So a little bit out of order today because the weather has been so nice recently, but I have installed about 1/4 of my panels. After experimenting with different configurations, it turns out my inverter likes DC voltages above 180 vols, I have decided to configure my system with 4 strings of 6 panels. 6 panels in series and 4 strings in parallel. Today was a cloudy day and I wired up the first string and the 240 volt line to the inverter. The results so far are good. My Zero Export configuration is working and for a short time today I was able to 100% power my home with solar! I had a peak output of 780 watts.
