My last system, I went with Solaredge so the oversized 1.1 ratios DC didn't concern me one bit since I have a West-East layout. With experience, I would be comfortable up to 1.25 without much clipping.
Now I am installing a second system in San Diego East with plenty of sun exposure at 145 Azimuth (South-East) with Micro inverters I am a bit concerned.
I ran all the calculations through PVwatts and it is showing just 3kwh difference due to 1.2 DC ratio compared to 1.0 ratio. The iQ6+ 280W continuous is available but obviously will cost more. I'm trying to stay with the lowest cost option as long as it's not a "stupid" move.
I will be running this small 2kw system without the Envoy monitor. My only tool monitoring tool is a basic in-line watt meter.
