Again, thanks for the feedback. A LOT easier to make fixes now than once installed. :facepalm:

Re: New Victron Multiplus install with Li Batteries

On a couple of manufacturers sites, I've specifically seen two shore power inlets combined into one Galvanic Isolator. The just purchased ProMariner, 22074 ProSafe FS 60 Galvanic Isolator...

Re: New Victron Multiplus install with Li Batteries

Updated the schematic to reflect a change in plans, 'moving' the house batteries to where the current batteries are located in the rear berth. Will put the Victron Multiplus Inverter/Charger where...

Re: New Victron Multiplus install with Li Batteries

Everything is a trade-off. Went to the boat (up on the hard) and did a bunch of measuring and sitting, thinking about the install.

The boat only has a single rear starboard cabin with a huge port...

Re: New Victron Multiplus install with Li Batteries

The Victron Service Manual:



What I think all of that means is that PowerAssist is not directly available to AC-out-2, so the 25A limit while connected to shore power is inviolable. But,...

Re: New Victron Multiplus install with Li Batteries

MerMike, have been doing the research on the ELCI requirement. I will admit I did not realize this was an ABYC requirement for new boats. Again, not an electrical expert so trying to figure this out....

Re: New Victron Multiplus install with Li Batteries

Not to worry... spend half my time on conference calls thinking "why oh why did I sleep through those EE classes?" :smile:

Re: New Victron Multiplus install with Li Batteries

Your statement makes sense. For my current needs, it's not an issue for me. Being berthed in a marina on the Chesapeake and going out for 2-3 day sails, with shore power available at pretty much all...

Re: New Victron Multiplus install with Li Batteries

On second thought, I'm updating the PowerPoint deck, so many details can be added. Not really possible with pdf editors (at least not easily). Will post the Powerpoint updates along the way.

Re: New Victron Multiplus install with Li Batteries

Good old Adobe Acrobat Pro. No way I would do it from scratch. What I do is modify the Victron pdfs. Very tedious but I work on it during conference calls... beats doodling. Also calms me down,...

Re: New Victron Multiplus install with Li Batteries

If you download the pdf, it will scale up and the text is readable.

I'm glad you asked for these, as they are very important and give the sizing requirements and call out the need for MCB/RDC...

Re: New Victron Multiplus install with Li Batteries

Took another stab at the electrical diagram, beginning with a Victron schematic and modifying to come close to what I'm going to do. I'll have 3 DC-DC chargers and the CERBO GC wiring isn't correct....

Re: New Victron Multiplus install with Li Batteries

Attached 3 options for the battery cabling layout with fusing. Option 1 is my preference but am interested in input.

Re: New Victron Multiplus install with Li Batteries

Thanks for the responses. There is plenty of room to install a busbar to link each battery individually. The picture showing the batteries under the port seating does show how much room there is to...

Re: New Victron Multiplus install with Li Batteries

Here's a question which Battleborn hasn't answered.

If there are 3 100Ah batteries in the house bank, is it better to wire each battery, using equal length cables, to a busbar (3 connections to...

Re: Crewing as a female. Sketchy vs. Otherwise

Re: New Victron Multiplus install with Li Batteries

90% of the work in these projects is the up front planning.

Speaking with BattleBorn, they say the 300Ah bank will support the windlass/bow-thruster operation, especially if the engine is running....

Re: Beneteau rebuild turning into a nightmare

My understanding is they paid a lot more than I thought they had, so your comment is probably true. Plus this will always be a salvage boat, greatly reducing its resale value. That said, I've bought...
