Does anyone use a 24 volt house system on a boat with a 12 volt starter/engine system?
I'm thinking of how I would like to set my boat up when i get one and am interested on others peoples thoughts.
For a ~ 5kw victron Quattro system I think 24 volt house battery
would be greatly prefered for current
draw reasons from the battery
. A ~ 5KW generator
should be able to keep it charged when required.
If I stayed with a standard 12 volt system on the Yanmars, there would need to be many additional parts
required to get charge from the alternator
to the house batteries. More complexity, more things that can go wrong.
Perhaps an easier way would be a 24 volt alternator
, and a step down to 12 volt to charge the starting batteries, and a 24 volt centerfielder.
Thirdly, a second alternator on the yanmar
rated at 24 volts?
Or finally, would I be better to just use a 12 volt Victron Quattro and use twin, short, large battery leads to minimise voltage drop under heavy load?
I would like to keep the starter system independent of the Quattro for redundancy reasons.
It will be a lifepo4
