The new 1.5 and 2.5 Sunny Boy inverter are ideal for small photovoltaic installations.

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

white its small dimensions and very lightweight, it integrates easily everywhere.

Performance curve



Optitrac de SMA


OptiTrac Global Peak is an additional function of the MPP tracker for operation in partially-shaded PV plants.

This specialized operation management system ensures that the modules are constantly operated at the point of maxi- mum power even when there are multiple maximum power points (in the case of photovoltaic systems partially shaded), without causing measurable yield loss (loss < 0.2 percent). In other words, even if the shading panels work properly.
