The MPPT controllers certainly assist with the optimisation, I just think the output is a lot less than perceived, hence why my panel area and watt output is high for the 6amp load- intermittent - from the 60L engel.
Happy to stand corrected, but from a marketing perspective, there isn't a marketing guy out there that will sell something based on real numbers, more on the maximum possible, even if its unachievable.
