12V Solar Pannel Input and Output 12.8V for LFP battery pack.
I had two requirements for the MPPT charger:
1. Charging the battery, 12.8V, 12AH battery
2. If the battery is not connected, supply the 12.8V output to the system
Both the requirements are met by this module with IC CN3795
I recommend using it for similar or the same applications. The output voltage can be set by the divider network and MPPT threshold also.
