October 21, 20232 yr Hi, I have 8x48074h pylontechs and have just put on a new SC1000 bms, I am pretty sure it is chipped with newer firmware than the batteries which are 2yrs old. It will start and then solid red light, I can blackstart it and it will run perfectly for the allotted 10min then drop the relay, has anyone had any experience of this or know anyone in Capetown or George that can assist please
