Yes you were right Gimzo about the heat it produced, I put a temp gun on it this morning before it got even close to it's full output from the solar panels and measured 73 degrees C, so quickly this morning had an old CPU heatsink and fan and modified it to suit what I had built, testing times still ahead, I did notice that I have a problem with resistor value, as it locks itself on and will not disengaged with powering down the 12v supply
