Re: [Amel Yacht Owners] Re: Inverter Replacement



Your email didn't survive encoding by Yahoo, so I'll answer here...

I installed the Multiplus in the engine room, using the existing cables from the old charger that it replaced, although I did add an appropriately sized fuse. The Multiplus case ground is connected to the safety ground of the 220V system.  There is no connection between the DC negative and the case of the unit.

The AC system on Harmonie is a good deal more complex than on most SMs. Its current schematic can be seen here: 

The original owners apparently insisted that AMEL install a fully functional 110V system in parallel with the 220V system. So Harmonie has 110V outlets in every cabin, two shore power cables, one for 110, and one for 220, a 110V --> 220V transformer, a 110V inverter/charger, and a 220V inverter/charger, and an additional 50 amp 220V battery charger.  We never use the 110 charger since we added the Victron, it does all the heavy lifting.

A bit of a jumble, but everybody plays happy with only minimal manual intervention, and when plugged into 110 shore power, I am comfortable that I get safe and effective 220V power AND 110V.

Hi Bill

On Island Pearl II we installed the sister unit to yours, ie. a Victron MultiPlus 24v/3000w/70amp inverter/charger and we are extremely happy with it. Our two Dophin 30 and 50 chargers are still working fine, but only there for back up now as the Victron is so much faster and efficient.

Rather than bore everyone here perhaps on this specific question, perhaps you could email me directly on colin.cruisingpoint@.... I am particularly keen to know how you connected your system up?. In my case I placed this unit on the RHS of the navstation so that it is right up close to the batteries with good oversized cable going directly through the battery cavity wall (appropriately sealed off of course) , and the shore power now comes in directly to this unit, through it, and then into the normal AC system control panel.

I am particularly interested to know if/where you ran the ground cable which attached onto the outside shell/steel case of the unit?
