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

How to charge 2 separated batteries with only one MPPT ?
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
Hi Matthias.
Thanks for your feed back, but I think that it is not a good solution since the MPPT is done to check permanently and precisely the voltage of the battery to be loaded. With the diode it is not possible and the battery won't be charged correctly.
The ArgoDiode documentation says that it is to be used with the alternator, not with a MPPT (and for that, the RagoFET is better than the ArgoDiode)
I think that the best solution would be to have a switch wich could switch automaticaly from one battery to the other one (when one is full loaded for example)
