dollarnaira:We had two Pylontech batteries catch on fire. And we still can tell why. Massive cell level failure 6 Likes |

chris81964: 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? 1 Like |

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. chris81964: 5 Likes |

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. ceaser: 2 Likes |

chris81964: 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. |
Re: Solar Energy, A Complement To FTA by ceaser: 8:04am On Aug 23, 2021 |
dollarnaira: 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. 2 Likes 1 Share |

Please help me for here o. Na someone tell me say a vendor sent him this and that he maintained that the capacities are NOT FAKE but true capacities. He said he gave him links of sellers that had fake capacities to compare. He was even angry at me for disagreeing with the seller's claim of true capacities. Na I'm í come dey look say these capacities claimed to be authentic are actually fake for a 12v Li-ion pack. Abeg make una help me look before I start to dey confuse myself.
