Totally flat Pylontech battery. Can it be recovered? Part 2

[@fredflintstone1428]

Really excellent video and congrats on getting them working.

[@nicholashowell]

Thanks a lot.

[@Tnarius]

Great to see it's all working, glad the Tx/Rx swap fixed that bit of the puzzle so easily!

[@nicholashowell]

Yeah, I've had that issue before so I thought it might be that.

[@mick.Walker]

That sir is indeed a win, well done

[@kevinmatthews2620]

excellent, the comment "i havent done anything its working" was in part due to the battery sensing turning on of camera for filming :) :)

[@gavbansal967]

Nice job, thank you for sharing. Its people like you who give the rest of us the confidence and knowledge to try this out ourselves, just in case we get a fault. I'll google the pylontech battery view software and see if I can get hold of a copy. Like yourself, I have a few pylontechs. How would you go about monitoring each battery with a arduino/pi? I guess you'd need the pylontech interrogation software protocols first?

[@nicholashowell]

Yes, I'm working on this now. I'll make a video about it when I get it working.

Were you able to find the best settings for all the mppt charge controller parameters, for your packs?

[@michaeldepodesta001]

Congratulations: inspirational sleuthing!

[@laurentcnc6662]

Great Job !

Some/all Sofar Inverters have "Advanced Settings / 7. Battery Active". "Inverter can activate flat batteries when needed".

Good work 🎉

[@nicholashowell]

Thank you! Cheers!

[@kensteeplejack]

very useful information thanks.

[@nicholashowell]

Glad it was helpful!

[@BoB-Dobbs_leaning-left]

I can't find that Battery View software anywhere on their site. Anuone have any clues as to how to find it?

[@nicholashowell]

Send an email to [e-mail] and they can provide it.

[@BoB-Dobbs_leaning-left]

@nicholashowell I found it in the end. That USB to rj45 looked useful. so I tried it. For a start, windoze 11 doesn't seem to want to recognize com3, even though I installed it as per MS instructions. Wouldn't it need a serial converter? it gives me no choice between rs 232 and rs 485, which, I believe is the protocol it needs. Any ideas?

[@BoB-Dobbs_leaning-left]

@@nicholashowell The US3000c uses an RJ45 for the "Console" port. How does that effect the USB interface cable? the protocol is still rs232. Wouldnt it need a Serial / USB converter? The pinouts look very similar to the old serial crossover cable, as does your construction. Cheers.

Thank you for your video. The pack still has the bulge?

[@nicholashowell]

This pack didn't have a bulge. All the cells were fine and it is still working perfectly.

[@kbenergy7786]

Mine is us3000c but the circuit board has burnt capacitors

[@nicholashowell]

Not sure there is a lot you can do about that yourself. If it's still under warranty then you can probably get it fixed that way.

[@dopiaza2006]

The Capacity reading shows the current capacity as in charge level. It's rather confusing wording.

[@kbenergy7786]

Am confused on how to bring it back to life

[@mengezimabuya]

Confused as well
