Solar panel connected with a Dc to DC charger

Hi

I have a DC to DC charger (non isolated) I also bought a solar panel and MPPT 75 solar controller. Is there anyway I can wire these together. When my truck is turned off the solar takes control and when I'm driving the Dc to DC takes control.

Thank you in advance

Generally, you can simply connect the output of both the DC-DC and MPPT to the battery. If the combined output of both charging sources does not exceed the battery's maximum charging current then they can both run simultaneously.

Shouldn't i put a blocking diode to protect the solar panels to avoid the dcdc sends reverse current to the panels when light Intensity is low?
