I dove into that thread and when he mentioned Tesla modules and a default configuration I suspected the reason was overvolting the batteries. Tesla modules are a unique voltage that do not fit many default settings. The nominal voltage is 22.8 which is easily overvolted on any typical 24 volt default setting.
I went thru it too, it was a Tesla module and he stated the MPP6048 would not hold the custom settings.
He should have not been using it to charge the Tesla module, it's that simple.
I also assume no BMS which if set properly could have stopped the disaster before the battery got hot.
He was asked about a BMS, it seems to have been ignored. When that occurs, the usual correct answer is there wasn't a BMS.
I do not know for sure that is what happened but I have seen too many reports of Tesla modules being abused to not suspect that was the case.
After going thru the post, my conclusion is the same. It is a case of someone not knowing what they were doing and not employing proper safety measures including a BMS.
I did not see any statements that concluded it was the MPP charge controller.
It is like the original post of this thread, it was insinuated. While I do have some respect for the OP of this thread, the insinuation tarnished that respect.
I'm not defending MPP by any means. But to claim it was the MPP unit that was the cause is not really correct. It is multiple errors I see in the thread on FB. Ignorance on display I guess.
Yes, all could have been prevented with much better choices made by the person who installed the system.What a shame.
