Product Specifications

• Modular, stackable: up to nine units can be combined

for three-phase operation and ten in parallel, single-

phase operation

• Compliant with California Rule 21 and Hawaii 14H

grid support requirements

• Seven different programmable operating modes,

with generator assist

• GridZero operating mode minimizes grid dependence

in areas where incentives are changing and utility sell-

back is limited

• 8000 and 4000VA of continuous power with dual AC

inputs and peak operating efﬁciency of 96%

• Off-grid and grid-tied functionality in one unit

• Integrates both grid and generator with dual inputs

• Performs AC coupling with both legacy and UL1741SA

inverters, using frequency shifting

OutBack Power’s acclaimed Radian Series

made the beneﬁts of solar technology

available and accessible in one platform.

The Radian GS8048A and GS4048A features dual AC inputs

for grid/generator ﬂexibility with no external switching required,

unparalleled surge capability and operational stability, easy ﬁeld

upgrade-ability and stacking capability for large system scaling,

simpliﬁed system commissioning through a powerful, easy to use

conﬁguration wizard and multi-mode operational ﬂexibility.

The Radian GS8048A and GS4048A incorporate OutBack’s

GridZero technology: energy management for self-generation and

self-consumption programs providing precise balancing between

using stored energy, solar and utility power, blending-in the latter to

overcome surges and load spikes when needed.
