Tail current adjusted to 2%.👍🏻 ---

I used 2x 10 qm parallel to the MPPT controler. It were 6 x 205wp panels. As fuses I used car fuses (which was a bad choice, as the fusebox interior gradually dissolved in the chemicals we loaded). In the end I skipped the fuses altogether and used a 6x MC4 splitter. ---

My go to idea is always higher voltage means smaller cable cross section lower amps, better power transfer. Less losses. Smaller fuses. ---

Everything has plus and minus sometimes you lose sometimes you win. This is an issue in a stationary solar farm you can live with. Lastly having several strings on the same MPPT you still encounter a similar issue… Right? ---

… I’m totally with you on that when you look at this roof … ![Her EV](https://europe1.discourse-cdn.com/victron/original/2X/0/09c9bf0e13e85edd334100909db9825c2d1714ff.jpeg) Is it really difficult here with a parallel arrangement … The issue is achieving max Voltage as early as possible … so in series ---

Good explanation, just to add, the main trade-off is efficiency vs safety. Series strings are more efficient but need careful voltage management, while 2S2P is more stable and shading-friendly but requires heavier wiring.
