Solar powered switch-mode charger (CN3801), protector (HY2112) and 5V booster (MT3608) for LiFePO4 batteries.
The charger provides maximum power point tracking (MPPT) and can easily be modified to work with LiPo batteries.
Arduino-run board that performs MPPT functionality on a power input to maximize power production for solar panels, wind generators and TEGs, and then regulates to 18V.
Input: 1-120VDC @ up to about 100W (10A max current regardless of voltage)
Output: 18VDC @ up to 10A (max 180W)
