Adding another MPPT controller

I am adding more pv panels, and my present 20 amp MPPT controller will not be adequate. Will a second 20 amp MPPT controller wired in parallel to existing set up be OK, or will they interfere with each other? . Would it be better to route all the pv panels through a new 40 amp controller?

Do you have a Venus device? Are you running ESS?

Are they SmartSolar or BlueSolar?
