[QUOTE="binky, post: 545600, member: 490"] so the limiting factor is the inverter, it's designed to run at 3.6kW and you have nearly 5kW of panels attached to it, you won't hit 4.9kw except as an odd spike. I suspect what is happening is that the inverter is making itself less efficient to cope with high output from the panels, effectively cutting output. The upside of having a set of panels larger than the inverter is improved winter output, but personally, I gave up undersizing inverters years ago. Undersizing is taught as acceptable practice on solar design courses, but they are a little out of date as inverter efficieny has vastly improved over the last decade [/QUOTE]
