The GS Load Center (GSLC) is a wiring and circuit-protection enclosure that mounts under the Radian inverter. It is available in multiple versions:
The base GSLC includes positive and negative main inverter busbars, a 500 A 50 mV shunt with negative terminal bar, the main DC positive breaker plate, ground and neutral terminal bars, and two PV-positive terminal bars. It can also accommodate up to 18 AC or DC panel-mount breakers (ten top, eight bottom), two main 175 A DC breakers and a FLEXnetDC, which can be purchased separately. Up to two charge controllers can mount on the right side (mounting brackets sold separately), and either the HUB4 or HUB10 can mount on the left side.
The GSLC175-120/240 includes the base unit plus two 175 A DC main breakers, an AC output and bypass breakers with interlock plate, AC grid and generator-input breakers (50 A two-pole), and six AC terminal bars (three black, three red). It can also accommodate ten additional panel-mount breakers, (purchased separately).
The GSLC175-PV-120/240 works with the GS8048A or GS4048A inverter and two 150 volt charge controllers like the FM60 and FM80, and includes items in the 175-120/240 unit plus two 80 A PV array breakers, a two-pole GFDI 80 A breaker, three 500 A 50 mV shunts with shunt bus, and a FLEXnetDC. The GFDI acts as the breaker between the control and positive bus; there are no other breakers added for this purpose. It can also accommodate five additional panel-mount breakers, (purchased separately).
The GSLC175-PV-300VDC works with the GS8048A or GS4048A inverter and two 300 volt charge controllers like the FM100, and includes items in the 175-120/240 unit plus two PV array breakers, three 500 A 50 mV shunts with shunt bus, and a FLEXnetDC. The GFDI is built into the FM100 charge control.
The GSLC175-PV1-120/240 works ONLY with the GS4048A inverter and one 150 volt charge control, and includes one 175 ADC main breaker plus one 80 A PV breaker, one two-pole GFDI 80 A breaker, two 500 A 50 mV shunts with shunt bus, and a FLEXnetDC.
The GSLC175-PV1-300VDC works ONLY with the GS4048A-01, and one FM100 charge control. It includes one 175 ADC main breakers plus one PV breakers, two 500 A 50 mV shunts with shunt bus, and a FLEXnetDC. The GFDI is built into the FM100 charge control.
The AC bypass assembly is only for use with a single Radian inverter. For multiple inverters, use the base GSLC with added DC and AC breakers as needed (no bypass) and use external transfer switches for bypass and external AC load centers for output combining and input distribution. One GSLC is required for each Radian inverter. Each 8 kW inverter requires two 175 A main DC breakers and each 4 kW inverter requires one.
The GSLC is not rated for outdoor use. Dimensions are 17"H x 16"W x 8.5"D. Weight is 26, 37, or 38 lbs. Listed to UL 1741 for U.S.A. and Canada.
