Conext XW PRO 6848 6,800W 48V Installation

configured will adopt a 60 Hz nominal grid frequency. Selecting IEEE 1547-2003 50Hz
will similarly configure a 50 Hz nominal grid frequency. All frequency-related functions,
including over/underfrequency detection, are based upon these settings. Refer to
"Managing Compliance Regions" on page99 for information on how to select a
compliance region.
Grid Support Settings
The Grid Support Settings menu contains configuration options for grid-tie
operation. To enable these settings, Grid Support must be enabled in the Grid
Support menu. Individual grid-interactive features such as PLS and Sell are enabled
individually.
In grid support mode, the Conext XW Pro supports the utility grid by limiting the power
drawn from the utility to close to zero. This mode is desirable for using excess energy
from auxiliary DC sources like PV, while still maintaining a charged battery bank. No
power is sold to the utility in this mode.
NOTE: Grid support and sell functions are modes of operation that are subject to local
and/or national grid interconnection requirements in most jurisdictions. It is the
responsibility of the installer and system operator to ensure that all applicable procedures
and technical requirements are complied with before turning on either of these modes.
The interconnect codes and standards with which the Conext XW Pro complies are listed
in "Regulatory Approvals" on page129.
NOTE: Upon startup, the Conext XW Pro does not enable grid support functions for five
minutes (300 seconds). During this period the Conext XW Pro connects to AC input and
determines whether the utility grid voltage and frequency are stable and within nominal
range. If Grid Support is enabled, the inverter information panel also displays a 300
second countdown during this period. For more information, see"Islanding Protection" on
page27.
NOTE: In grid support mode, the Conext XW Pro should not draw a large amount of
current from the grid. If the Conext XW Pro is drawing more than expected, it is important
to note that it cannot distinguish between real power and reactive power. Large current
draw will only affect reactive power and not real power, and utility companies generally
only charge by real power consumed.
