Multiple-Inverter Installations (Stacking Inverters)
When multiple Radian inverters are stacked for additional power, the basic wiring is repeated for each
inverter. However, several factors need to be considered.
 One GSLC is required for each Radian inverter. A single GSLC cannot be sized to handle the requisite current
for multiple Radian inverters.
 If more than two Radian inverters are installed, it is recommended to install a separate distribution panel to
distribute incoming power to each GSLC individually. It may be advisable to install separate AC distribution
panels to distribute input and output power to each GSLC.
 The GSLC maintenance bypass assemblies cannot be used when more than one Radian inverter is stacked.
See the next section.
Bypass Switches
Inverter systems are often equipped with maintenance bypass switches or interlocks. If the inverter
system ever needs to be shut down or removed, its AC sources and loads must be disconnected. A
bypass device allows the AC source to “bypass” the inverter and deliver power directly to the loads.
This can minimize disruption to the system and it avoids the need for extensive rewiring.
WARNING: Shock Hazard or Equipment Damage
 Bypassing multiple sources will usually connect the sources to each other, which may
damage one or both sources. It can otherwise result in power being routed to
inappropriate places.
 The bypass assembly does not disconnect the inverter’s AC input. Even with the
inverter bypassed, any AC input source may be a shock hazard unless disconnected.
To wire the GS-IOB-230VAC
after installation:
1. On the disconnect for the AC
source that will be used during
bypass, install a wire from the
left side as shown by
1 .
Connect it to the input bypass
switch as shown by
2 .
2. Install a wire on the right side of
the input bypass switch as
shown by
3 . Connect it to the
right side of the output switch
as shown by
4 .
