I am merely a solar bozo. One correction, I think it "shares" current from the second 12 V tap, not the 24 V tap.
I do not know if the equipment is capable of an equalizing scheme whereby it can tap 12 V and 24 V off the same 48 V string (per the original question in this thread), but a quick call to Vanner would provide answers.
