I need to build a three phase system (ESS). Can I use three of the Multiplus II GX units, or is only one GX allowed and the other two MUST be only Multiplus II units? Can I not set the one GX unit as master and the other two GX units will operate with their GX disabled?
You probably can, but where is economical sens of doing it this way?
MP-II GX is more expensive than plain MP-II
Thank you for the quick confirmation.
No it is not economical, other than immediate product availability, and the client looking for a solution a.s.a.p
Product availability can be a great motivator. :)
I can relate to that.
I am finishing my 3-phase system build on 2 MultiPlus-II and 1 EasySolar-II GX.
Did not plan to buy EasySolar-II GX but MultiPlus -II GX was not available. :)
Now I am trying to find application for MPPT 250/70 that came with EasySolar.
Probably will buy more solar panels.
In your case, you will probably have to physically disconnect those not needed GXs.
Yes, what you say agrees with this:

I just disconnected two of them now, and will see how the installation goes this week.
Thanks again for the confirmation.
