It seems motors like those on winches and windlasses, electrics toilets and the like are things like a specific voltage.

And here I thought 24V was mostly for the bigger boats and it requires specific and more expensive electronics to work. So a quick look at the market leader, Raymarine: their MFD can use 24V, but all the latest VHF radios they sell are 9-16V:


VHF Radio Communications | Raymarine


Oh, spoke too soon, their latest MFD for the cruiser market is also 12V only:


NEW AXIOM 7 | Raymarine by FLIR


Maybe it's just Raymarine? Try B&G then. Ok, again, no dice there, the Vulcan series takes 10-17V:

How about the Zeus chartplotter series? Yay! Finally we found another device that takes up to 31V DC.


So, no, I wasn't mistaken that 24V marine electronics are harder to come by.

they dont need much juice, can be operated by a step-down converter. More critical are all pumps an winches, windlass, hydraulc pump for the auto pilot and other heavy duty stuff...

It is PITA to change everything on board to 24V, every relay, every bulb, LED lights, switch with an indicator LED or bulb, solenoid, electric valve, electric head, ventillator ...

Easiest and most straight forward would be to sell the inverter, buy a 12V inverter (e.g Victron 12/5000) and wire the LFP to a 12V configuration. That is what I would do if the vessel is not genuine 24V.
