Can SmartSolar 100/50 be safely be switched off in order to install fuse for battery, and then start it again? To switch off: disconnect PV and the battery, and to start again in the reversed order.
That’s pretty much how the manual describes it. With the small addition of checking with a meter inbetween each stage on powering up again.
So Yes.
Thank you for quick reply. Good point that about a meter which I have at hand all the time.
