question

If I want to make changes and update firmware, without using bluetooth or internet on site, what do I do? This is all very confusing. There's VEconfigure (which sounds like I'm not ever supposed to use except in extreme circumstances), Victron Connect, the internal control (in my case Touch 50 and CerboGX). Am I missing another?

I'm not sure what each is for.

To complicate matters even more, I've got four Pylontech US3000 batteries I'm hooking up. These are LiFePo4 batteries with integrated BMS, but the Victron manual about compatibility is strange. https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom

Section 5 seems to be talking about the US2000 model, so it's not exactly clear. Is there an exact specification for how the US3000 is automatically pre-configured to run with the rest of my system (victron components)? Are the tables in section five the actual parameters (before making any modifications) or are is the article suggesting we use VEconfigure to change the parameters to the specs shown in the tables?

One thing that I noticed is the float voltage set at 51V. Is it a good idea float charging a LiFePo4? Shouldn't that parameter be lowered considerably?

I guess it's good that battery charging parameters "are automatically configured by the Pylontech BMU, and communicated to the rest of the Victron components in the system via DVCC." Supposedly the Pylontech would know what's best for the Pylontech, right? Does it ever turn into a conflict with what the Victron components want?

What is VE.direct? Is that another software program? Or is that the name of one of the cables?

The charge voltage in the US3000 manual gives the value 52.5-53.5V, so does 51V sound good to you for a recommended Float voltage?
