    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.

  • Page 22: Working Modes

    Operating In Operating mode:  The SUN2000L converts DC power from PV strings into AC power and feeds the energy to the power grid.  The SUN2000L tracks the maximum power point to maximize the PV string output.
  • Page 23 Description Mode Shutdown  In Standby or Operating mode, the SUN2000L enters Shutdown mode after detecting a fault or shutdown command.  In Shutdown mode, the SUN2000L enters Standby mode after detecting a startup command or that the fault is rectified.

  • Page 24: Storage

    Keep the storage temperature at –40° C to +70° C and the humidity at 5%–95% RH.   The SUN2000L should be stored in a clean and dry place and be protected from dust and water vapor corrosion.  A maximum of 10 SUN2000Ls can be stacked. To avoid personal injury or device damage, stack SUN2000Ls with caution to prevent them from falling over.
