Running 2 different MPPT controllers

I have a PV array connected to a Outback 80amp MPPT controller. I also have a Victron 150/35 BlueSolar controller and panels that I would like to add to the system. Is this possible, mixing MPPT controllers of differnet brands? If not I would change the Outback unit to a Victron 150/100 MPPT.


Also, are there any schematics on how to wire them together.


Thanks for any information.

Hi Nathan. Yes you can do that.

I've extracted this schematic from the Victron Van Install. There's other kit installed there which complicates following the wiring, but essentially they're just paralleled in to the same batts/bus. Just substitute one of the Victrons with your FM80.

Of course the comms aren't compatible, but they'll work functionally alongside each other.
