CAT 6 can also be UTP.

Pylontech batteries are rated the same way, but the BMS always reports the max discharge current at 0.5C - so most inverters will never go over this value.

Then I suggest monitoring individual cell voltages when that happens (with either PBMS tools, or this one: https://github.com/Tertiush/bmspace or solar assistant). I think it's likely a cell that is triggering an undervolt disconnect, but with the tools you should be able to see what the issue is. Actually, with PBMStools, you should just be able to look at the log and see what caused the previous disconnect.

Yes, you have to go to 100% often enough for the BMS to have a reference, otherwise drift like that is expected. It's also required to ensure balancing happens.

A small passive balancer is all you need over the long term - just look at any commercial battery. Not a single one of the big brands have anything more than that, the FreedomWon with the Orion BMS (ie not the eTower) has the highest I am aware of at 200mA.

Yes there is another thread on this topic: It's most likely that the inverter is outputting DC, which will cause fuses in things with transformers or induction motors to blow (or overheat and fail) without looking like a surge.

Seems like the OG 5.48 has a high voltage MPPT, so 2S panels will have too low voltage for the MPPT: I'm surprised it even does anything. If that is the case, you will have to put more panels in series.

Most RCDs don't have overload protection and HAVE to be used with an MCB.

Yeah, so the reasons stated in your article is the same for all forms of heating:

That seems unlikely - I sleep with the aircon on cooling 12 months of the year and don't have a hard time with it. I can't speak for others, though.

I don't see how an aircon on heat mode can dry things out. Heating air increases it's ability to hold moisture. In cooling mode it decreases it's ability to hold moisture, which makes the water condense, drying out the air.

Yes, only essential adds to overload.

That's because something is switching on and off that requires the battery to go from charge to discharge mode rapidly (where it stays for a while). If you have enough solar to cover that case, it should not do that, or if you remove the load that does that - looks like it might be a clothes iron going by the frequency?

I'm going to guess C...

The workaround is to tell the inverter it's 2xUS2000s. Have you tried that?

For reference, this is from the new 5048ES datasheet: Notice the same spec being 9200VA, but it won't allow passthrough of nearly that.

The spec sheet states this: "Max apparent power from utility grid" means that you can pass-through 5000VA, while charging the batteries with 5000VA. What is stated in the video does not reflect in the datasheet - the max AC output current seems to be 22.7A. If what they say in the video is true, then they should make it more apparent and also update the datasheet.

Only for 10 seconds - that's why.

I think there is possibly more than one issue. What voltage do you charge them to?

Wow, no BMS with incendiary cells, that is either very brave or something else...

Nominal voltage per cell is 3.2V for LFP. 51.2/3.2=???

Inverter outputs DC for a short period of time.

Most likely your 200mA fuse won't "POP" at all with 220mA applied, and if it does it will take a while. (the 200mA fuse curve never even crosses the 300mA line...)

This is only true if the power supply is a switch mode. Since it is stated that this affects devices with (lf) transformers, it's much more likely that they have linear PSUs which makes your theory fall on it's face...

How did you get to that conclusion?
