Hello,
I've installed 2 x Growatt SPF 5000 ES (I live in Europe) in parallel and a very annoying problem I'm now facing is that they occasionally trigger the upstream RCBO (the residual current component not the over current one) fitted by the utility company.
I am confident it's not because...
As I was changing the leads for the BMS I managed to rip off 2 electrical components and also lost them in the process. Since the BMS was disconnected it's not burnt so I would like to try and solder them back but I don't know what they are.
Yes, I know it's dumb... As an excuse the newer...
