Hey guys
I hooked up my 11 panel string to my Growatt SPH 6000 and it is running fine but i happened to touch the aluminium ladder and then the steel frame, got a strong tingle in my hand so i got my multimeter out and read 38V AC coming from the steel frame.
I haven't grounded the array just yet but this is only happening when the inverter is using battery power and the arrays not making any power.
I'm really confused on how theres AC voltage on the solar panel frame and would really appreciate any help on this.
Many thanks
