Overview:
In simple terms, MPPT (Maximum Power Point Tracking) mode determines how the solar panels connected to a device extract power from the sun.
Independent MPPT:
- Each solar panel input tracks its own maximum power point independently.
- This is useful when the panels are facing different directions or have different levels of shade.
Parallel MPPT:
- Both solar panel inputs are combined so they track the same maximum power point.
- This is ideal when all panels are facing the same direction and have similar levels of shade.
- Parallel MPPT mode is slightly more efficient overall compared to Independent MPPT.
Summary
In summary, if your solar panels are all facing the same way and have consistent conditions, choose Parallel MPPT for higher efficiency. If your panels face different directions or have varying shade levels, Independent MPPT is the better option for optimized power extraction
