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
