I've been running two arrays into two charge controllers at 24 volts into one battery bank.
These are have been located on two different buildings.

One has Matrix and Evergreens at Vp 17.4, Voc 21.7, totaling about 1000 watts, going into an Outback mx60.

The other is a "democracy rack" mostly of old SMUDs, quads and tris at Vp 17, Voc 20, totaling about 500 watts.
I did have 8 Siemans M75's, Vp 15.9, Voc 19.8, 400 watts hooked up with these SMUD's. Total of this array was 900 watts
This array goes into a Solar Boost 50 MPPT.

I am changing my 2nd location and moving these near the first array. I can hook the Sieman's up to either array.

Which would be the most efficient.

Thanks in advance. What a wonderful forum.
