BMV-712 Shunt Location and Wiring for Two Separate Batteries on Boat

On my boat I have a single 4D as my house battery and a Group 24 as my starting battery. Both are in plastic battery boxes on either side of my engine so the distance between them is about 6-10 feet. These batteries are wired separately. I was going to connect the shunt to the house battery as battery 1. I understand the wiring for that, simply removing the negative cable currently on the battery and placing that on the load side of the shunt and running a short jumper from the battery side of the shunt to the battery, then the small red wire to the positive of that battery.

For connecting the Starting battery, do I simply run the other small red wire to the positive of the starting battery? If needed, can I make a butt connection and extend that wire to reach the other battery? I see in the diagram the negative cable from that battery looks like it should go to the load side of the shunt, but since these batteries are wired separate do I even need to worry about that?

I also have the temp sensor but I think if I am monitoring two battery banks I cannot use that, correct?

Also, where should the shunt be installed? Inside the top cover of the battery box or elsewhere. It is on a boat so not sure about keeping it protected from the bilge area.

Color Control GX monitor install - how to connect MPPT and BMV?

I am working on a customer's 2021 Grand Design Solitude fifth wheel here that I'm installing a victron Color Control GX monitor in.

I'm installing a 3,000 W victron inverter. Pre prepping for the new Smart Phase Selector that he got on the waiting list to purchase on release.

He already has aVictron MPPT 250/100 charge controller for the solar array, and a BMV712 battery monitor that I installed when he bought the 5th wheel.

I have some questions about connecting all this gear to the color monitor.

1. The info that I received with the Color Control gx says that the 250/100 charge controller connects to the VE Direct port on the back of the monitor, but the charge controller has VE Can connector on it. Can I use this port to connect to the monitor with cat-6 cable? Or does it have to be VE Direct, if so, I need the correct cable part number to connect it.

2. The BMV712 is listed as VE Direct connected to Color Control GX. I need part number for this cable also. The wire that connects to the display for BMV712 has phone line connector on both ends.

color control gx add-ons require quite a lot of disassembly to install and I'd rather not have to remove these wall panels more than once to get these jobs done.

I appreciate your help in this, and I'm sure my customer will also.

Some variations to the Victron Van Install

Hi, I have roughly the same requirements as your van install except I don't require 115V. So in summary, it's a 12V system, I have solar which is 2 x 250W into a single Victron MPPT 100/50, a Victron B2B for charging from the alternator, and an electric hook-up. Ideally, I would like to continue to use the MPPT and the B2B, and solar panels. I currently have an inverter but I would like to change to the Victron Inverter/Charger 2000W as per van install. What I would like to know is, 1) is my MPPT compatible with your schematic? 2) Can I use my 18A B2B to charge from the alternator in place of the Buck Boost (including, is it OK to only charge the Lithium batteries at 18A max),?3) Will there be any connectivity issues (e.g. enough ports in the monitor)? 4) Is the grey block in the diagram on the top right the back side of the colour monitor and is the circular grey block in the bottom left by the battery the BMV 712? 5) Can you provide any help with the wiring of the B2B? 6) Do I need to use the GSM module or can I rely on the touch screen and my phone APP. The reason I ask this is because I will be mostly living in Europe and I am not sure whether I want to have another contract for data for the connectivity to the internet.

Thanks in advance for any advice.

MPPT 75/10 and blue smart charger in parallel?

Hey, i'm currently working on a small mobile solar station with a Victron Li-Ion-Battery for education purposes. When the station is outside it should yield its energy via an solar panel and the Victron MPPT charge controller. When not in use, it will probably stay inside for a longer time. For this case it would be great if the battery coulld be charged via the Victron Blue Smart charger off the grid. Is it possible to connect both devices, the Blue Smart Charger and the MPPT solar charger, in parallel to the Li-Ion battery? (VE.Bus BMS will be installed)

To my understanding, since both devices work in the same output voltage range, this shouldn't be a problem.

Many thanks in advance

Ground to house panel? Multiplus

Setting up a basic, non-solar (at this time) powerwall for home to cover short term power outages.

Entire setup is basic at this point:

  1. Multiplus 24/3000/70. Firmware updated. Mounted to basement wall. *Not grounded yet.*
  2. 24V A123 2.45kWh battery (one now, but will expand)
  3. Heavy gauge plug from AC-IN on Multiplus to simple 20amp wall outlet next to home electrical panel (13A limit set on multiplus). Then, heavy gauge extension cord on AC-OUT to power fridge and misc. essentials during power outage.

Idea is to charge off grid power and use only for essential during outage.

Problem: If battery is plugged in, home circuit breaker trips within seconds. *Multiplus is currently not grounded, so I understand this may be a key factor.

Question 1: Is the tripping likely due to case not being grounded? Or, is it surging too many amps on initial charge (note I have it set to 13A IN limit, but still trips) and I simply need a bigger breaker?

Question 2: Where should I safely ground it? Wouldn't it be natural to simply pop the home electrical panel and run grounding wire to main panel ground bar?

Thank you for your input; this is an awesome community!

Battery cable length in manual, one way or return?

In reading the manuals for inverter /chargers, it isn't clear whether the lengths in the table is one way or total cable length,


Also the Victron toolkit, the cable length automatically calculates return cable lengths as per

This is in

0-5 m cable length: 4 x 50SQmm 5-10 m cable length: 4 x 95SQmm Cable length stands for the distance between the battery connections and the Quattro connections !!! Recommendations are without other loads in the system and these also should be taken into account for proper main battery, main fuse & main switch cables !!!

I read that statement as a one way distance, it would be helpful if the manual was a little clearer in this respect. a 2.5 M run from battery post to inverter is very challenging in a marine installation... so I am just wanting some clarifications on these recommendations

US Certification for Victron Inverters

I'm trying to figure out if Victron inverters are US certified?

My solar installer is saying he can't use Victron because it won't pass inspection in Washington state (US).

I found the below certificates on victron's site, but my installer says he doesn't see a listing for US or at least one that Washington State recognizes so he can't legally install it.

I sent a mail to Victron to ask for clarification, but figured I might post here as well just in case someone here was able to help figure this out.

I've read through the tutorial on VE SystemConfigurator and see that a similar example (3 phase gen with single phase shore power) requires 4 Multis.

Do we need 4 Quattros if the customer wants to keep his single phase gen? Or do we tell him to purchase a 3 phase gen?

Is it possible as a customer to get a installation manual, that I can't find online about easysolar 24/3000/70?


In fact I would like to be able to progrès in my installation, without bothering my dealer especially on a Sunday, and I find that it lacks some info for an individual for the connection and config of an easysolar 24V, 3000VA, 70A.

Normally in manuals, we should find features and installation instructions, and the first diagnoses of Troubleshooting

This is the case for the mppt controller and the inverter charger that makes up this easysolar!

But I can't find the right one, for the whole easysolar.

I was on the victron site, the support section...

Which evokes:

1) Manuals

2) Suppliers

3) here ;)

In manual, I find a sub menu that inclues 'easysolar'

I selected it, And nothing about my easysolar 's manuel , but more interesting and technical notions of the rule of 1 to 1 regarding AC coupling, or info on VE, direct and many other things but not the manual I'm looking for (if possible in French)

I also go to see the 'old documentation' section

Nothing found either.

Basically what is specific to the regulator, the charger/ inverter, CCGX that I have the manuals of these sub-elements.

For a regular installer, It's simple!

I hesitated to disassemble the bottom hood where are the circuit breakers ..., on the face of it, it was good to do and for a concrete example:

the connection of the battery (classic lead) :

Or can you find the manual of this circuit board and its elements where you have to connect at half height of this easysolar the cables of the battery

Admittedly to say the least battery is written on the PCB, But for the most two screws could have been possible with a black element between the two (fuse?) for the positive connection.

In new approach to this philosophy victron (which I still like hihi) I remain a little in hesitation, battery connected, the CCGX screen of the easysolar lights up without having to intervene on any button the central button between the lights remaining on off

We don't know for sure if we should continue with settings? I saw that on my Android app a new 'friend' (smart mppt...) was present, so I allowed him the connection and the update proposal, I launched it, then updated it surprised me but maybe it must be incremental, and that went well ...

Logically I was going to continue to cable the entrance photovoltaic panels ... If this screen hadn't lit up on its own.

Finally, the process for installation, and therefore the first commissioning seems incomplete to me with the documents handed over.

Just before I started with the installation of a BMV712, and for this element I followed the installation procedure from A to Z, no doubt, but in terms of the interconnections between the basic elements of the easysolar,

My next Doubt concern the 'ground' markings, on the PCB.

I just have to connect the mass of the case below at the bottom right on the ground socket of the installation or I must also add the points notes ground on the circuit board ?

Well understood that there is a secure management of this next ground connection whether the AC input is connected or not... And I think that must be the right option for France by default.

Finally I think I lack a general manual on the whole of this easysolar.

The wiring documents provided for the multiplus do not mention the peculiarities of this easysolar and the interconnection already wired for most of them.

Thank you for any help on these multiple uncertainties. And especially on the magic link download of the installation manual of this easysolar.

Kind regards

Multiplus 3000 Split Phase Voltage Issues


I have two Multiplus 3000's in an RV split phase with 50amp shore power (two legs of 120v power in USA). The units are configured in split phase and are hooked up to a 12v lithium battery bank with 800 amp hours of power (8 batteries in parallel).

I am experiencing a weird issue, where one leg's input voltage from shore will drop down to ~100 volts and the other leg will increase to ~135 volts causing my surge protector to trip briefly then everything resets after 1-2 seconds and the cycle repeats. I've tested in multiple locations and this is occurring in multiple locations so i've ruled out the shore power actually being the issue (i think, open to suggestions but this has occurred in 10 locations. We also just replaced our surge guard transfer switch to check if that would fix or be the cause). The issue seems to occur extremely frequently (every 15 seconds) when running a 1500 watt or more load on either leg. We have tried both dynamic current limit and without and UPS function and without with no noticeable change. When the issue is occurring the units will switch from float to inverter and back in a fraction of a second I think because of unhealthy input voltage. We are running through the system checking for loose wires but don't expect to find anything but will double check.

Everything works fine on battery and when not connected to shore power.

I'm curious if anyone has ever seen this before and if it may be a firmware issue or a result of a split phase configuration issue? We are running the 430 firmware that came with the units and didn't want to upgrade without checking here first if anyone has seen this issue.
