Will the Fuse LEDs on Lynx Distributor illuminate without the 4-pin cable supplied with unit?

Trying to use the Lynx Distributor (and Power In) without the Lynx Ion Shunt or BMS (using BYD batteries). I had assumed the Fuse LEDs would illuminate with a working fuse in place and powered, however a line on the old Victron Live page for DC Distribution Systems suggests that this small data cable is used to power the LEDs (rather than taking power from the busbar itself). I cannot get the LEDs to illuminate - are the LEDs useless unless using the Lynx Shunt? Because Lynx Shunt uses CANbus, it cannot be used in conjunction with BYD on a CCGX (though I think VGX would support it).

Phoenix 12/500 Fuses

Hi

My brother has a Phoenix 12/500 inverter. It has 3x35Amp internal non replacable fuses.

1. What Amp fuse must he use on the battery cable with a 105Amp battery?

2. If one of the fuses on the 12/500 blows; is the inverter then dead? (why 3 fuses)

Thanks!

Welche Sicherungen werden für den Lynx Distributor benötigt

Hallo,

aktuell ist ein Multiplus II 48V/5000 mit 4 x Pylontech US2000C im Einsatz (der Multiplus liegt parallel zu einem alten SMA SunnyBoy PV-Inverter mit max 3kw).

Nun soll das System um einen MPPT Laderegler erweitert werden (weitere 4 Solar-Panels mit je 400W werden installiert).

Als Laderegler wird ein Victron MPPT 150/45 installiert.

Um nun die Systeme zu verbinden, soll zusätzlich ein Victron Lynx Distributor installiert werden.


Meine Frage wäre nun:

Welche Sicherungen sollten in dieser Konstellation im Lynx verbaut werden. Am Lynx werden angeschlossen:

- Victron Multiplus II 48V 5000

- Pylontech Batterie-Rack (4xUS2000C) mit in Summe 4 x 9,6 Kwh

- Victron MPPT 145/50


Aktuell angedacht bzw. mit empfohlen wäre (jeweils als Mega-Fuse 70V):

- 60A für den MPPT

- 100A für die Pylontech

- 200A für den Multiplus II


Ist das so passend? Die vom Multiplus scheint mir etwas zu groß zu sein, oder?

Guest Cabin gets all the solar

Hello! I am building a small guest house (195 square feet / 18 sq meters) behind my home, and want to add a system like this:

*Tied to grid via 30 amp shore power plug-in similar to an RV, but don't want to feed the grid

*Guests can stay and enjoy life 'off grid' using solar and battery, and if battery gets low or there is a need to use appliance that requires more than batteries can provide, just plug in shore power

*If my home loses electrical power temporarily this is a type of backup shelter

I'd like to use Victron components. Based on my initial research is this ok?

1/ two solar panels on roof

2/ Victron MPPT 100/30 charge controller

3/ Victron Multi Plus Compact 12/2000

4/ Victron’s Venus GX

5/ Victron's BMV-700

What kind of AC/DC panel (fuse box) is appropriate? Any suggestions regarding the specific type of batteries to use for this?

Thank you for any advice!

Do I need to add a fuse between 2 Controllers that are connected to a battery that already has a fuse on the positive wire?

This is my planned install for the 2nd controller and a 2nd panel to my camper. The two controllers will be connected to a bus with no fuse.. Is a fuse between the controllers and the bus needed If I already have a fuse between the bus and the battery?

Phoenix 12/500. AC ausgang absichern weil mehrer steckdosen oder verteiler

Hallo welchen schalter/schutzschalter würde ich brauchen wann ich den AC ausgamg vom Inverter absichern will.

Zurzeit hängt manchmal ein 3er verteiler fix da ca 2.5 weg ein kabel zum 230v kühlschrank auf einzelne steckdose dor würde ich gerne 2er od. 3er hin hängen driekt am 3er verteilrr hängt meisten laptop, diverse lade geräte, stabmixer oder auch mal ein 2tes langes weg (wie bei kühlschrNk) nach aussen um mal werkzeug zu nutzen, ein licht anhängen ider evtl auch mal teil meines dj Equipment was auch innen vorkommen kann! Er war auch nie überlast der inverter alles im grünen berreich nur ist halt teilweise echt bisserl "kablesalat" mit langem kabel vom inverter 3er verteiker weg da dran wieder einen Verteiler weil ebem gerade so gebraucjt wird spontan! Das fahrzeug hat KEINE NETZVORANGSCHALTUNG und KEINEN LANDANSCHLUSS mit irgenwelchen umschalt Schnickschnack.....maximal im winter wird von einem benzin 4- takt inverter-stromerzeuger extra ein kabel nähe batterie gelegt (länge immer unterschiedlich)mal steht das aggregat direkt unterm bus u. Dan wieder weit um es nicht zu höhren) und an dieses kabel wird ein victron blue smartcharger 12v15a angehängt der meine batterie ganz klassisch nachlädt oder nichteinmal das sondern der stromerzeuger wird nur extern dazu geschaltet wo dan evtl Laptop oder anderes equip hängt was in regenzeiten zu viek energie frisst!

Wie gesagt ich würde voll gern bei Phoenix 12/500 AC ausgang einen schutz!!! Falls ich mal bei arbeiten das verlängerungskabel durch schneide oder doch mal paar tropfen wasser einfach wo falsch Hinteropfen eo nicht sein soltte naja gebe viele möglicjkeoten warum absichern!


Sooo langer text für eigentlich sehrbeinfach simplen aufbau

Bitte evtl kann mir jemand weiterhelfen und hätte einen tipp welcher FI/LI da sinn machen würde oder zumindest eien LI-schutz wann FI sowieso nicht das bewirkt was der bewirken soll! abb- schutz/schütz oder ähnliches

Für anregung bin ich offen doch die spontane verwendundndurch Verlängerungskabel irgenwo herum am bus und spontan mal einen 3er verteiler dazu weil nötig innemnoder aussen wirds nicht ändern ansonsten offen für alles besten dank

Sonig hitzige Grüße

Help with fuse size MPPT

Hi,


I have a Victron 100/20 MPPT (IP43) and would like to know what size of fuse I need between the battery and the MPPT.


I have a choice between two types of battery cable with in-built fuse where I live in Denmark. I can either get:


- 20a fuse on a 4mm2 (12amg) cable

- 30a fuse on a 6mm2 (10amg) cable


I will be running 2 x 110w solar panels, battery is 100ah.


Many thanks

Turning Quattro off trips output breaker

Hi!


I am having some issues with a Quattro 48/10000/140-2x100 that i installed about a week ago. It is an older used unit with firmware 143.

It seems to be tripping the output breaker in the fuse cabinet when i turn the unit off for some strange reason.

The general overview of the system is:

- Offgrid system, large cabin high on the mountain

- 30 kVA diesel genset 230 V delta connected, cabin is wired with IT ground (no ground)

- Output of generator goes to water heater (L1-L2), industrial dishwasher (L1-L3) and the input of the Quattro (L2-L3). Each of these is fused with 16 A, 25 A and 32 A fuses respectively.

- The other loads in the system is on a separate busbar with a MTS (manual transfer switch). This MTS is basically two interlocked MCBs each with a 63 A fuse. The input of the MTS goes to the output of the quattro and to the generator. This lets me supply the loads directly of the generator if the Quattro is malfunctioning.

- The loads are fused with either 10 A or 16 A fuses. The loads are things like water heater, freezers, fridges, various electronic equipment and lights.

- The battery solution is a 280 Ah, 16S LiFePo4 pack with a 200 A (350 A for short periods) BMS.

- System is configured to turn on generator when the load exceeds 5 kW for 10 seconds.

- I also have an override that always keep the generator on if necessary (for example when using the dishwasher)

- The system is turned completely off each night


Yesterday when the Quattro was set in the off position, the 63 A MTS breaker on the output of the Quattro tripped. At this time the generator was still running (this was turned off 5 seconds later) and when the Quattro was turned off the battery was in a float state, charged to 100 %.


Does anyone have any idea what could have caused this ? I have had it happen once before, but that was when the Quattro turned itself off due to low DC/high ripple likely caused by a BMS disconnect. The cell protection on the BMS is perhaps set a bit too low (3.55 or 3.6 V I believe) , so 100 % charge (56.2 V) is a bit close to cell overvoltage.


I am no longer on site unfortunately and therefore do not have access to the system, but I do have a GX device setup and VRM. Unfortunately it is powered from the quattro output so i do not have much in the way of logs.

RCD placement in Multi-II ESS

Hi - on a 3x MPII 5000 ESS system, Victron requests a RCD Type A on AC-Out-1. We have realized that with a 4phase RCD 300mA. Does this RCD need to sit immediately at the AC out or can there be a distribution block in-between?

Background: we have a thick cable running back from the installation in the garage to the house, so the AC Out RCD is in line with the then following house connection. However, between AC Out and RCD in the garage, we have a block connecting AC out with solar inverter AC, wallbox (with separate 30mA RCD), some plugs (with separate 30mA RCD).

Any trouble/disadvantage with such an arrangement?

Are Fuses or Breakers Necessary Between Battery and Lynx Distributor?

In my set-up the 4/0AWG wires that connect the batteries to the [Battery Bank] Lynx Distributor do not feature fuses. There are fuses internal to the Lynx Distributor, but the wires are effectively unprotected until they reach the Lynx Distributor.

Of course, I’ll keep those runs as short as possible (less than two feet long per wire/conductor) but it still seems weird to me to have a wire run unprotected.


Should I have an MRBF, or similar, fuse directly on the battery terminals?

Should I be using a different fuse or circuit breaker to protect the wires between the batteries and the Lynx Distributor, or is the system safe as it's currently designed?


The wiring schematic in the Lynx Smart BMS doesn't show any fuses in that location.

The example schematic on the Victron Support site doesn't show any fuses here (https://www.victronenergy.com/upload/documents/MultiPlus-II-3KW-230VAC-12VDC-600Ah-Li-Lynx-Smart-BMS-&-distributors-Cerbo-GX-touch-generator-MPPT-Orion-Tr-Smarts.pdf).

On the other hand, this post (https://community.victronenergy.com/questions/108271/mega-fuse-arcing-dangers-lynx-distributor-li-batte.html) on the community makes me think I will need protection, if what that discussion says about Lithium batteries arcing past MEGA fuses is correct.

Easyplus Fuses (Lightning Strike)

Good morning

We have a yacht that was hit by.a lightning strike. Parts of the electronic equipment seem to be damaged. For some others, it‘s fuses that blew and where the device works fine again after fuses were replaced.

The EasyPlus (as well as a Venus GX and a BMV) is dead as well. We have checked connections which all work. We have disconnected the EasyPlus from the VE.Bus (and the Venus), so that no external control interferes with the operation of the EasyPlus. But it‘s dead. No reaction to the switch, no LEDs lighting up, relays clicking. No output of 12V to the battery or 220V from the inverter.

I have opened the EasyPlus, where everything looks alright, no damage, no smell, etc. It seems that the control logic is not working. Before I consider replacing the EasyPlus, I‘d like to ask here whether there is anything I could check. For example, are there any fuses inside the EasyPlus that I should check and potentially replace? If that’s not successful, would it make sense to get the EasyPlus repaired by Victron or should I aim for buying a new one?

Many thanks!!
