MX60 @ 72 volts

I have 3 KC 130 12v 21.9 voc 7.4 amps
       3 GE 110 12v 21.2 voc 6.6 amps
       2 GE 100 12v 20.6 voc 6.2 amps.

The MX60 specs say I can Series up to 72 volts.
 
Can I series the 3 KC 130's & the 3 GE 110's for 72 volts to the MX60 & then run the 2 GE 100's thru my Xantrex c60 in paralell with the 6 130/110's.
 
My total array will be 720 watts on the MX60 with 129.3 voc
& 200 watts on the C60 for a total of 920 watts.

If this is ok what amperage would the MX 60 use for the 6 panels?

All panels are 12 volt,
batteries are 3 Rolls 4 KS 25PS 1350 AH @ 20

Regards

Re: MX60 @ 72 volts

i would not do that.


 the ge should go together, not the mix of the wildly different mono ge and poly kyocera.

assuming the worst case, -5 to - 40 F coldest temps where you live, the 5 ge modules in series still works on the mx 60.

put the kyoceras on another controller, if you are not going to expand, i'd pick a morningstar prostar 30m.  if you are going to expand, look into another mppt controller, or bump up to a tristar from morningstar.

that's my two cents
