Thanks to the higher, 750 volt maximum DC input voltage, often times one less module string is needed because more modules can be switched on in a series.

• Highly flexible design reduces cabling requirements
• Maximum efficiency of 97 percent ensures top solar yield

Greater flexibility in planning, implementing and solar harvest: The advantages of multi-string technology in the new transformerless Sunny Boy are also available in the 3 kW model.

• Optimal yield in partial shading and efficient operation of east/west arrays
• Two MPP trackers with expandable OptiTrac^®* Global Peak operational control
