inverters with multi-MPP trackers, which mean they are ab le t o co nn ec t to d if fe rent
PV module arrays. The equipment may only be operated in compliance with its
intended use.

Grid-tied PV system Overview:

The in ve rt er ma y only be op er at ed wi th a pe rm an en t c on ne ct io n to th e p ub li c p ow er

risk of the operator.

As drawings shown above, a complete Grid-tied PV system consists of PV modules,
PV inverters, public grid and other components. Moreo ve r, PV inverters always act as
key components.

When design a PV system contains Grow at t UE s er ie s in ve rt er s or a ny o th er G ro wa tt
