3 phase Microgrid with Fronius (AC and DC coupled) Output 2

I was wondering how the Output 2 on a Quattro or Multiplus 3 phase micro-grid with Fronius works. If the Fronius is on Output 1, how do the Victron inverters make Output 2 operate? Does it operate as it normally does in a normal three phase installation without Fronius?

Where is the 100/30 SmartSolar Controller ground connection?

Hi, I am installing an MPPT100/30 Smart Solar charge controller to a small camper trailer. There is no 'earth' as such in the existing wiring as the battery bank of two 100 a/h deep cycles is wired direct to common positive and negative busses. Is it necessary to connect the body of the controller to the negative post of one of the batteries?

Quattro Parallel Operation

Dear Members,

My first post on the forum and I would be very grateful for any guidance/confirmation that can be provided.

We have just upgraded our boat and the biggest challenge and cost is going to be upgrading the electrical system onboard. I do have a 9.5kva generator and shore power when available. Battery bank is 12V and provides power for all “essential” operational equipment. I intend to provide all other consumers at 220V.

I’ve read that the Quattro’s are capable of parallel operation and intend to upgrade and install 2 x 5000W 12/220 units in parallel providing approximately the same power as the generator and more than normal shore power at 15/30A (I also get a little redundancy if/when issues arise).

Questions:

· Can I run shore power and split to both Quattro’s? I believe the answer is yes

· Can I run generator and split to both Quattro’s? I believe the answer is yes

· Can I take the 220V output from both Quattro’s and common them up before running the common power supply to my 220V distribution board? The point I need guidance on

Best regards

Paul

ENtstörung Victron 75/15 MPPT

Guten Abend,

ich Betreibe ein 120W Modul und eine 100Ah Solarbatterie gemeinsam mit einem Victron 75/15 SMART Laderegler. Den Lastausgang habe ich auf einen Philipi Sicherungskasten aufgelegt. Hier gehen dann entsprechen die 12V Steckdosen, Lichter, und Autoradio ab. An der Steckdose habe ich heute eine Verstärker (Teufel Rockster) angeschloßen und über diese Verbindung wurden sehr starke Störungen eingeschleift das dieser erst brummte und dann anschließend abschaltete. Gestern bei bedecktem Himmel gab es keinerlei Störungen bei gleicher Konfiguration. Kann es sein das auf dem Lastausgang nicht entstört ist und das pulsen der Batterie hier übertragen wird?

Gestern war die Last höher als die Einspeisung am Solarmodul. Ich überlege gerade hier einen großen Kondensator aufzuschalten um diesen Lastausgang zu entstören. Kennt jemand diese Phänomen oder hat schon einemal jemand den Lastausgang im Oszi betrachtet?

Andere Vorschläge?


Liebe Grüße

Dual Throw Circuit Breakers

I am looking at a Victron MultiPlus 12/3000 on a yacht. I currently have a little baby Pheonix inverter. It will be shore power connected and invert from the the battery house bank.


I seem to vaguely recall when I researched inverters that one of the switches on the circuit breaker panel for many other brands was dual throw - but that Victron Inverters didnt need to worry about this (was it because Victron inverters and phase match shore power and inverted power?)

Have I remembered this correctly - that I dont need a dual throw breaker?

Isolation transformer earth connection

Just confirming here that when my boat is floating on the water there should be a link from the input PE terminal to J34a.

So, the earth wire from the shore power supply flex is connected to the input PE terminal and I make a small wire up with a female spade connector from this input PE terminal and connect it to J34a?

This transformer is not the auto 115v - 230v switching model

Help choosing charge controller and what will i need to change to maximize solar charging

I am not sure if this is the correct choice, I am currently seeing 30 amps of charge rate but will not keep that up until the lifepo4 battery is charged, it will kick into float very early in my opinion.

AC INPUT 2 VICTRON QUATTRO

Hello everybody,

I have a Victron Quattro 5kVA/120V setup with a MPPT 250/100 and lithium batteries BYD B-BOX PRO 10.0. AC INPUT 1 has mains electricity of the grid.

I want to use the AC INPUT 2 not with a convencional generator but with the output of a eolic system that is installed in the same place, with another battery bank. The inverter output of this system is: 8kW / 127V single-phase (máx output current 63A).

I didn't find any question here about a hybrid system (solar+eolic) like that. The Victron setup will be the same as with a generator in the AC INPUT 2?

Is there anything else to pay attention besides the configuration?

10KVA Quattro Inverter -

Question. 1
My 10KVA inverter periodically changes over into inverting mode even though the mains
power supplying the inverter is not switched off? my supplier (installer) says this is because the
incoming AC supply from the municipality is 'Dirty'. AC waveform seems ok to me.
+- 220v to 240v continuous.

Has anyone had or seen this behavior before?

[image]


Question. 2
My batteries have also been giving me issues lately and the supplier replaced 2 of them last week
since they failed their load testing cycles
These are 8x 12v Victron AGM batteries. 2 x (4 x 12v) in Parallel with each other.

I noticed on one of the charging cycles after we had a municipal power failure the Batteries discharged to around 50v then the power came back on but the inverter tried charging the batteries at 52v this charge voltage should have surely been between 55v to 57v ?

Has anyone had this behavior before ?

Filax 2 Problems and Faults

Hi there,

I have a new Phoenix 12/1200 inverter powering a 140 watt computer setup through a new Filax 2 transfer switch.

The inverter is connected to the priority source side of the Filax 2 and shore/mains power is connected to the alternative source side.


This works fine but I have noticed some odd quirks of this setup.


-Both power sources need to be connected and ON for the Filax to successfully begin feeeding power from the inverter.


-If the whole system is off (mains power disconnected, inverter off), after switching on the inverter, the filax will not allow current to flow from the inverter until the mains is on.


-Leaving the inverter on all the time fixes this issue, but has a 2 amp standby current draw.


-Reversing the setup works fine! Mains to Priority, Inverter to Alternative. Everything works perfectly.


So, i suspect the issue lies with the inverter/filax combintion. Perhaps the filax is too sensitive and detects a voltage/frequency drop of the inverter first startup and cuts out. The inverter runs 16mm2 power cables which are 1m long.

Oddly if i disconnect all loads from the inverter (monitors etc) the filax will successfully start without mains power connected, but after connecting loads carefully, it disconnects. Connecting mains power 'reassures' it that everything is ok and then all is fine and cut-in cut-out works perfectly.


The irony of this fault is after a full power down, you would need to steam back to port to connect to the mains, to reconnect your inverter.

Thoughts?

Torque specs

I've seen this asked before after searching without an official answer from Victron so I'll ask it again. How do we find the proper torque specs for Victron products? I need them for the 500a shunt and the SmartBatteryProtect 100a and I can find values in any of the documentation. Every other product I am using for my install has proper torque specs in the installation documentation, I am really surprised its this hard to find them for my Victron products.

Wire gauge recommended - Orion Smart TR and 100/20 Smart MPPT

Planning out my install for the above two components. The Manual for the Orion calls for 10mm2 wire (<2m) and the MPPT calls for 6mm2 10AWG. When I look at Ancor's site for marine wire, 10AWG appears to be 5.26mm2 with a max amps of 60A. There is no 10mm2 wire so my choices are 6AWG (13.3mm2; 120A) or 8AWG (8.37mm2 and 80A) the 8AWG seems to be more than what the Orion could possibly output; though on the input battery side, the alternator could in theory output 120A.

1. Can the orion even accept 6AWG wire as into the input?

2. Would it be acceptable to use 8AWG on the Output side (with appropriate fusing)?

Am I misunderstanding the recommended cabling?

New Installation for Home

Hello,

I am investigating options for an installation of solar panels and battery storage/back-up. I live in Johannesburg, South Africa and with the current power challenges this seems like a suitable plan.

However, after consultation with a few experts I am alot more confused as it seems like standard configurations are only being presented.

My questions are:

1. Is it possible to have solar panels installed for the purpose of supplying day time usage only to the entire household. We currently have an average daily consumption of 45kw , about 60% used during the day.

2. As part of the system in No. 1 above, can a battery pack be added to the system that would only serve as back up for essentials like a few plugs and lights.


Currently I have a 1500w inverter with 2 x 400A batteries connected to my lights only. This system has been designed to automatically switch on when there isnt power.

Hope to have receive some help.

Thank you

Good morning all. I have a multiplus 24/5000/120 going into a battery protect 220 then into a 300 amp fuse and then into a Tesla 5 KW battery module. Maybe I'm doing the math wrong but as I understand 300 amps x 24 volts should be good for a 7200 watts?

If I over load the AC side of this unit, will that cause the issue?

Next question... Is the 220 battery protect adequate for this setup?

galvanic isolater and Phoenix Multiplus inverter

Hi

I have just moved into a Marina and I need a little advice. We have shoreline power going via 13 amp socket into the Multiplus inverter, which is a Phoenix Compact Multiplus 12/1600/70. This then runs out to a consumer unit for AC.

Do I still need a galvanic isolater or will the inverter do this for me? If I do need one where does it need to be fitted? between the consumer unit and the inverter or between the 13amp socket and the inverter?


Any help much appreciated
