Using Hub D1 and Solar 4K at the same time

Is there a new hub in the works to make this possible? I was thinking of rigging up a junction box to try it out.

@Kipper
Hub D1 is essentially an external DC multi-output port for the Apex 300, while the SolarX 4K is a PV step-down module. Both can certainly be used simultaneously with the Apex 300. :)

They both plug into the battery expansion port. There is only one of those. How is it possible to use both at the same time?

@Kipper I apologize, but upon confirmation, it has been confirmed that the Hub D1 and SolarX 4K cannot be used on a single Apex 300. They can only be used simultaneously on two parallel Apex 300 units.
