The new Sunny Boy 1.5 and 2.5 inverters are the ideal solution for small photovoltaic installations.

Easy to set up, the inverter is compatible with a wide range of photovoltaic panels thanks to its extended voltage range (80 - 600V) which makes it very flexible while displaying excellent performance.

Small in size, it is also particularly light. It fits easily indoors or outdoors

The installation is easy both indoors and outdoors thanks to its sturdy and lightweight case, ideal for small photovoltaic installations.

Optitrac technology

Optitrac technology


OptiTrac Global Peak is an additional feature of the proven "OptiTrac" MPP tracker and is activated on this inverter

This is used in the case of partially shaded photovoltaic installations. Even in this configuration, this special operating mode ensures the panels operate continuously at the maximum power point, with no significant impact on performance (loss < 0.2%). Aurement says: even in case of shading the panels work properly.
