My wife and I took the plunge and bought a 1984 Roughwater Trawler for live-aboard (Semi-retirement). It needs a major upgrade when it comes to the electrical side of things that's for sure. So far I have made a list of the upgrades I'd like to make.

MultiPlus II 12/3000

Orion-Tr Smart 12/12-30A (360W) Isolated DC-DC charger

Victron SmartSolar MPPT 150|70

Lynx Distributor

Victron BMV-712 Battery Monitor

Smart Battery Protect 100A

Galvanic Isolator VDI-32

Cerbo GX

GX Touch 50

6x 200W Solar Panels

3x 200Ah AGM Batteries

Now the List that i'm going by currently is from 3000w INVERTER | 400-600Ah | 400 TO 1200W SOLAR-CAMPER by Explorist.life website. I have noticed some wiring diagrams with a battery Isolator and some without when it comes to the Home battery and starter battery. With me using the Isolated Orion do I need to get the battery isolator as well or no?

Hello,

I am designing an upgraded electrical system for my 32' sailboat to LiFePo4 batteries with built-in BMS. If anyone would be willing to review/provide feedback, I would really appreciate it. This design does not incorporate a multi-plus that is in many of the example designs. This is due to limited space, but if it's required please let me know, and maybe I can cram it in somewhere! Thanks!

My main question is how to best control the Orion so that I don't drain the starter battery. I have a Cerbo GX (not shown), maybe this can monitor the starter voltage to shut it off below a certain voltage? Or I could wire a manual switch to turn it on when the engine is running I guess too.

I am on a Lagoon 2013 catamaran and was wondering if anybody has configured NMEA2000 integration between a Cerbo GX and an older Raymarine system running Lighthouse II (ie., no Glassbridge software)? If so was it worth the cost and effort? #LighthouseII

I'm not sure how to ask my question.

I have this equipment, installed by the boat builder:

1. Victron Energy Blue Power MultiPlus 12 VOLT 3000 VA 120 AMP charger inverter.
2. MPPT Solar Charge Controller.
3. Whisper Power Belt Driven Generator W-BD 3.5.
4. The boat has a 47 HP Beta marine engine and two solar panels on the roof.

Item 3, the Belt Driven Generator, periodically displays a fault message that is not in the manual:

0V 0.0A 0.0KW OVER DC BUS

It happens when I run a 1600 watt clothes-washing machine. The boat builder told me the system would handle this.

I have asked two marine engineers, who are not sure what's wrong. I don't know the terminology nor the relative importance of things, so I don't know what questions to ask. So my question is very general: "Is this something that needs to be fixed? What do I need to know?"

Thanks in advance, and sorry if my question is incomplete. I'm doing the best I can. :)

Here is what I have:

2 Yamaha 200's (50 amp Alternator Output each)

2 Optima Bluetop D31M Starter Batteries (75 AH, 900 CCA)

BEP Smart Battery Hub

Here is what I want to accomplish:

House battery setup - Either 1 Relion 12v 100 Amp lithium battery or 2 Relion 12v 60 Amp batteries in parallel

Charge the house bank via an Orion DC-DC Converter, but i have no clue which one.

Possibly a 400w REDARC inverter for phone charing and light loads like that.

How do I accomplish this? I have no clue where to even start?

I’ve found versions of this question unanswered in these forums. It is not answered in the manual so no need to post a link. Since I’m using this on a boat it’s is important to know for avoiding stray-current issues. Are the AC and DC sides of the the transformer isolated?

I am using a Victron 500w (12v) inverter on my boat to power Starlink. It all works fine until I power up the Diesel engines on my boat, and then the Starlink dish goes offline—but the wifi router does not. I suspect there is some interference but have not been able to troubleshoot it.

I built a pontoon boat with a 48V outboard and the SLAs were not getting the job done so we are changing to lithium. I am adding a cobbled together solar charging system and was planning to mount the BlueSolar PWM 48V 30A inside the console. Will this work? If not, will a small daylight source (a hole) work?
