I am about to buy the smartsolar 100/30 SCC, but wanted to confirm the latest model. I am seeing the same device listed in various places, some have larger, black wire terminals on the front. Can you confirm if these are the latest model? If not, how is it possible to tell the age of the unit before purchasing, as a friend bought a new Victron item, but found it to be manufactured in 2016, and had been sat on a shop shelf ever since...
