Yes, thats pretty much all I want to do. Although the reseller was both helpful and kind to point out incompatibilities, it made me believe communication was more or less a necessity for this type BMS. I think I will take another look at that JK ? Sounds like it's a useful option to have...

Actually I'm not sure how important it really is. What options would I be missing out on?

Hello! Been looking to get a JK BMS but (according to reseller) there seems to be some compatibility issues with my inverters protection board and RS485 or CAN communication. How do I know what BMS to get? BMS My EPEVER NP300-22 inverter Batterybank 8x280ah LFP cells.

Is it really cheaper? Looking at 1 pc LFP 24V vs 2 pcs LFP 12V, the prices vary very little. It's likely you already got the batteries by now but if not, I can see no disadvantages with a single 24V.

Hi! I'm also new to solar so take anything I say with a bucket of salt. But, from what I understand, larger gauge wires is more or less required for 12V systems, so that should be fine. You just need to fuse accordingly to, wire, inverter load and battery type. I am a bit sceptical a 1500W...

It was the leads. I crimped on more proper lugs for better connection and now it works as it should. Just goes to show how important a good connection is :)

Thanks, that feels reassuring. I did make my own wires. But I will inspect them to see if they have become faulty somehow.

Thanks for your reply. I was careful not to touch the voltage. Everything looked ok and it dropped down to about 8.3 amps, but then slowly started rising to 8.6. I got worried so I turned the power supply off. Not sure what to do now, if it's damaged or not?

When top balancing individual cell is it normal for the amps to first drop down and then start increasing? Using a 10A 30V bench top power supply with a single 280Ah 3.2V cell. Could the cell be damaged?

8x280Ah battery is what I have. If my English phrasing is not the best is because it's not my first language. This was already mentioned in earlier posts, #9, #12.

Yes. A 225A fuse is out of the question then? Thanks, but I'm in Europe. Unfortunately that company does not ship international. I will have to look somewhere else. No, already have the 24V (LF) 3000W inverter and all plans is for that setup. Anything else was just me using theoretical...

Amazon I see they have a 160A holder, but only ignition protected version I don't need.

Ah, yes. Either way they both make sense, and 150A will be great. So, this is where I run into a bit of a problem. The fuse block (blue sea systems) I 'm looking to buy seem only to take 225A-400A fuses. Is perhaps 225A acceptable for 1/0awg? Sorry about that. It did help me understand things...

Good to know. From a newbie perspective mostly learning by watching videos it's very easy to underestimate how much just one component, i.e what battery chemistry is used, will affect a setup. Thanks for pointing this out to me. Think I dodged a bullet there. Yes, and, yes. Thanks. I got my...

Please help me make sure if I have understood this correcttly. Using a completely different example. 2X12V=24V (AGM), 2000W (HF) inverter, (MRBF) fuse. 2000W/.85//24=98A /.8=122.5A ≈ 125A. Minimum wire/fuse: 6AWG/125A (wire rating 115A max) Medium wire/fuse: 4AWG/150A (wire rating 150A...
