20x400w Or 22x400w, Solis 6kW hybrid inverter, South facing roof - System limitations

    Solar system on the way for the house, should be end of Feb/March install, Looking at 20x400w panels on a directly south facing roof

    Question is - The inverter is a Solis RHI-6K-48ES-5G 6kW Hybrid and i think it is capable of taking an extra 2 panels (one per string), Is it worth putting up the extra two panels during install, i realise even with the 20 panels i will get clipping during the good weather, but when the weather is not so good i assume the more panels the better.

    Is it taxing on the inverter to have that amount of panels when weather is optimal?, what are the limiting factors? is there a max voltage per string and how would i work that out?

    Loads of questions !! 🙂
