Hi, i bought a solar panel along with a charge controller to charge a 12V car battery. The battery will basically always have a small load, occasionally driving a bigger load. What i was wondering was whether the solar panel needs to be physically disconnected while there is a load.
During a higher load (400W), will my small 20W solar panel get damaged? I dont know much about whether they have a shutoff when the leads are short-circuited, or if its ok to short circuit their leads. I don't know if charge controllers can sense whether the battery is driving a load, or even if its possible for them to know. I quickly drew up a rough schematic for this situation. Thanks
