On the Victron SmartSolar MPPT 250/60-Tr there are 2x 2 MC4 connectors for two separate strings of solar panels. Can I use this MPPT in the situation I’ve panels on East and on West? Or should I use two separate MPPT chargers?

With panels on East and West they will never (of course) provide the same voltage/current so would East negatively influence the West solar generation and visa versa?

They are one tracker. Most ideally all panels face the same direction.

The mc4s are so current wise you are not causing a fire if you have parrallel strings (as mc4s have a current limit.)

Yes or a an mppt with multiple trackers like the mppt RS

Hi Rene,  
the two sets of mc4 connectors on the 250/60 tr are internally connected in parallel because the max Amp rating of a single mc4 is 30 Amps, so to get to the 60 Amp nameplate rating you would have to use 2 sets of mc4’s to handle the current.  
It is a single MPPT, meaning you would need another mppt to manage your east/west strings.

If you connect east and west to this single mppt, you will basically get the worst of both stings except the hours around noon.

Excellent feedback as well. Thanks for the fast response. @lxonline and @Stefan. I will go for two separate MPPT chargers.
