^4 was never built since the LT3652 solar charger control was found not to be needed when charging a 12V SLA with a 3 watt 36 cell solar panel. ^5 is only a schematic (atm) but it shows ideas from RPUlux that have worked on the bench. An alternate power input that can be enabled with the controller when the battery can accept a charge from a solar panel. It is a DIY option and using it has a risk, for example, if the program running on the controller stops or crashes the battery will end up damaged (the LT3652 did not have that issue).
