AC Sources
The inverter’s transfer relay is normally set to provide inverter power to the output. When an AC
source is connected and accepted, the internal transfer relay switches to transfer the AC source power
to the loads. (See the Operator’s Manual for the inverter’s acceptance criteria.)
Figure 11 Multiple AC Sources
The inverter has a single set of AC terminals which are intended to connect to a single AC source.
It cannot be directly wired to more than one AC source at the same time. If multiple sources are
used, it is usually required to have a selector switch that changes from one to the next. The switch
should be the type which disconnects from one source before contacting another. This prevents the
risk of connecting to two out-of-phase sources at the same time or connecting them to each other.
IMPORTANT:
When installing a generator, it is recommended to turn off the GFX inverter’s Sell feature.
See the system display manual for instructions.
