Mike - thats not a hissy fit. It sounds like you have a
solar controller that can be used for both 12 and 24V. The battery must be connected to the regulator before you connect the
solar panels, so it senses the correct the voltage of your system. In your case, the hissy fit is the regulator thinking you've got 24V.
If you ever disconnect your batteries or you use a switch to turn them off, you must also disconnect the panels. Then when you reconnect, you must connect the panels last.
