We had two Pylontech batteries catch on fire. And we still can tell why. Massive cell level failure

Waoh. What could have been responsible? Cos even DIY LFPs on this forum haven't reported fire incidents. I had a little 18650 fire incidence a fairly long time ago from my negligence though but it was a small pack (4s16p). But peeps here with more massive 18650 packs have gone by without fire problems.

Pylontech isn't Li-ion, is it? We're the two units in one installation site or different sites? I think you really need to conclude investigations on this incident to have proper closure and know what and what not to avoid in its use. Cos even less professional level packs in huge banks have apparently been doing fine. I have not even heard any such incidences with Felicity. But Pylontech? Mhen!

@ Oga nìyí ìs pylontech user for a number of installations. What d'you think may have happened?

saint2ace practically chased me from the thread when I mentioned this.

GeorgeD1:


bro, its a bit gratifying to know you were on my side 2 or 3 years ago but i really don't think its about taking sides.
and if we should really take sides i think we should always be on the winning side. and, for me the winning side will
be the side that works/performs without stress.
i don't know what formula you used to derive your calculation which makes 2v 2000ah equal to 3.2v 280ah but i can
assure you there's nothing frightening about the size of my battery bank. a lot of effort was put into arriving at a
right size bank for my household needs and when the opportunity came knocking i gave it all i could muster and like
they say, the rest is history.
not everyone has the constraints of space and not everyone bothers about weight so what might be a show stopper
for you might just be a walk in the park for another person.
like i said before, lets leave all the options open and keep a balanced thread. lead acid will be with us for a long time
to come even as lithium continues to gain acceptance.

well said chief...

It would be great if you are able to share the outcome of root cause analysis for the Pylontech issues you experienced as soon as that information becomes available.

NiyiOmoIyunade:
Please believe that there is no innuendo or sarcasm here but by your own accounting on your youtube channel you have had installs of various products catch on fire and ruined a number of battery brands.

In recent memory, I recall you had trouble with Deye inverters bricked, Nissan leaf swollen and Weco batteries ruined with the root causes 'to be determined'.

These issues, fires, failures may have nothing to do with the products themselves but with the deployment methods used or the demands placed on the products.

If you are able to share the root cause analysis results for the Pylontech issues or another fire incident then this would be very good.

Boss, na good lawyer you be oo

Pylontech is LFP to be clear Lithium ion phosphate which is a relatively stable chemistry.

In several 100s of units we have installed or supported, I have not heard of or experienced any failures, I am not even talking about catching fire but I mean zero failures or returns. I know some dealers and installers too and not heard any report this failure mode.

On the foreign forums I have read of lightning hits and surges taking out the electronics in the battery and people welding contacts when they used too few batteries with too large of an inverter (due to the inverter startup inrush current) or load.

Oga Chris is best placed to give further insights into the batteries and what befell them.

Go online u will see Lead acids on fire. I have client who installed his lead acids in a generator house for fear of "in case of in cacity". Is like avoiding to drive a car just bc a neighbour's car had an accident.

In fact I intended to mention that of lead acid catching fires too earlier on but it skipped my mind. So catching fires is not the exclusivity of lithium chemistries. However my short stint with that 18650 fire made me know that it's not in the leagues of LA fires. It is potentially incendiary and putting out the fire may be the hardest (I think it is a class III - class three- fire which typically defies water and even the common fire extinguishers). That of lead acid isn't so common but not desirable nonetheless and the fact that it is related to the hydrogen gas produced from the vent brings some relief. I hammer it into the ears of clients, most of which are basically naive, that no naked flames near the batteries.

Even one was hell bent on having her tubular installed inside the cramped passage of her house. Being my street neighbour, I know some of her negligent attitudes so I explained why I am seriously uncomfortable with her suggestion leaving out that part about my observation. That I did pro bono installation for her doesn't mean she won't be breathing down my neck for setting her own house on fire. Of course I prevailed upon her to use LFP and still had it installed in her verandah with adequate ventilation.

What gives me some rest of mind regarding 18650 is its use in many commercially available battery packs like MTN lumous and BB jump thingy. And there has been no accidents with such widespread deployment. So once you do the connections right, the ills are avoided. If I have to use 18650s, the BMS must have temperature probes and use of resistor fuses is sacrosanct. In one instance like that I accidentally shorted a bank while connecting the wires, all those resistor fuses to that side burnt. Such relief.

I need it to be portable and also rugged. The total weight of the contents is around 14kg. Does yours come with a handle so it can easily moved around?

Came across this David Poz' link. He used beer crate. I think coca cola crate can fit into your application too with maybe a few modifications.

Oh. I see

You know for 9ja, fresh milk is a rarity. So when you hear crate, what comes to mind first is beer or soft drink.

Fresh milk plenty for north na is that not what is used for wara? Coca-Cola, beer crates should suffice

i couldn't have said it better. and for someone not trying to offload any solar wares to prospective clients, that
says a lot.
and like someone said in a previous message we been through all this lithium vs lead thingy a while back so i'm
not really going to do a repeat. lithium is still evolving and going mainstream by the day and for a long time to
come will be just another option besides lead acid. let us take that into account as we dissect info on this thread
so that newbies planning to take the renewables route would not necessarily get the idea that one option is evil
and to be avoided at all cost while the other option is good and to be embraced regardless of the cost.
balance of info is key here to avoid peeps being led astray.

Wise words from the Bossman himself.. Gracias !

Harvest is terible this week never saw so much overcasted clouds like this week

in other news does anybody knows who can repair an inverter Generator? need help ASAP thanks
