Output Power Versus Ambient Temperature

Adjustable Voltage, Frequency and Reconnection Settings

Utility disconnect settings can be adjusted using the GTConfigLite software tool. Permission of the utility must be granted before adjusting any of these settings.

For more information about installing and using GTConfigLite, see the GTConfigLite User’s Guide (p/n 976-0260-01-01), available on the software CD.

Output Power Versus Ambient Temperature

Once the heat sink on the inverter reaches a maximum temperature limit, the GT Inverter reduces its energy output to ensure maximum component ratings are not exceeded.
