After installing 2x6v batteries for 12v starting service
, and 8x6v as a 24v bank -and starting to run put of room! - I'm rethinking the need for yet another pair to serve as a 12v house bank.
We were planning to use a 24v to 12v DC converter Orion DC / DC Converters - Victron Energy
to support the 12v bank.......now I'm thinking of forgoing the 12v bank, and just running the 12 v load directly off the 24v bank via the converter.
It's not quite so crazy when you take the time to figure out the loads.....all our Garmin
nav system - radar
, sonar, chart plotter and autopilot
- can run off 24v. We need 12v to run the NEMA 2000 network, the VHF
, the small main sump bilge pump
and the SSB
- with the SSB
being the highest (30a) draw by far.
So.......what's the downside of running the 12v loads off a 40a DC to DC converter?
