I am in exactly the same position as you....in the summer we run the genny up to several hours a day, at anchor, but in the winter we are on shore power and the battery goes down. The FP control unit takes a little current and there is the self-discharge of the battery. For the longest life, you want to keep your battery at about 13.5V float charged 24/7.

My domestic system is 24 volt, so I cannot join them to the generator battery.
[/ QUOTE ]Yes, you can, as long as the 'neutrals' - negative terminals - are normally connected anyway. We would simply agree a fixed float charge current - probably 50 mA to start with - and adjust later with another resistor in parallel if needed. That has to be the cheapest and most effective long-term solution for you.
You would need a different resistor value. If you are interested I'll calculate the value and power you need.
