Earthing a Victron 500VA inverter

I have just purchased a Victron 500VA inverter and in the instruction manual, it states that the device must be earthed. Could someone who understands the product explain why please?

My application is as follows:

I have a small (2 m X 2m) wooden walled concrete floor remote building in the U.K. with no a.c. mains power. It houses some equipment related to astronomy -

a telescope mount requiring 18V DC supplied by a switch mode PSU

A camera requiring 12v DC supplied by a switch mode PSU

Some microcontroller related control hardware 5V DC - supplied by a switch mode PSU

a 300W , 240V dehumidifier for sucking the moisture out....

Because there's no a.c. mains, I've set up two 12v lead acid batteries in parallel and I charge these via solar panels and an MPPT controller.

The Victron 500VA inverter will be used to provide mains power from the 12V batteries and the SMPS mentioned above are powered by this.

Thanks very much for an explanation of why the Victron must be earthed.

Zeitschaltuhr am Lastausgang

Hallo liebes Team,

Ich habe online einen Laderegler Victron MPPT 75/15 gekauft.

Nun bin ich am erstellen einer Inselanlage mit 2 x 100 Watt SP in Reihe, Victron MPPT 75/15, Batterie-Spannung 24 V, 2 x 12 V Batterien in Reihe.

Am Lastausgang hab ich eine Zeitschaltuhr mit Betriebsspannung 12V/24V. Wenn die Uhr versucht den Schalter zu schließen, zu hören an einem mehrfachen klacken, schaltet sich aber der Lastausgang am Laderegler aus? Manchmal nach ein paar Sekunden oder nach bis zu zwei Minuten und wiederholten versuchen funktioniert es dann. Es sieht aus als würde der Laderegler den Lastausgang einschalten und wenn die Schaltuhr den Stromkreis versucht zu schließen wieder ausschaltet.

Beim Schließen des Stromkreises fahren zwei RaspberryPi hoch und ein Lan-Switch wird eingeschaltet, hängt alles hinter einem Abwärtswandler 12V 24V zu 5V 15A 75W. Strom fließt dann ca. 0.5 – 0.7 A. Ich hab’s jetzt auch ohne Last versucht, ist dasselbe. Zeitschaltuhr direkt an der Batterie funktioniert, also kein Fehler bei der Uhr oder der Verkabelung…

Hab Angst, dass das System sich irgendwann gar nicht einschaltet, oder dass etwas kaputt geht…??

Hab die Last im Moment direkt an der Batterie, aber da verliere ich ja verschiedene Funktionen...

Vielen Dank!

Way to get two 110v outputs from single inverter/converter from battery power?

PROBLEM:

I am trying to run a Level 2 car charger off my battery bank; I am currently running a Level 1 off my battery bank using the MultiPlus Compact 24v|2000VA|50A which works fine.


RESEARCH:

I was looking at the Victron Energy Quattro line of Inverter/Converters; I noticed that Victron makes an Inverter/Converter that can output 208+ as long as both the L1 & L2 are plugged in.

When the battery is the only supply voltage it then chops the voltage down to 110-120v. After reviewing this diagram (https://www.victronenergy.com/upload/documents/AT-3-split-phase-120V-to-120-240V-with-Quattro-120V.pdf) and talking to Nothern Arizona Wind & Sun it sounds like I would have to buy an autotransformer in addition to the Quattro.


QUESTION(S):

- Does this sound like the right approach?

- Does Victron have a device that outputs two phases of 110-115v to form 220v or not?



Thank you for any help!

Help defining specs charger/inverter and battery protect CAMPERVAN

Hi all! :-)


I am a young an enthousiast girl buzy with a camperitzation of a van (not sure how far I will get but I'll try!) and I saw and read a lot of information, but I have some doubts about which criteria to follow when choosing Victron equipment. Hopefully someone can help me! My apologies upfront if I'm asking stupid questions :(


My system will have:

- 2x320W solar panels

- 2x170 Ah 12 V batteries (link 1 or link 2, to be decided) --> are these ok for the application?

- 1x Relay RL-180/200 12 V to connect to the alternator

- 1x SmartSolar charge controller 100/30 (because max current both panels is 21 A)


But I am not able to define what are the specs that I need for the:

- Multiplus inverter/charger from Victron:

First question is, do I want a module that does alltogether or shall I buy separate components? Second question: which is the power that I need for the charger and inverter side?

My consumers in 230 V are:

[image]

Total A/day = 23,73; Total W/day = 5458

My consumers in 12 V are:

[image]

Total A/day = 102,88; Total W/day = 1234,6

Third question is: I want to install an outer power take off to connect to the camping 230 V socket and charge/use the 230V consumers with the electricity of the camping mains. If I would connect the vehicle to the camping socket, will the multiplus inverter/charger charge the batteries and allow me to use my 230 V consumers at the same time? I want to avoid the situation of connecting to the camping grid, batteries not full and using 230 V consumers and not having enough power, since with a 10 A socket from the camping, I can only consume 2300 W (3680 W max with 16 A). Like: I plug to the camping socket and I plug my hairdryer, does the inverter charge at the same time the auxiliary batteries? If so, with a 12/1600/70 model and a 1000 W hair dryer, I could not connect many more things since the inverter can deliver max 1300 W!

Is the 12/1600/70 indicating the max charging current of the battery? What is the maximum charging current of the batteries? 170 A?


Also not able to define which:

- battery smart protect: fourth question: which of these 65A/100A/220A ? or another?


Sorry for my lengthy email, but I am new in this field. Every help is very appreaciated!


Many thanks in advance,

Wendy

Orion TR12/12-18 NOT isolating the start battery

Hi,

I have the Orion TR 12/12-18 DC-DC isolated charger fitted between my (euro 6) start battery and my leisure battery but have flattened the start battery twice now when parked up with the fridge running off my leisure battery so have a couple of questions:-

1, Isn't this charger supposed isolate the start battery from the load (leisure battery) when the vehicle is not running, the way a split charge relay does?

2, Even though it's an isolated version, can it share the vehicle body negative or do I need to run a cable between the battery - terminals and charger?

3, Is there a link for a list of faults and fixes somewhere to save people asking similar questions?

4, When setting it up, what is the ideal voltage output the pot should be set, I think it's pre-set to 12.3v which seems low?

Thanks in advance.

MultiPlus Compact - second battery connection - charge function?

Hi,

I have a Multiple Compact 800 24v with the secondary output connected to start battery to trickle charge when parked up.


Question - does the 800 only power the second battery output when AC is connected or does it also take power from the primary connection (leisure batteries) to cross charge the secondary battery when the AC is off?


Reason for asking is that it seems to work the second way as I see current flowing to the secondary connection even with AC off!

Help with Victron Multi Plus Firmware Settings using 3.2 V prismatic batteries

Hello,


I’m a solar rookie and I’m almost ready to fire up my first system on my RV conversion project (fingers crossed).


I’m running 1260 watts of solar (six 210 watt panels), a 24 volt battery bank consisting of 16 LiFePo4 CATL 3.2 V 271 ah cells, Victron 150/60 MPPT, Victron 24/3000/70-50 Multi Plus, Orion 24/12 DC/DC converter, Electrodacus SBMS0 mainly to keep the cells balanced.


I have not hooked up the batteries yet or performed the initial Multi Plus firmware update and related firmware setting changes.


I came across a video that showed the Multi Plus firmware settings.

I reviewed the Victron Multi Plus Service Manual document and it does not provide the specific information related to each option that I expected would be necessary and important in order to make sure each setting is setup correctly for safe and successful functioning. Many of the settings I couldn't even come up with a reasonable guess as what to enter.


If anyone has ever setup a similar Victron Multi Plus and LiFePo4 prismatic battery system would you be kind enough to provide the Multi Plus settings which are working successfully for your system?


I know there are a lot of setup sections and I apologize for this HUGE ask, but since Victron components and these CATL, EVE, Lichen prismatic type batteries are so popular, I”m sure many others will also benefit from this information too.

De positie van Victron

Goedemiddag forumleden,

(Wanneer ik dit hier niet mag posten, zou dit bericht dat weer kunnen worden verwijderd?)

Ik ben Patrick van der Wal, 23 jaar oud en momenteel studeer in Ondernemerschap & Retailmanagement aan de Hanze Hogeschool in Groningen. Voor een tweedejaars project hebben wij de opdracht gekregen om de externe omgeving van een bedrijf naar keuze in kaart te brengen. De blauwe kastjes in onze zeilboot vielen mij altijd al op en van het een kwam het ander. Een onderdeel van dit onderzoek is dat ik het customer relevancy model moet invullen waarmee ik voor mijn opdracht het bedrijf zou kunnen positioneren binnen de markt.

Nu is mijn concrete vraag aan de 'fans' van Victron, wat vinden jullie belangrijk punten bij de volgende elementen: toegankelijkheid (bijvoorbeeld altijd en overal kopen/fysieke winkels), beleving (aanbieden van interessante content/ contact met de community (zoals dit forum)), prijs (laagste prijs garantie/gepersonaliseerd/ locatie afhakelijk?), product (breedte en diepte van assortiment, uitgebreide infromatie, vergelijk optie?) en service (spaarprogramma, persoonlijke service, live chatten met experts garantie?). En op welke punten vinden jullie dat Victron echt uitblinkt? Om het te vertalen naar een praktijkvoorbeeld: Jumbo supermarkt blinkt bijvoorbeeld uit in de laagste prijs voor A-merken gekoppeld aan een zeer uitgebreid assortiment.

Nogmaals: wanneer dit niet mag, schroom dan niet op dit bericht weer te verwijderen! Anders ben ik zeer benieuwd naar jullie meningen en helpen jullie mij verder met het behalen van mijn EC's. En misschien heeft Victron ook nog iets aan mijn uitkomsten haha!

Model selection needed - Also Input Voltage 120V versus 230V. Help please.

In my RV, I currently have 12V battery and 120V "shorepower". My generator is Onan 10KV "Quiet Diesel", configured to output 120V.
The inverter for this system is junk. It does not "power share" and it's constantly breaking down.
I am also considering a new airconditioning system that requires 240V (US Standard).

So, there are a couple of background situations.
1) I can easily reconfigure my generator to 240V output (240V on two 120V output "legs"). My shore power cord and transfer switch are already configured to handle 240V but the actual feed into my current inverter-charger is single-leg 120V.
2) I will need to install new 240V wiring to the new airconditioning system from a new 240/230V interter charger. No problem.
3) I have approx. 700 Amp/hr of battery capacity (AGM, 12V). This battery bank would be easily reconfigured to 24V by recabling pairs in series. Again, no problem.

My technical issue : Frequently, I find that I'm limited to 120V input on the road. This can be 15Amp/120v (ordinary household current outlet) or 30Amp/120V ("TT" RV connector). I have 240V service at my home shop/garage and many RV parks have 240V outlets, but not all.
So, a basic question, Does Victron make an RV-suitable unit with about 4KW, 240V output that will accept either 120V or 240V shorepower/generator input? If so, which Victron model will do this?

Assuming the answer is no, what's the best arrangement?
Using a 120V - 240V transformer with a 240V inverter charger (with 240V input from the generator) and running a normal 240V house system from there? With load-balanced split legs for house 120V circuits and 240V to the airconditioning system.
Or use a 120V inverter charger, continue to use 120V from the shore power and generator, with a 120V - 240V transformer fed from the inverter-charger output to power the airconditioner system?
(All the above considers the battery bank configured for 24V). Which Victron model inverter would be best?

Thank you. I look forward to converting to Victron for my RV power needs.
