Outback Power Radian Grid Tie/ Off Grid Inverter GS4048 4000w 48v

Outback's new Radian inverter works equally well as a grid tie or off-grid inverter. There are two separate AC inputs, one for the bi-directional grid connection and one for a back-up generator. There is a built-in 50 A transfer switch at 120/240 VAC. The output is 120/240 VAC split phase in each unit for easy tie-in to US standard wiring and grid connections. The Radian features 4kW of continuous output power and can support large dynamic load variations and surge loads, making it well-suited for demanding commercial applications as well as residential use. With two power stages, it is able to provide high efficiency and redundancy for critical applications, and the modular design is field serviceable. The Radian can be parallel stacked with up to 10 inverters for 40kW total output. The Radian also has auxiliary controls which include a contact closure, a 12 VDC output signal and terminals for a remote on/off switch.

The inverter comes with a standard 5-year warranty. An optional 10-year extended warranty is available where required by state incentive programs. The Radian is for indoor use only. Dimensions are 28"H x 16"W x 8.7"D. Weight is 84 lbs. Listed to UL 1741 for U.S. and Canada.

You will also need a Mate 3, Hub 4 or 10, RTS, and an appropriate GSLC (below) to complete a Radian system.

The GS Load Center (GSLC) is a wiring and circuit protection enclosure that mounts under the Radian inverter. It is available in three versions:

The base GSLC includes positive and negative main inverter bus bars, a 500 A 50 mV shunt with negative terminal bar, the main DC positive breaker plate, ground ad neutral terminal bars, and 2 PV positive terminal bars. It can also accommodate up to 18 AC or DC panel mount breakers (10 top, 8 bottom), two main 175 A DC breakers and a FlexnetDC, which can be purchased separately. Up to two charge controls can mount on the right side (mounting brackets not included), and either the Hub4 or Hub10 can mount on the left side.

The GSLC175-120/240 has everything that the basic unit has and also includes two 175 A DC main breakers, an AC output and bypass breakers with interlock plate, an AC grid and generator input breakers (50 A two pole), and six AC terminal bars (3 black, 3 red). It can also accommodate 10 additional panel mount breakers and one additional main breaker, which can be purchased separately.

The GSLC175-PV-120/240 has everything that the other versions have and also includes 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 5 additional panel mount breakers, which can be purchased separately.

The AC bypass assembly is only for use with a single Radian inverter. For multiple inverters, use the basic 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, and each inverter requires two 175 A main DC breakers.

The GSLC is for indoor use only. 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. and Canada. More accessories for Outback can be found on the accessories page.
