Introduction 6 900-0020-01-00 Rev A MATE3 System Display and Controller The Radian inverter/charger has n o external controls. It can operat e 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 [...]

900-0020-01-00 R ev A 7 Commissioning Functional Test WARNING: Shock Hazard and Equipment Damage It is necessary to remove the cover of the Radian inver ter to perform these tests. The components are close together and carry hazardous voltages. Use appropria te care to avoid the risk of electric shock or equipment damage. Pre-startup Procedures 1. [...]

Commissioning 8 900-0020-01-00 R ev 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 fr om the L1 OUT terminal on one inverter to the next. When stacked in pa rallel, the wires from one inverter to the next should read 0 Vac (although individually th[...]

900-0020-01-00 R ev A 9 Operation Input Modes The Radian inverter has two sets of input co nnections 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 mo des are available, each with certain advantages which mak[...]

Operation 10 900-0020-01-00 R ev A NOTES :  The Support, Offset, and gri d-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 ble to install senstive loads under these c[...]

Operation 900-0020-01-00 R ev A 11 Grid Tied IMPORTANT: Selling power to the utility company re quires the authori zation of the local electric jurisdiction. The method used by the local utility company to accommodate this will depend on their po licies on this issue. Some may pay for power sold; others may is sue credit. Some policies may prohibit[...]

Operation 12 900-0020-01-00 R ev A  The grid-interactive functio n can only operate while the util ity grid power is stable and within specific limits.  If the AC voltage or frequency vary outside these limi ts, the inverter will stop selling. If the inverter stops selling, the MATE3 will show the reason. Sell Status messages are listed on pa[...]

Operation 900-0020-01-00 R ev 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 tran sfer circuit and will power the loads unless utility power is lost. If utility grid power is lost, then th e Radian inverter will supply energy to the loads[...]

Operation 14 900-0020-01-00 R ev A will then enter Silent (see page 22) and continue re peating this part of the charging cycle until it disconnects from the utility grid. If the reconnection was triggered by the Rebulk volt age setting, the inverter will require the charger to pass through the entire ch arge cycle, including the Absorb Voltage , A[...]

Operation 900-0020-01-00 R ev A 15 Functions The items in this section are states of operation co mmon to all Radian inverter s. These functions can be used in most or all of the input modes describe d in the preceding section. Some can be manually selected or enabled; others are automatic. All items identified as settable or adjustable have set po[...]

Operation 16 900-0020-01-00 R ev A Search An automated search circuit is available to minimi ze 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. Basi[...]

Operation 900-0020-01-00 R ev A 17 AC Current Settings The AC current settings control the amount of curren t that the inverter draws from the source(s). The amount of current is controlled by the grid or ge nerator limit settings. These settings should be adjusted to match the size of the input circuit breaker. In the MATE3 system display, if the [...]

Operation 18 900-0020-01-00 R ev A Generator A generator should be sized to provide enough powe r 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 volt age or frequency for long periods of t im[...]

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

Operation 20 900-0020-01-00 R ev 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 un dercharged or overcharged. The inverter uses a “three-stag[...]

The remaining time for the slaves will be retained in the timer for each inverter. The Absorption timer does not reset to zero when AC power is disco nnected or reconnected. It on[...]

Operation 22 900-0020-01-00 R ev A This setting is typically lower than the Float voltage setting. Although the batteries are not discharged, they are maintained at a somewhat lo wer voltage so that the maximum amount of power can be exported. It is recommend ed that this item be set at the batteries’ natu ral rest voltage. In the Grid Tied input[...]

Operation 900-0020-01-00 R ev A 23 The unit will continue cycling between Float and Sile nt 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 ac tivity as described on page 21. The unit can only enter Offset when none of the ti[...]

Operation 24 900-0020-01-00 R ev 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 below the Rebulk point, the Absorption timer will[...]

Operation 900-0020-01-00 R ev A 25 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 th em and can be hard on them over time. The Radian inverter, when equipped with[...]

Operation 26 900-0020-01-00 Rev A Multiple-Inv erter Installations (Stacking) Multiple inverters in a single syst em can support larger loads than a single inver ter can handle. Installing inverters in this conf iguration is called “stacking”. Stacking inverters d oes not refer to physically placing one on top of another. It refers to how they [...]

Operation 900-0020-01-00 R ev A 27 In parallel stacking, two or more inverters are stac ke d to create a single, common 120/240 Vac bus.  The master provides the prim ary output. The slaves ar e connected to the same output and assist the master.  The slave inverters can be programmed to activate on demand, reducing idle-power consumption . T[...]

Operation 28 900-0020-01-00 R ev A Power Save Levels Each inverter consumes approximat ely 30 watts of idle power while it remains on, even if it is not actively inverting or charging. The Power Save fu nction 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 [...]

Operation 900-0020-01-00 R ev 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 ou tput that can deliver up to 0.7 Adc to control external loads. The RELAY AUX terminals are “dry” re lay contacts with no voltage. Each [...]

Operation 30 900-0020-01-00 R ev A  Gen Alert is used as a controller fo r an AC generator with a remote start feature, although it has limited functionality. (The generator rechar g es batteries using the inverter’s ba ttery charger.) When the battery voltage falls to a low set point for a settable delay, the AUX output is acti vated. The AUX[...]

Operation 900-0020-01-00 R ev A 31  Source Status enables the AUX output whenever the inverte r acce pts an AC source. It can activate a light or alarm to show that the utility grid is present or that a generato r has started.
