Surge Performance
Unlike many other inverters, the Conext XW Pro helps stop voltage from sagging
dramatically during surge conditions. The Conext XW Pro handles surges of over twice
its rated output power with only a minimal drop in output voltage for limited periods of
time.
Islanding Protection
Islanding protection is an essential safety feature that helps reduce harm to those
working on the utility grid from a distributed energy source such as the Conext XW Pro.
Islanding protection also helps to prevent loads connected to the Conext XW Pro from
being damaged by a fluctuating utility grid input. The Conext XW Pro uses proprietary
positive feedback control to achieve anti-islanding operation while maintaining low total
harmonic distortion at the grid connection. Default software settings are programmed into
each Conext XW Pro at the factory so that they comply with applicable safety
regulations (such as IEEE 1547 and UL 1741 in North America).
In some instances it may be desirable from both a utility and a customer point of view to
adjust the default anti-islanding settings. For example, the Conext XW Pro may
experience “nuisance trips” if the grid is weak and the voltage falls outside the allowable
range specified by regulations. It may be difficult for a utility to adjust the grid to stop this
problem. With permission from the utility, the factory settings may be changed to allow
the Conext XW Pro to operate over a wider grid voltage range. These settings must only
be changed by qualified service personnel using either Conext Gateway or a special
software application (Conext XW Pro Configuration Tool, Order # 865-1155-01) provided
by the manufacturer.
While exporting energy, the Conext XW Pro continuously monitors the utility grid voltage
and frequency. If the grid voltage or frequency move beyond the Conext XW Pro default
ranges (for example, during a power surge or outage) the Conext XW Pro stops exporting
energy through AC1 and disconnects from the utility. If disconnected due to a grid
voltage disturbance, five minutes is the non-adjustable minimum reconnect time during
which the Conext XW Pro does not export energy through AC1 to the grid. The Event
LEDon the Conext XW Pro information panel will indicate a utility fault. No fault code
appears on the three-character display because the fault is with the utility grid, not with
the Conext XW Pro.
In addition to the information panel, the Conext Gateway web application indicates any
utility faults with details present under all affected instances of Conext XW Pro. The
faults cannot be manually cleared. Utility faults will clear automatically when the utility
grid voltage and frequency return to within the ranges programmed into the Conext XW
Pro. If grid support is enabled and the utility voltage and frequency come back within
tolerance, the Conext XW Pro information panel displays a countdown timer for five
minutes until the Conext XW Pro can start interacting with the grid again.
