2.4 Working Principles

Conceptual Diagram
The SUN2000L receives two in puts 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 DC power is then converted into single-phase AC power through an
inverter circuit. Surge protection is supported on both the DC and AC sides.
The SUN2000L has a reserved 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 and
valley power consumption requirements and maximize the benefits.
