2.4 Working Principles
Conceptual Diagram
The SUN2000Lreceives inputs from up to two PV strings. Then the inputs are grouped into
two MPPT routes inside the SUN2000L to track the maximum power point of the PV strings.
The DC power is then converted into single-phase AC power through an inverter circuit.
Surge protection is supported on both the DC andAC sides.
