Elmar Solar Maximum Power Point Tracker (MPPT)


A Maximum Power Point Tracker (MPPT) is used to maximize the energy delivered from a solar module array to a battery in varying light conditions.

The Race MPPT uses a boost converter circuit, comes with integrated maximum power point tracking algorithm and has li-ion charge capability. It can handle powers up to 1000W with a peak efficiency of over 99.3% while having a weight of only 395 gram.


Part of a family of MPPTs developed through years of competition and race tested in Solar Car events around the world.


Fully integrated into Profinity Software management solutions developed and used by experienced solar car racers.


Independently tested by Yokogawa to show MPPT optimizes the panel’s output voltage to maximize the amount of power generated by the solar panel array. Download report here.
