Electrical Specifications
975-0131-01-01 A–3
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.
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.
