Hmm, interesting. I was thinking to just use a simple non isolated
Buck converter controlled by a PIC. This way I can simply add a
charging algorithm and other stuff too. MPPT is accomplished
by simply adjusting duty cycle for maximum charging current. This
way the input PV module operates at his Maximum Power Point.

It's a 24V 400AmpHour battery system.
