How to charge 2 separated batteries with only one MPPT ?

I have two battery parks, one for the engine and one for services.

The services park is charged with one Solar Pannel through a MPPT 75/15, but this regulator has only one output.

How should I do to also charge the engine park ?

Thanks a lot

A few weeks ago I used an ArgoDiode to split the output of the MPPT.

0,3V drop...

Never convinced me working with diodes in this case.

Solenoids are a solid solution. Should be named "Solidnoids" hehe
