Fronius. Premiums Premium.

Fronius inverters are brilliant: reliable, high performance with a very smart optimisation algorithm to squeeze lots of energy from panels even with partial shade or on multiple roof areas. However. It is important to note that marketing aside they perform blow for blow with other higher end inverters like Redback Fairly reliably, and for a higher cost to boot, with a seemingly higher failure rate (From our experience) 

Fronius is a great statement piece. And sure to turn any solar aware heads tho.
