Thanks BentleyJ, and for the tip on where to also look for this kind of info (scoured the manual but didn't go back to datasheet). Jeff

In a 50 amp split phase Victron Multiplus II setup, I would like to use only one leg of the AC out 2. On the Multiplus AC Out 2 connection point, I will only connect wiring to L1 and Neutral and earth, and will not connect wire to L2. Sorry for what is probably silly question - is this the...

Thanks for feedback - when it was noisy during float charging, was that due to the fan noise? Any ambient 'hum' sound during normal operations - e.g., including when not charging or inverting? I'm guessing that I will just have to install the thing, use it under load and charge with it, to get...

I'm considering a Victron Multiplus II 2x120 for a 45 foot boat environment, but wondering if the fan / other noises from the unit would be too much for the small space? I've seen some reports of relatively high noise from this unit, and wondering if anyone has some real-world experiences...

Thank you Mike! I appreciate your (and everyone's) explanations. Just to make sure I understand, here is what I'm now planning: - moved Orion DCDC charger to be connected to starter battery - NOT to the Cristec isolator output - Orion DCDC charger would be enabled only with ignition ON, to...

RE the Amp-L-Start, I missed this from the web page: A new Ignition-Controlled Relay Kit is now available for use with all AMP-L-START™ revisions. It automatically inhibits operation of the AMP-L-START™ whenever your motorhome engine is running - Perfect for applications where a DC-DC power...

Hi Mike, I have a 150a one input/three output Cristec isolator: https://www.cristec.fr/english/our-products/battery-related-products/rce-electronic-battery-isolators/ My current house AGM bank is connected to the third isolator output. When I replace with Lithiums, was hoping to just connect...

Amp-L-Start looks neat - sort of a DCDC charger, but not charging/just passing current from one battery bank to another and acting as an isolator between them (a 'dumb' DCDC charger)? @Horsefly my setup is very similar to your brother-in-law's, although I have a 'dumb' alternator and am using...

Wow - talk about nice bluewater boats! I've only seen them in pictures and read on internet, but beautiful! I love the Beneteau and seems like I have been in electrical upgrade 'planning' mode for quite awhile. I'm wiring for the max loads, but in reality would not expect to get near full...

Thanks Mike, Understand - I should not connect the output from the DCDC charger, directly to the same 'input' on the battery isolator (together with the alternator). Jeff

Thank you - Is it correct that if the AGMs are not being charged (resting voltage ~12.8), and the LIFEPO4 batteries are being charged from separate source at ~14.4v (e.g., from solar or shore power), then I could set the the DC - DC to start charging the AGMs by sensing the LIFEPO4 source...

Thanks FilterGuy! Yes, Victron TR Smart (just added this to original post). Separate but related question and to help me understand how these things should work (note this would not work with my first question - otherwise I would have a 'loop' of charging. This is just separate hypothetical)...

Hi everyone, I've got a 150amp battery isolator with one input, and three outputs. A 125a alternator (w/ standard/non-upgraded regulator) is connected to the isolator input. The first output goes to an AGM battery bank, the second output goes to a separate AGM battery bank, and the third...

Thanks for all the help everyone - It's not how I would set it up from scratch, but here's what I've decided in order to keep changes to existing system/wiring to a minimum: - using existing isolator (which currently splits alternator 3-ways to: house bank, starter, and bow thruster (all AGM...

Joe, did you implement this setup as you describe? I'm adding lithium house bank and would make life much simpler if I just add a dc-dc charger off one of the outputs on my isolator, to get the benefit of alternator charging to my lithium bank.
