When my solar panels are sitting in the sun all day but the battery is full, where does the extra power go?

Question

Edit: I should mention it’s a boat system so it’s not grid tied

Answer 1

Well hopefully you have a charge controller/conditioner connected to it, or else the power is going to keep going into your batteries and “boil” them, and that’s not a fun time.

Please tell me you have a charge controller.
