Xantrex Technology GT3.0 Adjustable Disconnect Settings, Output Power Versus Ambient Temperature

Electrical Specifications

Adjustable Disconnect Settings

The adjustable disconnect setting values vary depending on whether the inverter is a 208 Vac/60 Hz, 240 Vac/60 Hz, or 230 Vac/50 Hz model. Utility permission is required prior to changing the settings on the inverter.

The default values of these settings differ from the utility specifications on page A–2. These differences take into account the accuracy ranges listed in the table below, and are intended to ensure that utility specifications are always met.

		Default Values		Adjustment Range
Setting
	208 Vac/60 Hz	240 Vac/60 Hz	230 Vac/50 Hz	From...	To...	Accuracy
AC Low Voltage	186 Vac	214 Vac	205 Vac	180 Vac	269 Vac	+/– 3 Vac
AC High Voltage	225 Vac	261 Vac	250 Vac
AC Low Frequency	59.4 Hz		47.1 Hz	46.0 Hz	62.0 Hz	+/– 0.1 Hz
AC High Frequency	60.4 Hz		50.9 Hz
Reconnect Delay		305 sec.		60 sec.	600 sec.	+/– 5 sec.

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.
