The AC Hot Out terminal connects to the load panel. It can carry up to 30 amps using the inverter’s transfer relay. Use the inverter wattage to determine actual maximum load. Size the breakers accordingly.
The AC Hot In terminal brings power from the AC source. It powers both battery charger and loads. Use the source amperage to determine actual maximum draw. Size the breakers accordingly.
The two Neutral terminals are electrically common. Use only one terminal if connecting to an external neutral bus. (An external bus is often placed in the main electrical panel, which is the Loads panel shown in Figure 11). Use the other terminal if connecting to a device with its own neutral wire, such as a generator.

All system wiring must comply with national and local codes and regulations.
Multiple AC Sources
It is usually required to have a selector switch that changes between multiple AC sources. The switch should be the type which disconnects from one source before contacting another. This prevents the risk of connecting to two

IMPORTANT:
When installing a generator, it is recommended to turn off the GFX inverter’s Sell feature. See the system display manual for instructions.
