Using mini ultra plus with solar panel

[brooksdr]

How do I use the mini ultra plus with a 6- or 12-V solar panel providing the power. I understand this board includes a MPPT circuit for charging a LiPo battery, but how do I power the board/charger with a solar panel??

Hi Brook,
The input to the charger power management is best pair with a 6V 3W (or higher W) solar panel by connecting it to VIN (DC barrel jack). 6V rated solar panel will provide an input voltage (after diode drop voltage) as close to optimum voltage to the charger. If the sunlight drops, the charger will reduce the current accordingly to prevent the input voltage from collapsing totally.
