I have just installed a multiplus 24/3000/70 that I think was one of three in parallel with the previous owner.
I cannot connect using MK2 usb adapter.
I have a compact 24/1200 inverter, and this connects straight away, but when I plug in to the 24/3000 it is not found, so cables and MK2 are ok.
Any help would be appreciated.
Regards
Edward
