Adding MPPT on existing installation

Hi all,

I need an advice. Browsing the forum I have found installation similar the on I have. And on this installation I would like to add an solar charging also.

I is possible to charge all of battery packs and what would be the connection point?

Considering it is a small boat and I can accommodate only two smaller panels like 95w mono.

If you charge the starter battery with the solar then the Orions will charge your other 2 batteries. Many people do it this way. You may need to confirm the solar is increasing the battery voltage enough to trigger the engine start up settings on the Orions. The Orions should limit charge current to what is available. The only thing to watch for is one of the Orions may take the charge current preferentialy because you will have a low current and both will be trying to control the input voltage.
