Hi,
Seeing the dual output alternator posts has just made me wonder if anybody
here might be able to help me. I'm restoring a dutch barge on which the
majority of the systems will be 24v, but, I've been given a Victron 2kVA
uninterruptable power supply which needs extra batteries grafted on at 48V.
Has anybody got any ideas on how best to combine a 24 and 48v systems? I'd
pondered whether it was possible, with 4 12v batteries in series (to give
the 48v, which will be charged by the ups) to take 2 24V taps from them?

You should be able to do this with a relay or two and possibly a timer
that will allow charging at 24v and use at 48v. Albright International
make seriously heavy duty relays at very resaonable cost.

Renovation project still available. - 37 ft steel twin screw, built 1960 by Thames and General at Brentford, for their MD. Hull plating done 6 years ago, but more work needed. Looks like the 42 foot Sealion, excellent sea boat, but displacement hull, so only 8 - 8.5 knots. Even a suggestio...
