So,i'm going to be adding another array this summer, enlarging my battery bank and since I already have a Tristar MPPT controller, I'm considering getting another one. So putting 2 controllers on one bank generally works, one just lags the other.

To sync the controllers, so they can both charge, instead of one thinking it's hit float first, does the morningstar meter hub slave 2 charge controllers together, or is it only for meter reading ease ?

    No slaving, just the ability for a single meter to monitor both chargers and have other devices like a relay module interconnected

    Any known way for the 2 MPPT's to share the same "brain" so they work together, instead as 2? I think I've discovered a flaw in my scheme to rule the world :cry:

    Julie - does your sw do any control management of the MS MPPT's ?

    Plug one RJ-45 in the CC connector and the other one in a CC connector. You can even plug the next RJ 45 into your inverter/charger. Oh yea, you don't have xw cc's... That extra one or two percent of efficiency is really not worth it offgrid when you lose the ability to network multiple cc's. Having all that data on the SCP. I don't get it Mike.
