600W converter at MPPT (Maximum Power Point tracking)

This electronic converter integrating a microcontroller with a power of 600W is double function.

Beyond system monitoring, it performs an energy conversion to charge batteries. MPPT optimizes the energy efficiency from intermittent sources (hydro and solar inputs).

A configurable topology is undertaken with an H-bridge, which allows switching between bucking or boosting according to the available energy input.

Thanks to its intelligent charge control, taking into account the batteries state of charge (Absorption and Floating modes), the converter ensures multivoltage charging and the batteries integrity without the addition of an external regulator. Switching from one mode to another is automatic. RGB lighting indicates real-time charging power.
