A solar power system is only as good as its inverter. Grid Inverters convert direct current from solar cells to grid-compliant alternating current (AC). All SMA grid inverter can be combined with SunnyIsland to power the AC-bus while energy flow is controlled by SunnyIsland. For single phase mini-grids SunnyBoy and Sunny Mini Central are recommended and for 3-phase systems all Tripowers. In combination with Multicluster big systems up to 300kW can be realised. TL = without transformer
A= with transformer.
