MultiPlus 12/1600/70 - Modus "Nur Wechselrichter" und Landstrom

Hallo,

der MultiPlus 12/1600/70 hat ja folgende Einstellungs Möglichkeiten:

Aus > komplett ausgeschaltet

An > Laden und Wechselrichter an, Landstrom wird durch gereicht

Nur Laden > nur die Ladefunktion an

Nur Wechselrichter > ?

Und hier ist dann meine Frage: Ich dachte, "Nur Wechselrichter" wäre genau wie "An", nur mit dem Unterschied, dass nicht geladen wird. Also ohne Landstrom wird 230 V aus der Batterie erzeugt, mit Landstrom wird dieser durch gereicht. Mein Multi macht das nicht, sondern bedient sich nur aus der Batterie.

So macht die Funktion "Nur Wechselrichter" doch keinen Sinn.

Laden übernimmt die Sonne. Der Multi soll mir nur 230 V geben. Wenn Landstrom vorhanden, dann diesen und ohne Landstrom, dann aus der Batterie. Genau dafür ist doch die Funktion "Nur Wechselrichter" gedacht. Oder hat jemand eine andere/bessere Erklärung?

Danke und Grüße

Markus

MPPT 450/200 Maximum battery voltage only 62V

Hello,

I have upgraded our ess 3 phase system and added a MPPT 450/200.

Now I am very surprised that this only goes up to 62V battery voltage.

Previously, we had the MPPT 250/100 so I could charge without problems up to 64V.

Also the Multiplus can charge as far as I know up to a maximum of 67 V, so I am surprised that the MPPT 450/200 can not.

Maybe it is possible to raise the maximum voltage to 64V via the firmware of the MPPT 450/200?

It is really very surprising that not all MPPT chargers and inverters can output the same voltages.

I have a Lipo 16S battery that I could charge with the MPPT 250/100 only to 4V per cell, that was ok, but now I can only charge to 62V total that is really a pity.

I hope there is a way to change this via firmware to raise the maximum voltage to 64V.


Thanks for the help and many greetings

MPPT 75|10: Should I rather connect my devices to "Load" output or to a Bus-Bar together with Battery to "Battery" output?

Hi there, I am setting up my MPPT 75|10 SmartSolar charge controller for use together with a 12V Battery and two devices that work on 12V and require about 50W in total. I am furthermore using a 110W Solar Panel (max. Voltage: 18.27V, max. current: 6.03A). Let's get to my question.

I was advised to connect my devices and the battery to the charge controller by connecting two bus bars (for + and -) to the battery output of the controller and all devices and the battery onto these bus bars. I am however now realizing that there is a Load output where I could connect my devices to. So I am wondering if I should rather connect my devices directly to "Load"? What is the advantage and disadvantage of each method? Is it safer to connect directly to Load?

An insight to this would be very much apprechiated, thanks in advance!

PS: I also understand German ;)

AC Lasten werden nicht angezeigt, Batterie wird nur geladen.

Hallo,

ich versuche eine kleine Eigenversorgungsanlage bei begrenztem Platz in der Stadt aufzubauen.

Multiplus II 12/3000, Cerbo Gx, MPPT 150/75, Bluetooth Batterie - Spannungs - und Temperatursensor, ET340, testweise Batterie Liontron 12,8 V 200 Ah BMS. 4 x Canadien solar 370 Wp in 2 Strängen parallel.

Einstellungen sind Eigenverbrauch, Überschusseinspeisung bis maximal 600 Watt, Zielwert 50 W.

Mein Problem:

Das Gridmeter (Einstellung AC-Loads) erfasst auf 3 Phasen korrekt den Stromverbrauch. Es wird jedoch kein Strom aus der Batterie entzogen. Es werden auch keine AC - Lasten angezeigt.

Netz hängt am Multiplus an AC in.

Bei kritischen Lasten stehen immer nur 13 W, wahrscheinlich Eigenverbrauch des Systems. Zudem wird, selbst wenn Sonne auf den Panelen steht, sobald die Batterie auf 100 % geladen ist keine PV - Leistung angezeigt, maximal 12 - 20 Watt, obwohl vielmehr kommen müsste.

Wo könnte hier der Fehler sein ?

ESS-managed batteries on 230V split single phases

Hi all, here in the UK I’d like to buy an ESS system to provide PV battery storage on our 2 x 230V/100A split-single phase grid supply. I’m thinking of dual MultiPlus-II 48/10000/140-100 units plus Cerbo GX.

My question is, can each MultiPlus-II be connected to the same battery array? It would be great to be able to significantly reduce the problem of frequently exporting on one phase (with no financial gain) whilst importing on the other (at large financial cost!).

For the batteries I’m looking at Pylontech or BYD but would welcome any opinions and suggestions especially if there’s a specific type of battery which could be connected to both phases at the same time and still be managed by the MultiPlus units. Our PV is 26 kWp with grid usage at about 50 MW/year.

If anyone can help with my battery question or offer any other comments, please let me know!

I also need to find a distributor/tech support.

Many thanks,

Glenn

Same VRM installation with multiple battery sets

Hello,


I have a setup with the following devices:

  1. 1 x 12/2500W Volt inverter
  2. 1 x 12/1600/70 Victro Multiplus inverter charger
  3. 2 x Victron bluesolar MPPT 100/50
  4. 2 x 150AH Lifepo4 batteries
  5. 1 x 200AH Lifepo4 battery
  6. 1 x Victron SmartShunt
  7. 1x Rasberry Py with Venux OS

I am only powering 220V AC devices.

I recently added the Volt inverter to increase AC out power of the whole system by supplementing the Multiplus. I am thinking to have 2 separate systems:

A. AC IN source composed of 1 + 3 + 4 + 6

B. AC OUT - 2 + 5

Could I add both systems in the same VRM dashboard? Would there be any conflict in terms of voltage / current reporting in the dashboard?

I am thinking about the 2 separate battery sets (4 and 5) and wondering how the VRM would see them since the Multiplus use and monitor one battery set and the MPPTs are charging the other battery sets monitored by the shunt.

Thanks,

George

Smart Battery Sense

Habe ein Smart Battery Sense an einer Liontron 12 V 220 Ah; Cerbo Gx, Multiplus II 12 V 3000 W.

Bei den Geräten wird das Battery Sense angezeigt, Firmware ist aktualisiert usw., aber in der Remote Control wird das Gerät immer nur als "unterbrochen" angezeigt. In den langen Anleitungen habe ich gelesen, daß beim Wechselrichter Dip Schalter 1 ein und Schalter 2 ausgestellt werden muss. Nun hat der Multiplus II aber keinen Dip - Schalter.
Was kann ich nun tun ?

PV-Sizing für MPPT 150/45 + 6 x Trina Solar Vertex S 400Wp

Moin,

es gibt bereits viele Threads zum Sizing der MPPTs aber keiner gibt mir "wirklich" eine belastbare Aussage.

Warum werden beim MPPT Calculator keine Warnungen ausgegeben, dass man die Nenn-PV-Leistung aufgrund der System-Voltage-Beschränkung gar nicht richtig ausfahren kann ? Oder verstehe ich da etwas falsch ?


Die TSM-400 DE09.08 haben folgende Daten

Power Tolerance-PMAX (W) 0/+5

Maximum Power Voltage-VMPP (V) 34.2

Maximum Power Current-IMPP (A) 11.70

Open Circuit Voltage-VOC (V) 41.2

Short Circuit Current-ISC (A) 12.28

Module Efficiency η m (%) 20.8


TEMPERATURE RATINGS

NOCT(Nominal Operating Cell Temperature) 43 °C (±2 K)

Temperature Coefficient of PMAX -0.34 %/K

Temperature Coefficient of VOC -0.25 %/K

Temperature Coefficient of ISC 0.04 %/K

[image]


Der MPPT Calculator spuckt mir für eine bspw. 3P2S Config unter STC eine Stringspannung von 102,6 @ STC aus. Wenn´s heiß / kalt ist beim Strom / bei der Spannung genug "Luft" für den Regler.

Allerdings - so verstehe ich es - muss ich nun die Systemspannung von 48 Volt (MP-II + Pylontech Akku Pack) x Strom der 3S2P Config nehmen ??? (48V x 23,4 A = 1.123,2 Watt) , welche der Laderegler "vom Dach holen" kann ? Also gehen 50 % der möglichen 2.4 kWp der 6 Stk. Trina´s ins Nirvana bzw. können nicht "verarbeitet" werden ?

Bitte klärt mich auf - scheine hier ein Brett vorm Kopf zu haben ... vielen Dank !

Miltuplus II - charging from MPPT no to ac loads

Hi

I am newbee in Victron, have Multiplus II-GX. I have one question, system is set to ESS with little feed-in and SOC for battery was set to 20%, i have small problem in the morning where i have some power from MPPT but its used for charging the battery not to use it for AC loads. AC loads are fed from grid (for money). How can I set system to use MPPT and battery to fed the AC back again? It worked at night (using battery not grid) until SOC drops down to 21%.

Multi rs solar - Warning#59 acin1 relay test fail

Hi everyone.

Yesterday I have turned on my solar installation, and one of the problems showed up.

When inverter is working without grid connection everything is working perfect. No problem's at all. But when I turn on grid supply the warning #59 ACIN1 relay test fault.

[image]

Sometimes it's also showing warning #43 ground fault detected.

All this problems are when inverter is connected to the grid. Without grid all working perfect.

I have traced wires checked connections 10 times, polarity is totally fine, all grounding is fine.

Any help would be appreciated.

Efficiency much lower when drawing from both battery and solar compared to solar only?

I have the Multiplus 2 48v with 120v output (Model pmp482305100) that is 95% efficient. My charge controller is a 150/35 that is 98% efficient. My battery and nearby equipment is at about 90 degrees Fahrenheit or 32 degrees Celsius. I've attached 2 pictures showing common situations where the load is run off solar only and where it's combined solar and battery. I have no DC loads other than the Victron equipment itself. The battery is a 5.12kWh SOK 48v battery.

When powering a load with both AC and solar I'm at 76.5% efficiency. 577W/(255W+499W) When powering a load off solar only I'm at 92% efficiency. (155W+274W)/467W

Any ideas what could cause such a drastic difference?

Dive Compressor

Hello

I have a bauer various dive compressor on our boat. Single phase and about 1hp.

We have 660ah of Winston lithium and a Victron Quattro 12v 500w inverter.

We also have a Dolphin M6 generator which is identical to the Paguro 600 rated at 5kw.

The dive compressor works fine on shore power.

It will not run directly from the inverter on battery power it trips and says inverter overload.

I have tried this with the Generator running but still I get Inverter overload ?

The compressor is connected to one circuit in our boat that has a 20A trip fuse which isn’t blowing it’s just the inverter that is saying inverter overload.

When I turn the compressor on it tries to start but after maybe one or two revolutions it doesn’t sound right and dust out.
