IMPORTANT:
If multiple Radian inverters are stacked in a single system, these devices cannot
be used. The bypass function must be simultaneous for all inverters. The GSLC
bypass kits operate independently, not simultaneously.
In a new system with multiple Radian inverters, the basic GSLC should be used in conjunction
with an external assembly of this kind, as shown in Figure 41. The GS-IOB kits should not be
installed, or if previously installed, should be removed and all wires disconnected.
OutBack does not offer a solution for bypassing multiple inverters. However, electrical suppliers
offer both manual and automatic double-pole, double-throw bypass switches in a range of sizes
and options. These are highly recommended for systems larger than a single inverter.
WARNING: Shock Hazard or Equipment Damage
Using independent bypass devices on multiple inverters can result in power
being routed to inappropriate places. This could lead to an electric shock or
to equipment damage.
