I currently have a sonnenBatterie hybrid 9.53 with 8 x 385W Trina solar panels on one PV/MPP input and plan to add panels to that bank and then another smaller bank on the other MPP input. I've searched through the forums and haven't yet found an answer to my question which is; Is the Max. input voltage the total of both the MPP inputs? e.g. If I have one bank with 500v then one with 250v, then I'm up against the 750v max input voltage? I have the choice of two different brands of 415w panels. Brand A has a higher Voc of 50.1v and a lower Maximum Power Current-IMPP (A) of 9.86a while Brand B is 38.45v & 13.1A. If I max out the space available on my roof with brand A and my existing panels I get 766.4v total with both banks but less current. Brand B gets me 668v but the higher current. Any advice on which to run with?
Thanks.
The specs for the PV input side of things are as follows:
