 12-30V 4A (110W max) and they want the user to disconnect the solar panel once the battery is fully charged. So here is the question: Is there a way I could come up with a system using the power station and one solar panel (with or without any additional hardware/electronics) that would allow me to keep the power station in the car and constantly connected to the solar panel? I do not really want a system that will require manual intervention (turning on or off) depending on whether the battery is charged or not.
