Arduino solar charge controller

Posted on Tuesday, October 22nd, 2013 in Arduino, hacks by DP

In this video Julian Ilett demonstrates his Arduino solar charge controller:

High efficiency values (96% – 97%) are achievable when the buck converter is stepping down from 18v to 12v. With a 72-cell panel and the converter stepping 35v down to 12v, the efficiency drops to around 88%.

    Well we know his PWM frequency is about 15KHz, and his camera’s mic picks that up quite happily!

    Ow. Now I’m looking for audio EQ software.. (OOoh, this Equalizer APO looks good.)

    Other than that, it’s a really fascinating build; I love the “mo’ display, mo’ data” scheme with the little Nokia LCD, and the free-air construction technique is fascinating.

    Why hook up extra solar panels in series, instead of parallel?

    Brilliant build by the way! Well done.
