Overview
The SMA Sunny Boy 3.0 Inverter is a single-phase grid-tied solar inverter from SMA with 3 kW of rated AC power. It connects at 220 V AC, the most common low-voltage service in Brazil. It accepts 2 PV strings.
In Brazilian distributed generation, the DC/AC ratio (array power over inverter power) is usually kept between 1.0 and 1.3, and the inverter needs a valid INMETRO registration to be accepted in the utility's grid-connection request.
