    Opinion on system

    So I think I have found a good system for a great price. Please critique system as a whole or individual pieces. Thanks!

    2 x Schneider Conext XW+ 5500 Watt 48volt
    1 x Schneider System control panel
    1 x Schneider XW+ Power dist. panel 250 Amp
    36 x Kyocera 265 Watt 31 Volts 8.55 Amps
    Context 60 Amp MPPT Charge controller.
    8 x Concorde Sun xtender 6V AGM 405 Ah Wired at 48 volt.

    Plus all other parts for install. What you think guys?

    I haven't reviewed your other posts for information about the loads you want to support, but off the cuff, it looks like too many panels. The Conext 60 can take 6720 W of panels (140 Voc * 48 A) input, but even then, the max output is 3500 W. 36 *265 = 9540 W, which might produce almost 200 A if you had more / bigger charge controllers. C/4 charge current on a 400 Ah battery is 100 A... you'd be looking at C/2 with that array (if you added more CC capacity). Without more CC capacity, 60 A charge current is not enough to take care of your 400 Ah very nice batteries... I think you'd need at least 80 A (C/5) for these.

    Did I misunderstand something?
