    28x2 MPPT Success, 50v 35amp ,2.1Kw Panels

    Hi I have been ably to get to picaxe to communicate with the Pi, the driver listed worked for me. I had to follow the extra instructions when installing the driver, but it worked. I don't program the picaxe with the Pi I use it to get serial data to a data base.

    28x2 MPPT Success, 50v 35amp ,2.1Kw Panels

    Hi ferando Thanks for that info. I have been using a manual input to adjust the pwm, record the highest and then let it run and compare. I've been very happy with the results. PWM@100khz and voltage/amps sampling at 20 Hz the response is nice and quick under 1 second.

    08M2 PV MPPT Charge Controller

    Hi All, I have just built a MPPT for my 2.1Kw solar array. I use the system to power my HotWater. The Picaxe 28x2 does the job very well, returns 95% to 85% efficency, very pleasing result, as this was my first design project. To answer the question can a Picaxe chip run an MPPT for me it is YES.
