The MultiPlus-II combines the functions of the MultiPlus and the MultiGrid.
It has all the features of the MultiPlus, plus an external current transformer option to implement PowerControl and PowerAssist and to optimize self-consumption with external current sensing (max. 32A). 
It also has all the features of the MultiGrid with built-in anti-islanding and an increasingly long list of country approvals.

Note: for a short period of time this product was called MultiGrid-II.
