Electrical Specifications
Adjustable Disconnect SettingsIslanding protection is an essential safety feature that ensures no person working on the grid is harmed by a distributed energy source. Default software settings are programmed into each GT Inverter at the factory to ensure it does not island according to relevant safety regulations (VDE 0126, RD 1663/2000).
In some instances it may be desirable from both a utility and customer point of view to adjust these default settings. For example, the GT Inverter may experience “nuisance trips” (taking the inverter “offline”) if the grid is weak and the voltage falls outside the allowable range specified in the regulations. It may be difficult for a utility to upgrade the grid to eliminate this problem. With permission from the utility, the factory settings may be changed to allow the GT inverter to operate over a wider grid voltage range.
These settings are password protected and should only be changed by qualified service personnel, using a special software application provided by Xantrex. Changing any values may compromise compliance with safety regulations. Do not do so without first consulting with the utility and agreeing on acceptable settings.
The default values of these settings differ from the utility specifications on page
Note: Disconnect settings on German models are not adjustable.
