900-0020-01-00 Rev A 5 Introduction Welcome to OutBack Power Technologies Thank you for purchasing the OutBack Radian Series Inverter/Charger. This product offers a complete power conversion system between batteries and AC power. It can provide backup power, sell power back to the utility grid or pr...

Introduction 6 900-0020-01-00 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 i...

900-0020-01-00 Rev A 7 Commissioning Functional Test WARNING: Shock Hazard and Equipment Damage It is necessary to remove the cover of the Radian inverter to perform these tests. The components are close together and carry hazardous voltages. Use appropriate care to avoid the risk of electric shock ...

Commissioning 8 900-0020-01-00 Rev A After programming (if any) is completed, perform the following steps: 1. If other inverters are on the system, use a DVM to verify correct voltage from the L1 OUT terminal on one inverter to the next. When stacked in parallel, the wires from one inverter to the n...

900-0020-01-00 Rev A 9 Operation Input Modes The Radian inverter has two sets of input connections for multiple AC sources. (See the Radian Series Inverter/Charger Installation Manual for more information.) With the MATE3, each input can be programmed to a particular operating mode. Six modes are av...

Operation 10 900-0020-01-00 Rev A NOTES :  The Support, Offset, and grid-interactive functions of the Radian are unavailable in this mode.  Any AC fluctuations that are accepted by the inverter will be transferred to the output. The loads will be exposed to these fluctuations. It may not be advisa...

Operation 900-0020-01-00 Rev A 11 Grid Tied IMPORTANT: Selling power to the utility company requires the authorization of the local electric jurisdiction. The method used by the local utility company to accommodate this will depend on their policies on this issue. Some may pay for power sold; others...

Operation 900-0020-01-00 Rev A 13 Backup This mode is intended for systems that have utility grid available as the primary AC source. This source will pass through the Radian inverter’s transfer circuit and will power the loads unless utility power is lost. If utility grid power is lost, then the Ra...

Operation 900-0020-01-00 Rev A 15 Functions The items in this section are states of operation common to all Radian inverters. These functions can be used in most or all of the input modes described in the preceding section. Some can be manually selected or enabled; others are automatic. All items id...

Operation 16 900-0020-01-00 Rev A Search An automated search circuit is available to minimize the power draw when no loads are present. When enabled, the inverter does not always deliver full output. The output is reduced to brief pulses with a delay between them. These pulses are sent down the outp...

Operation 900-0020-01-00 Rev A 17 AC Current Settings The AC current settings control the amount of current that the inverter draws from the source(s). The amount of current is controlled by the grid or generator limit settings. These settings should be adjusted to match the size of the input circui...

Operation 18 900-0020-01-00 Rev A Generator A generator should be sized to provide enough power for all inverters, both for loads and for battery charging. It is usually recommended that the generator be sized at twice the wattage of the inverter system. Many generators may not be able to maintain A...

Operation 900-0020-01-00 Rev A 19 Offset This function is designed to use excess battery energy to power the loads, even when an AC source is present. This allows the system to take advantage of renewable energy sources, in effect “offsetting” dependence on the AC source. When a renewable source of ...

Operation 20 900-0020-01-00 Rev A Battery Charging IMPORTANT: Battery charger settings need to be correct for a given battery type. Always follow battery manufacturer recommendations. Making incorrect settings, or leaving them at factory default settings, may cause the batteries to be undercharged o...

The remaining time for the slaves will be retained in the timer for each inverter. The Absorption timer does not reset to zero whe...

Operation 22 900-0020-01-00 Rev A This setting is typically lower than the Float voltage setting. Although the batteries are not discharged, they are maintained at a somewhat lower voltage so that the maximum amount of power can be exported. It is recommended that this item be set at the batteries’ ...

Operation 900-0020-01-00 Rev A 23 The unit will continue cycling between Float and Silent for as long as the AC source is present. However, if excess DC power is available and the battery voltage rises above the Sell Voltage set point, the unit can resume Offset activity as described on page 21. The...

Operation 24 900-0020-01-00 Rev A The Absorption timer continues this behavior even if the charger is still on. For example, if the charger is in Float stage and there is a significant battery drain, the charger may not be able to maintain the batteries at the Float voltage. Once the batteries fall ...

Operation 26 900-0020-01-00 Rev A Multiple-Inverter Installations (Stacking) Multiple inverters in a single system can support larger loads than a single inverter can handle. Installing inverters in this configuration is called “stacking”. Stacking inverters does not refer to physically placing one ...

Operation 28 900-0020-01-00 Rev A Power Save Levels Each inverter consumes approximately 30 watts of idle power while it remains on, even if it is not actively inverting or charging. The Power Save function allows the option to put some or all slave inverters into a quiescent state known as Silent m...

Operation 900-0020-01-00 Rev A 29 Auxiliary Terminals The Radian inverter has two sets of terminals which can respond to different criteria and control many functions. The 12V AUX terminals provide a 12 Vdc output that can deliver up to 0.7 Adc to control external loads. The RELAY AUX terminals are ...

Operation 32 900-0020-01-00 Rev A System Display-Based Functions Advanced Generator Start (AGS) As noted under the Gen Alert feature (see page 31), the system is capable of starting a generator. Gen Alert simply starts and stops the generator based on battery voltage. For more advanced control, the ...
