This is my first post on this forum and I'm new to the world of inverters. The application is for my highend home audio system that I want to feed off the grid with an inverter and an LFP battery pack. One of the very best audio equipment co., Living Voice (UK), uses this same approach with Victron Phoenix inverters. https://www.livingvoice.co.uk/lv-battery-power-supply.html .
My question is relative to the THD the inverter output bears relative to the power reserve it has with the connected load. The load of an audio system is made of a baseline plus constant peaks varying in time (fraction of a seconds) and amplitude (up to 4+ times the baseline load), to follow the dynamic of the music. For example with a baseline load of 400 watts will the THD figure be lower with a 2000 watts inverter or a 3000 watts or even more inverter?
Victron inverters use a 20 KHz PWM full FET bridge followed by a step-up power transformer to produce the output waveform of 115/230 volts. Is this configuration considered as a low frequency inverter or a high frequency inverter. Is this specific configuration the reason Victron uses the expression Hybrid HF technology?
Victron doesn't say much on THD other than saying that it is <3%. Does this figure apply at max. load or low level load?
I am looking for a reference for the available DC fault current and duration for the Skylla IP65. It isn't stated in the datasheet or installation manual. Possibly it is stated in another document? Note: fault current from the battteries is easily calculated and is a different aspect
Does anyone know of a Victron resource that describes and explains the various terminology in the Victron Inverter NS Protection Logs?
I am looking for clear definitions on:
2. Phase Angle Deviation
To whom it might concern,
The BMS 12/200 manual incorrectly says on the schematics drawing that "Up to five 12,8V LFP batteries can be connected in parallel" whereas the spec table in the same document and the datasheet says 10.
In VEBus firmware numbers.txt, is there any reason the 500VA is called a "Multi" but the 800VA and up are called "MultiPlus"?
2660 Multi 12/500/20-16 2661 MultiPlus 12/800/35-16 2662 MultiPlus 12/1200/50-16 2663 MultiPlus 12/1600/70-16 2665 Multi 24/500/10-16 2666 MultiPlus 24/800/16-16 2667 MultiPlus 24/1200/25-16 2668 MultiPlus 24/1600/40-16 2670 Multi 48/500/6-16 2671 MultiPlus 48/800/8-16 2672 MultiPlus 48/1200/13-16 2673 MultiPlus 48/1600/20-16
Hi, can’t seem to find the online manual for MultiPlus-II GX 5000Va. Victron Energy site only has the 3000Va download. Please help.
When setting up an AC coupled system with a Fronius PV inverter, the instructions state that the default Victron configuration is the correct one. However, I have found conflicting defaults and self contradicting documentation, so would like to clear the air on this and get a definitive answer on the correct settings.
On the Victron website there is a guide for setting up a Fronius inverter: https://www.victronenergy.com/live/ac_coupling:fronius#setting_up_the_victron_multi_or_quattro . This mentions that it is not necessary to change the defaults, and shows a screenshot of the settings and also a table:
However, as can be seen above, the setting for 50Hz are inconsistent between the picture and the table, with different start frequencies.
When configuring the system, I have tried both the ESS assistant and the PV Inverter assistant, and noticed they both have different defaults:
So when we are told that the defaults are fine, and there are different defaults depending on the assistant, and the documentation contradicts itself, it can be a bit confusing.
For what its worth, I believe the defaults in the PV Inverter assistant are correct (51Hz start) based on my discussions with Fronius, but I just want to check this with Victron and draw attention to it so that the assistant defaults and documentation can be updated.
The more one starts to dig around in Victron documentation, the more discrepancies pop up.
I'd strongly suggest to establish something like a central knowledge base a.k.a. "semantic vault" - similar to wikidata and to generate from there. One (of many) examples:
states a Quattro 48/10000 does weigh 45kg
speaks of 51kg. That's not what OCD'lers like me want to read. Moreover, said datasheet sugests that the Zero-Power of an 10kVA Quattro is the same like that of an 8kVA Quattro ... which looks unbelievable/also like an error.
I'm stumbling across this sort of errors all the time, and I do give feedback sometimes, but quite frankly: It's too much.
Has anybody got the dimensions (mm) indicated in the image?
Thanks in advance.
The manual page at: https://www.victronenergy.com/support-and-downloads/manuals is missing the Battery Balancer from the list.
WHERE IS DOCUMENTATION ONLINE REGARDING BMV-712 W/TEMP. SENS. AND SMART MPPT 100/50 SETTINGS AND HOW CONFIGURE PARAMETERS.
I have a new project for an off grid three-phase installation. As this is my first three-phase project, I am looking for informations, schematics on this subject. Could you direct me to the documentation on this subject? Thank you.
Can we include the text/hex protocol for the SmartSolar/BMV/Inverter documents on the Victron Professional collection?
It would be handy so I would always have the up-to-date documents. Plus I think it's actually the only thing missing.
I just received my Phoenix 12/1200 inverter and reading through the manual I found a contradiction. In the English section on page 2, Section 3, Installation; mounting the inverter there are 5 choices. Two choices are “not recommended”.
1) upside down on ceiling
4) vertical wall mount with fan up.
I want to mount the inverter horizontally on a vertical surface (choice 5 which is marked OK)
In page 2 of the Appendix there is a warning specifically to NOT mount the inverter horizontally on a wall, but mounting vertically on a wall is OK
So, what is the correct answer? I can also mount my inverter on top of a horizontal surface, but that is not optimal for my situation.
This is also true of the online manual from your website “ Version 00 June 15, 2017”
Can l set up the multiplus compact for lithium phosphate batteries with the DIP switches? If so how do I do it. I don't have the color control yet.
I was reading paper version manual for my BMV today, just to review my setting and try to learn more about it. But I got confuse cause I think there is contradicting information within. I had to go check the online version, to check if it was a typo that was maybe corrected. But I find the same error (!?) in the online version of the manual.
I'm saying this, but I might be wrong and confuse, please correct me if I'm wrong. I would really like to know which info is right or if the 2 info I think are contradicting are just 2 different info that I think should be the same..
so at 2.3 commons problems it is mentioned:
and when reading further, at 4.2.1 Battery settings under 02. Charged Voltage we found that:
and then if you just the mentioned section 3.7 (in blue ^) the mentioned voltage (13.2v) is proper for float and not for absorb, so think section 2.3 is wrong, unless I am just really confused and those 2 pieces of information are not related to each other...
so to add to my confusion, when I look at my own setup in the BMV, charged voltage is set to 14,8V, which I don't remember having set that, but I would really like to know if this is right or not
If ever i am proven to be wrong, i would like excuse myself in advance since english is not my first language
We probably took a lightning hit to the mast, Windex found embedded in cover, fresh burn on shore power nuetral pin.
Is there a service manual, TSG and parts store?
Is there anything on YouTube?
I have a Victron 75/15 controller with the Victron control/display that has small, circular (maybe 2 inch diameter) face with buttons to move through menus. Where can I get a description or map of the menus and their functions?
Hi. I am looking for the thd figures of inverters and could not see them in the datasheets. Many thanks
Hello Victron Community,
Along with the launch of the Victron Community, and the Victron Support page, I started a document last year to help users to help themselves before they contacted others for more support.
The beginnings of the document are here:
I would really appreciate some other peoples feedback or even contributions.
If you have a GitHub account, you should be able to edit it directly (with the link at the bottom)
Otherwise, I would welcome any suggestions or contributions in comments to this post.
Once it is good enough - it will be linked in Step 2 of the Victron Support page.
