AC Configurations
Single-Inverter
Figure 26 (below) shows the general wiring of the Radian inverter and the AC system connected to
it. This figure is not a physical representation of the inverter and does not depict the GSLC.
Figure 27 (see next page) shows the locations of AC and network connections. It is a physical
diagram for wiring the GSLC, network components, and external AC devices with the inverter.

All overcurrent devices in permanent installations must be sized for 50 Aac or less.

All output wiring and circuit breakers must be sized appropriately for loads and inverter power.

The inverter has wiring connections for two AC sources, but it can only accept one source at a time.
Figure 26 Single-Inverter AC System
1. The Radian inverter has separate neutral connections for grid input, generator input, and output. These are electrically
common. If an external neutral bus exists (as shown in the AC Load Panel above), not all of the Radian neutral connections
need to be made.
2. Maintenance bypass switching assemblies are commonly used so that the inverter can be taken offline, if necessary, without
shutting down the entire system. These assemblies usually include an interlock mechanism that isolates AC lines from each
other. This figure shows the general design of a bypass system.
