4 Product Description
The Sunny Boy is a multi-string inverter that has two input areas, A and B, each with its own
MPP tracker. This continually determines the maximum power point and controls the voltage on the
PV modules accordingly. The two separate MPP trackers make it possible to connect different
PV strings to input areas A and B. The PV strings may vary in the number of PV modules, their
orientation to the sun and shading.
