I think each unit needs to be set at 17A, but the cerbo also needs to know the combined current max - for the battery max charge current. Limiting the MPT's to 17A is probably not needed with the Cerbo monitoring the max battery current. Doing so will prevent them from serving other dc loads (inverter etc) while still charging the battery to 37A.

seems a low max current for a battery though.
