Every time i hook up my makeskyblue 60 amp solar charge controller to my 250 amp dally bms it sparks. The bms turns on and everything seems ok, but i heard that sparking is bad.
I have tried pre charging it with a resistor to no avail. The machine shuts off seconds later and then sparks again.
Is this intended behavior?
What do i do to stop it?
The charge controller and battery seem to tollerate it, with no warning tripping from the bms and no breaking from either one.
Edit:
Will it make a spark when connecting panels too? How to stop that?
