Hello Mick,

I suspect your low reading was due mostly to the angle of the sun on your panels. If your roof angle is shallow or your roof is a long way from due south then you wouldn’t get that close to the maximum. It is now almost mid summer. Has your reading improved? My system is a 3.84 kw system and it regularly reads 4 kw in April and September when the weather isn’t particularly hot and the sun is at about 90 degrees to my panels (My roof is 55 degrees from the horizontal)
