Page 7: Introduction
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 provide complete stand-alone off-grid service. -
Page 8: Mate3 System Display And Controller
Introduction 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. -
Page 9: Commissioning
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 or equipment damage. -
Page 10: Powering Down
Commissioning 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 next should read 0 Vac (although individually they should still read 120 Vac with respect to neutral). -
Page 11: Operation
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 available, each with certain advantages which make it ideal for a particular application. -
Page 12: Support
Operation 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 advisable to install senstive loads under these conditions. ... -
Page 13: Grid Tied
Operation 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;... -
Page 14: Ups (Uninterruptible Power Supply)
Operation The grid-interactive function can only operate while the utility grid power is stable and within specific limits. If the AC voltage or frequency vary outside these limits, the inverter will stop selling. If the inverter stops selling, the MATE3 will show the reason. Sell Status messages are listed on page 43. ... -
Page 15: Backup
Operation 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 Radian inverter will supply energy to the loads from the battery bank. - Page 16 Operation will then enter Silent (see page 22) and continue repeating this part of the charging cycle until it disconnects from the utility grid. If the reconnection was triggered by the Rebulk voltage setting, the inverter will require the charger to pass through the entire charge cycle, including the Absorb Voltage, Absorb Time, Float Voltage, and Float Time settings (as well as Offset).
-
Page 17: Functions
39 of this manual. (If the voltage drops below this point, the inverter automatically recovers.) For the standard GS8048 inverter, the high battery cut-out voltage is 68 volts. It cannot be changed. This function is intended to protect the inverter’s output and loads. Continuing to invert on a high DC voltage may produce a distorted waveform. -
Page 18: Search
Operation 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 output lines to see if a resistance is present. - Page 19 Operation 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 circuit breaker. In the MATE3 system display, if the Inverter Input Priority or AC Input and Current Limit menus are set to Grid, the inverter uses the grid settings.
-
Page 20: Generator
Operation 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 AC voltage or frequency for long periods of time if they are loaded more than 80% of rated capacity. -
Page 21: Offset
Operation 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 energy raises the batteries above a designated reference point (or “target”), the inverter exports power to the loads in order to bring the voltage back down or to prevent it from rising further. -
Page 22: Battery Charging
Operation 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 or overcharged. The inverter uses a “three-stage”... -

Page 24: Float Stage
Operation 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’ natural rest voltage. In the Grid Tied input mode, excess power is sent first to any loads on the inverter’s output, using the Offset function (see page 19). -
Page 25: Figure 5 Repeated Charging Cycles
Operation 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 unit can only enter Offset when none of the timers are active. -
Page 26: Equalization
Operation 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 below the Rebulk point, the Absorption timer will begin accumulating time. - Page 27 Operation Conversely, when batteries are warmer than room temperature, the electrolyte reaction is somewhat hyper-reactive. It takes less energy than usual to charge them. Delivering the full (room-temperature) amount of energy would overcharge them and can be hard on them over time. The Radian inverter, when equipped with the Remote Temperature Sensor (RTS) will compensate for changes in temperature.
-
Page 28: Multiple-Inverter Installations (Stacking)
Operation 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 on top of another. It refers to how they are wired within the system and then programmed to coordinate activity. -
Page 29: Figure 7 Example Of Parallel Stacking Arrangement (Three Inverters)
Operation In parallel stacking, two or more inverters are stacked to create a single, common 120/240 Vac bus. The master provides the primary output. The slaves are connected to the same output and assist the master. The slave inverters can be programmed to activate on demand, reducing idle-power consumption. They will remain off until the loads exceed a certain threshold. -
Page 30: Power Save Levels
Operation 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 mode. This mode minimizes the inverter’s idle consumption. -
Page 31: Auxiliary Terminals
Operation 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 “dry” relay contacts with no voltage. Each set of terminals has its own set of programmed criteria. - Page 32 Operation Gen Alert is used as a controller for an AC generator with a remote start feature, although it has limited functionality. (The generator recharges batteries using the inverter’s battery charger.) When the battery voltage falls to a low set point for a settable delay, the AUX output is activated. The AUX output is used to energize a relay.
- Page 33 Operation Source Status enables the AUX output whenever the inverter accepts an AC source. It can activate a light or alarm to show that the utility grid is present or that a generator has started. Alternately, it could be used to show that the source has disconnected.
-
Page 34: System Display-Based Functions
Operation 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 inverter system can use the Advanced Generator Start (AGS) feature, which runs through the entire three-stage charging cycle. -
