MPPT controller - voltage sensing without separate wires?

Soon to be released MPPT 3048 will have battery voltage sensing wires optional. Before they were standard. Now it is supposed to sense the battery voltage through main terminal cables, if I'm correct....

To be fair, previous 3024 was capable of at least 420W @12V. With rarely achievable peak, I would say the optimum wattage was 450-480W, but maximum 12V current was 30A anyway. The situation with voltage sense wires in similar units by bigger companies is the same as in this new 3048. Morningstar 45 has a terminal for sense wires, and says "not required but recommended". Blue Sky 30 - don't know. Both have 60V max voltage though, so can't be really considered "similar" now that 3048 has 100V max input.
