  • Page 22: Working Principles

    Surge protection is supported on both the DC and AC sides. The SUN2000 uses a battery port to connect to batteries which are used to store the surplus power produced by PV strings and not required by local loads. To meet peak power consumption requirements and maximize benefits, the power stored in batteries can be exported to the power grid based on the load condition.
  • Page 23 Operating In Operating mode:  The SUN2000 converts DC power from PV strings into AC power and feeds the power to the power grid.  The SUN2000 controls optimizers to track the maximum power point to maximize the PV string output.
