Dear Community,

- i have a 3-Phase Quattro 15K with ESS-Setup. (Firmware 497)
- Living in germany required me to setup a external NS-Protection by using Ziehl UFR1001E to comply with VDE-AR-N 4105:2011-08 or VDE-AR-N 4105: 2018-11

- As it is required by my local Network, i need to comply to some settings like for COSϕ, as it is described in DIN VDE V 0124-100 (VDE V 0124-100):2020-06.

- I know the QUATTRO 15K is certified to comply with ...
--> VDE-AR-N 4105: 2018-11...
...based on Test defined in ...
--> DIN VDE V 0124-100 (VDE V 0124-100): 2020-06. “Network integration of power generation systems – Low voltage"...
... by ...
--> Certificate-ESS-VDE-AR-N-4105-2018-11-Quattro-48-8000-110,-48-10000-140,-48-15000-200.pdf

Here comes the Problem:
- VE Configure 3 just offers me Grid-Code VDE-AR-N 4105:2011-08 and within this Grid-Code i also can´t make any changes, e.g. to COSϕ

How can i either change settings on values like COSϕ (as it is for example possible in other Grid Code... (Here TOR Erzeuger Austria..)

[image]

...or how can i get to select Grid-Code...

--> VDE-AR-N 4105: 2018-11 (with external NS-Protection) ... like i have seen it in Screenshots in in a different Post....
Screenshot with QUATTRO having VDE-AR-N 4105: 2018-11

.. where i assume i will automatically comply to the right settings defined by my local network provicer (like COSϕ .. settings)

Hello,

I am trying to find info about Quattro 48/15000 transfer switching time (specifically when the UPS feature is OFF):
- What is the switching time when switching from Generator to inverter and when switching from inverter to generator?
- Is the switching different in a 3-phase connection? and in a parallel connection (2 Quattros/phase)?

- is the switch time affected by load, temperature, or any other determinant?

I have a Multiplus 3000/120 with 30 AMP shorepower connection. The UPS setting is disabled.

My Multiplus was automatically switching to shorepower when connected but I discovered this morning that its not switching over to shorepower to charge my Victron 200aHr batteries. I have not changed any settings in several months.

I checked my wiring and I'm receiving 120 volts to the terminals inside the Multiplus & batteries chare via alternator and solar panels.

Where do I look next?

Hi all.

I'm currently designing a system for my sail boat that I would like to run a Bauer Junior II dive compressor (2.2kW) from a Multiplus 24/5000. My research so far has indicated that people typically spec a 8-9kW generator to handle the start up current of the compressor. In my case, I won't have any generator.

My research has dug up anecdotal evidence of a 5kW inverter (unknown brand) starting a Junior II with a smart softstart from Hyper Engineering. I'm hoping that Victron inverters, given their capability to do 200% for 30 cycles should be able to start the compressor without issue, however I'd like to be a little more certain before dropping the $$$.

Does anyone know of this being done successfully?

Could the MP 5k still start it, even if the ambient temperatures are a bit higher (40ºC)?

Any help is greatly appreciated.

Regards,

Justin

@Botnic How is yours going?

Ve.Bus (275) intermittent low battery alarm and high DC Ripple using Blue Nova Lithium batteries although the battery voltage is ok both on the Battery Voltage and Current (512) and VE.Bus DC Voltage and Current (276). I get the alarm intermittently when grid is lost momentarily. No Battery Warning and Alarm (512) is raised. This issue causes the inverter to switch to off and then restart.

i read on the victron site that the only power input for 3 phase was Y, no delta input allowed.

output can be delta or Y

is this true, some countries use delta and some use 3. this not end user selectable in a particular country

I've been having a massive issue when inverting where my 12V voltage gets under 10V triggering the low shutdown and restarts. I have 2x400AH EG4 batteries which should handle 200A each but its barely usable.

Biggest issue is when its trying to assist shore as I have 30amps and it just shuts everything down again and again

Multiplus inverter/charger 24/3000/70. I need to equalize Rolls 5000 24 V batteries. Multiplus says the batteries are floating. I start the generator manually, set the run time for 6 hours. From our CCGX I start the equalization process. The Multiplus shows that it is in the equalization process because the bulk and absorption LEDS are flashing alternately. The image shows the process starting at about 10.20. At about 12.45 the battery volts reaches absorption volts but instead of battery volts continuing to rise to about 30-31, eq volts, the charger switches to about 26.20, float volts. Specific gravity is still about 1.190.

Not sure what's going on. How can I get the eq to perform correctly?

Hi all.

I would like to know if Victron Quattro inverters and/or MPPT's could possible interfere with an Implantable cardioverter-defibrillator.

"An implantable cardioverter-defibrillator or automated implantable cardioverter defibrillator is a device implantable inside the body, able to perform defibrillation, and depending on the type, cardioversion and pacing of the heart. Wikipedia"

I need to increase my battery capacity and i am thinking to replace my 24V acid lead battery bank by a 48V lithium batteries.

i can reuse my smartsolar 150/35 charges but i would also like to reuse my multiplus conpact 24/1200 inverter.

is there any way to reuse the inverter/charger? Perhaps with a 48/24 dc-dc converter?

thanks

I am new to this and my system was only commissioned at my holiday house a few weeks ago. My setup currently runs on solar all day (unless the weather is bad) and battery all night (unless the battery drops below 40%) other than 300 watts per hour of grid power. If the gird fails, my circuits which are designated as critical loads will run from the battery and 40% of the battery will give them around 8 hours. It appears to me (based on a few weeks of monitoring) that the system will be on “grid only“ power for about 10% of the time (presumably more in winter) and probably increasing to about 60% of the time when we are actually using the holiday home.

My understanding (and I may be wrong!) is that the system will protect from poor quality power (surges, high voltage etc.) from the grid when the battery is in use and when the solar is in use but not when the power consumed is “grid only”. Assuming this is correct, is there any way to protect the critical loads from dirty power all the time using the system or does one need a separate stand alone UPS?

Thanks in advance from a real newbie!

Hi,

When enabling "Monitor for shore disconnect" in Cerbo GX I only get alarms when my MultiPlus is in "inverter" mode if shore power is lost.

If I set it to "charge only" I get no alarms when when shore power is lost.

What could be the cause of this? It would be really nice to have the alarm in "charge only" mode also.

Is there another way of monitor for shore disconnect when the MultiPlus is in "charge only" mode?

I understand that Victron use / recommend a Type A RCD, as it protects against AC and pulsing DC residual currents. While perhaps intuitive to use an RCD that detects DC, my understanding is that for the RCD to trip on the basis of DC, then there must be both a fault in the inverter (to produce pulsatile DC) and a ground fault in an appliance (to incur a residual current fault). If this is the case, there would have to be a double point failure for the DC element of the RCD to operate.

Am I missing something?

I have bought a used Quattro. It seemingly works, but some times it starts to make bad sounds. I tried connecting it with only 50mm dc cables straight to multiple different batteries with no ac connected. Sounds is the same. How ever if it is off for a little it tends to go away again. I made two recordings of the sound: https://www.youtube.com/watch?v=NmyPadE7vqY and https://www.youtube.com/watch?v=CDWX25yAMjA This is not a wiering / battery / ac issue. Any idea what this could be?

Hi

I have a three phase system with Quattro 48|5000's. At the moment its fed by a Fronius Symo 6 on AC-1-out, deliverying 6kVA on full power. I am planning to add about 10kVA solar power on DC side with a MPPT RS450/200. And potentially also a Hoymiles HMS-2000 on, probably, L1 (again AC-1-out).

My queustion is about the limits of the system.
Assume there is full power sun and we get 8kVA from AC-coupled solar (which should be fine with 1:1 rule, 8 < 15). What happens if the DC side power its full 10kVA towards the Quattros? That would mean 10kVA from DC and 8kVA from AC, which is well above the systems 15kVA? Would the GX tell the DC MPPT to go down, preveting the system from overload? Or how are such scenarios working?

Thanks in advance :)
