Radian™Series

GS7048E & GS3548E Inverter/Chargers

OutBack Power’s acclaimed Radian Series made the benets of

Grid/Hybrid technology available and accessible in one agile

powerful, platform ideal for nearly all o-grid or grid-connected

system architectures.

The Radian Series GS7048E and all-new GS3548E features dual AC

inputs for grid/generator exibility with no external switching required,

unparalleled surge capability and operational stability, easy eld

upgradeability and stacking capability for large system scaling, simplied

system commissioning through a powerful, easy-to-use conguration

wizard, and multi-mode operational exibility.

In addition, both models have new Advanced Battery Charging (ABC)

prole options to support leading-edge battery technologies such

as Lithium-Ion and others, and enhanced diagnostics for improved

performance. And both incorporate OutBack’s GridZero technology, a

superior level of intelligence in 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. GridZero operation

makes it possible for a smaller inverter and battery system to perform

like a much larger one when required, putting stored and renewable

energy sources to work and minimizing grid dependence.

As truly global products, the Radian Series GS7048E and GS3548E

inverter/chargers oer selectable voltage and frequency for use in

a wide variety of locations, and innovative grid interface protection,

which allows precision programming and control to accommodate

shifting utility requirements in areas with high PV penetration or specic

interconnection requirements. Complete system interfacing using the

OutBack MATE3 and HUB communications manager enables the Radian

Series to be connected with other OutBack Power electronics providing

industry leading integration and a scalable power solution. Up to 10

units can be connected in parallel for systems up to 70kW continuous

power output.

The GS7048E and GS3548E are IEC certied to meet the most stringent

worldwide PV safety and emission standards.

This product is for Europe, Asia and other global markets.

Welcome to OutBack Power Technologies

Thank you for purchasing the OutBack Radian Series Inverter/Charger. Designed for FLEXgrid™

operation, it offers a complete power conversion system between batteries and AC power. As part of

an OutBack Grid/Hybrid™ system, it provides grid-interactive service, selling excess renewable energy

back to the utility. It can also provide backup power or complete off-grid service if necessary.

7000 watts (7 kW) continuous power at 48 Vdc

16.3 kVA peak surge capacity

Stackable in parallel configuration up to ten inverters

Stackable in three-phase configuration with three inverters

Modular internal design allows low idle consumption and high efficiency at both high and low

power operation

Field-upgradeable firmware

Certified by ETL to IEC 62477-1

Uses the MATE3 System Display and Controller (sold separately) for user interface as part of a

Grid/Hybrid system

IMPORTANT:

The Radian Series Inverter/Charger is not intended for use with the OutBack MATE or

MATE2 System Display and Controller. It is only compatible with the MATE3 System

Display and Controller.

NOTE: This product has a settable AC output range. In this book, many references to the output refer

to the entire range. However, some references are made to 230 Vac or 50 Hz output. These are

intended as examples only.

Introduction

6 900-0145-01-00 Rev A

MATE3 System Display and Controller

The Radian inverter/charger has no external controls. It can operate normally without an external

control or interface. Basic modes and settings are pre-programmed at the factory. (See page 47 for

default settings.) The Radian inverter has no display or LED indicators. It is not possible to monitor its

status or operating mode without a metering device.

The MATE3 System Display and Controller (sold separately) is an OutBack product designed to

accommodate programming and monitoring of a Grid/Hybrid power system. The MATE3 provides the

means to adjust the factory default settings to correctly match the installation where needed. It

provides the means to monitor system performance and troubleshoot fault or shutdown conditions.

It also has data logging and interface functions using the Internet.

Once settings are modified using a MATE3, the MATE3 can be removed from the installation. The

settings are stored in the nonvolatile memory of the Radian. However, it is highly recommended to

include a MATE3 as part of the system. This provides the means to monitor system performance and

respond quickly should it be necessary to correct a fault or shutdown condition.

The MATE3’s Configuration Wizard is capable of automatically configuring inverters to a series of

preset values. This is often more efficient than attempting to manually program each setting in each

inverter. Affected fields include system type, battery charging, and AC source configuration. (For

more information, see the MATE3 Owner’s Manual).

NOTE: The Radian Series Inverter/Charger can only be used with MATE3 firmware revision

002.010.xxx or higher.

IMPORTANT:

Some functions are not based in the inverter, but are part of the MATE3

system display’s firmware. They will not function if the system display is

removed. These functions are listed beginning on page 32. For a detailed

description of functions and programming, please see the MATE3 Owner’s

Manual.
