Conext XW PRO 6848 6,800W 48V Installation

Problem Possible cause Solution(s)
The inverter connects to
the grid and can charge
normally. In a grid
interactive mode (Grid
Support enabled), the unit
is experiencing excessive
anti-islanding faults during
periods of high sell
amperage.
The impedance of the AC connection to the
inverter is too high for the power being sold
to the grid. The impedance may be on the
high end if the installation is too far from the
utility point of common connection or if the
wires are too small between the Conext XW
Pro and the main service panel.
Measure the grid voltage at the service panel
(meter base). It is important to measure L1-N, L2-
N, L1-L2, and N-Ground. If these measurements
are not within the voltage range for sell mode
(see "Electrical Specifications" on page122),
contact your utility for resolution. If these
measurements are within the voltage range for
sell mode (see "Electrical Specifications" on
page122), the most likely event is that the AC
wiring between the inverter and the meter base is
not sized appropriately. It should be sized for a
1to 1.5% maximum voltage drop. Alternately, the
Max Sell Amps can be reduced until the unit
stops disconnecting.
