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.
3. When multiple inverters are stacked, the GS Load Center (GSLC) for each inverter can be wired together to serve as a
common input conduit box and AC load center. However, the GSLC bypass switching assemblies are only sized for single
inverters and cannot work in conjunction with each other. The GSLC bypass assemblies should not be used with multiple
inverters present. (See page 15.) An external bypass assembly must be used instead. Larger external assemblies are
available from other manufacturers.
