Solar charge controllers use the battery bank to provide a reference voltage for operation. For this reason **the battery should always be present when solar panels are connected**. This suggests a particular order for connection/disconnection/resetting: | Solar charge controllers use the battery bank to provide a reference voltage for operation.

> The reason for the low side switching is the intersection between physics and economics. N-channel field effect transistors are faster, better, cheaper than P-channel parts. The designer can A) use good parts in a simple circuit or B) use more expensive not so good parts or C) make a complicated circuit that uses 18 volts to control a 15 volt switch.((http://www.cheaprvliving.com/forums/showthread.php?tid=24605&pid=307539#pid307539)) | > The reason for the low side switching is the intersection between physics and economics.
