48V or 51.2V LiFePO4

Not disagreeing with you, but did you do any of the online (free) training before starting your project?
Did you purchase online or use an experienced supplier who should be a source of guidance?
These systems are complex because they can be put together in so many ways, one of the reasons people choose Victron.
The number of DIY queries we get, and the owner did not even know there was an ESS guide, let alone full setup guides for each supported battery, yet there is so much easy to find information available, not considering the wealth of info this community and the archive holds.

I am not employed by Victron, there is a direct label for Victron Employees here i am sure you have seen it since you have had conversations directly with them. I have been installing solar (not just victron) and been in the industry for quite a while. Yes we use alot of the different Victron products.

I think you are implying here that there is some kind of malicious intent when there is not. And it is more of a starting point in configuration hence the general name. If it said pylontec and was incorrect then i would agree there is something that needs to be addressed.

And i will return to my point of - basic fundamentals of knowlege is not the responsibility of Victron.

There will always be a huge debate on how liefpo4 batteries should be charged. What voltage range etc. There are many debates on many forums so having one concrete answer is not possible. (As it is not a black and white subject.)

There are more than that so the next person would probably come along and ask why weren’t why catered for etc. it will end up being a full time job trying to vater for everyone, when you can just make it general and editable and then everyone can do what is right for their specific wants/needs in application.
For battery related care, you ask the battery manufacturer how they want their product to be treated, not an unrelated inverter manufacturer - this is why I am saying it is not Victrons responsibility here.

Warning labels are there on alot of products. Use and misuse there after is the responsibility of the end user. Some examples include prescription meds, alcohol, cigarettes etc.
Yet there are many who go right ahead and carry on and consequences are there. Still those consequences not the responsibility of the product or the company that made it.

Ignorance even of the laws of a country cannot be used as a defence in doing something that breaks them.
The same applies to solar, there are dangers and risks associated with it as with all electrical work, they don’t go away just because you didn’t know.

You seem intelligent and knowledgeable, which is why it’s surprising that you’re asking for information that’s readily available and explained in documentation. It feels less like a lack of understanding and more like a refusal to acknowledge what’s already been laid out. I’m not sure why this needs to be spoon-fed when the expectation is to take some initiative and responsibility. This would be the same for any endeavour undertaken whether it is your own qualification/job related.or even a small project a home or cooking a meal.

A post was split to a new topic: Is Victron documentation too complicated?

I’m not asking anything, I’m stating and showing information that is incorrect in the documents, and a default configuration option that doesn’t adequately say to which case it applies. The lack of respect and cordiality is in those who deny the existence of the error and say that Victron’s materials are only for trained professionals who know everything and who will understand that what the document is saying or the description of the default parameters option are not exactly what they say. And I think it’s important to put this issue here in this forum because, in addition to Victron being able to see and make corrections and improvements, it can help other people who had or could have some difficulty with this issue before discovering the fact that I’m sharing.

The standard LiFePO4 setup is 4 cells for 12V (12,8V), 8 for 24V (25,6V) and 16 for 48V (51,2V).
And that’s what the presets are for.

15S or 17S are not standard.
Victron can’t add suitable presets for all possible battery types.
You know what? There aren’t presets for Li-Ion, NMC, NCA, LTO, NiCd, NiMH… :open_mouth:

YOU as the installer have to look at the manual of your battery, check if the settings are correct and adjust them if needed.

All manuals clearly say that YOU as the installer are responsible for what YOU are doing.


But it looks like the manuals are need even more warnings.

There also is a list of officially supported batteries and recommended settings:
