Manual/Schematic for "ancient" Atlas 24/1200?

I got an old unused Atlas 24/1200 inverter without documents for free and have been looking all over for a manual/schematic for it. I know it's efficiency and power quality is probably the worst compared to recent models, but for the usage I'm looking to use it, there win't be any problem. Anyone have a file somewhere, I checked the Victron Dropbox but can't find anything for this particular model.


Here is a picture of it, just to understand how old it is.

Feature Request / Documentation Enhancement

Please place the "http://www.victronenergy.com/upload/documents/manual-VE.Bus-firmware-versions-explained-EN.pdf" file into the proper directory in dropbox for use during upgrades in the field.


Background/repro steps:

  1. Firmware on the pro site can be linked via Dropbox to my local computer via this site: Connect with Dropbox - Victron Professional (victronenergy.com)
    1. This allows for easy upgrades when I am at a site with no internet connectivity.
  2. Firmware updates and the decision tree for VE devices can sometimes be tricky with references to chip versions etc.
  3. Firmware versions are listed here:
  4. Dropbox/Apps/VictronEnergyCMSSync/Firmwares/VE.Bus (Multis, Inverters and Quattros)/VEBus firmware numbers.txt
    1. This document wisely tells you to reference http://www.victronenergy.com/upload/documents/manual-VE.Bus-firmware-versions-explained-EN.pdf
  5. If I am at a remote site I have NO access to the Internet so I have no access to this reference material.
  6. I do not want a local copy on my hard drive.
    1. This document may change.
    2. I use dropbox as a single source of truth regarding Victron firmwares for VE Devices.
  7. I do not want to ask my customer to remove panels to give me information regarding chipset etc.
    1. This could be dangerous.

Thank you for the consideration

Victron API

Hello people,

I noticed that Victron updated the API documentation web site. The weird thing is that they removed the ArttibutesCode list from the documentation and I could not be able to find it anywhere. Does anyone have the previous API documentation file? If so, Could you please shared it?

Recommended Fuse Size Missing from MultiPlus 500VA - 1600VA Manual

I've just been reading the Wiring Unlimited document and in section 4.1 it states:

[image]

Though this does not appear to be in the Rev 06 MultiPlus 500VA - 1600VA Manual:

[image]

I've scoured the document for "recommended", "fuse size" etc and cannot find any references for this for any of the models

Is there a reason why these are excluded from the manual here as I'm missing or misunderstanding something?

Specifically I'm looking for the 12/500/20 recommended fuse size if someone knows that in the meantime.


Thanks.

THD (Total Harmonics Distortion) vs Power reserve

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?

Thank you.

Typo in BMS 12/200 Documentation

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.

Inconsistent frequency shifting documentation - correct Fronius defaults?

Hi,


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:

[image]

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:

[image]

[image]


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.


Thank you,


Richard

Discrepancies in Technical Specifications

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:

https://www.victronenergy.com/media/pricelist/WEB_WithoutIP65_PricelistVictron2020-Q1.pdf

states a Quattro 48/10000 does weigh 45kg

https://www.victronenergy.com/upload/documents/Datasheet-Quattro-3kVA-15kVA-EN.pdf

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.
