Systems on a 10-metre sailing boat

Hi everyone!

I’d like to upgrade my boat with a solar system to charge the batteries. At the moment, it has two 80 Ah lead-acid batteries:

one for the engine and one for the onboard services. There’s a diode bridge between the two batteries.

I have a 220 V battery charger connected to the services battery, so it doesn’t charge the

engine battery when I’m moored in the marina.

Can anyone help me figure out what to install to charge both batteries using the solar panels I’m going to fit on the boat’s roof?

Thanks, everyone.

You can use a charger with two outputs, or a MultiPlus and connect its auxiliary charging output to the starter battery.
