2.4 Working Principles
Conceptual Diagram
The SUN2000L receives two inputs from the two PV strings. Two MPPT circuits are
configured inside the SUN2000L. Each circuit tracks the maximum power point of one PV
string respectively.
The SUN2000L reserves a battery port to connect to batteries which are used to store the
surplus power produced by PV strings and not required by residential loads. The power stored
in batteries can be exported to the power grid based on the load condition to meet peak power
consumption requirements and maximize the benefits.
