Page 7: Planning
Planning Applications The Radian Series Inverter/Charger is intended for both off-grid and grid-interactive (Grid/Hybrid) applications. It is designed to use a battery bank to store energy. It can work in conjunction with photovoltaic (PV) panels to harvest solar energy, as well as wind turbines and other renewable sources. -
Page 8: Input Modes
Planning Input Modes The Radian inverter has seven modes of operation. These modes determine how the Radian interacts with an AC source. Each mode has functions and priorities that are intended for a designated application. Each of the Radian’s two AC inputs can be set to a different operating mode, so that different applications can be supported. -

Page 27: Aux Wiring
Installation AUX Wiring The Radian inverter has two sets of terminals which can respond to different criteria and control many functions. These include cooling fans, vent fans, load diversion, fault alarms, and the Advanced Generator Start (AGS) function. The 12V AUX terminals are a switched 12 Vdc power supply. They can control any of the Auxiliary Output functions available in the MATE3. -
Page 28: Generator Control
Installation In this example, the 12V AUX terminals drive a relay that diverts wind power. The relay’s coil is connected to the 12V AUX terminals. When the AUX function closes the relay (based on battery Turbine voltage), the relay diverts the excess wind power to a water heating element. -
Page 29: Figure 23 Two-Wire Generator Start (Relay Aux)
Installation In other cases, or in the case of a three-wire-start generator, the inverter should use the 12V AUX terminals instead, in conjunction with a three-to-two wire converter. (See pages 27 and 28.) RELAY AUX Terminals Two-Wire-Start Generator Starting Switch Figure 23 Two-Wire Generator Start (RELAY AUX) Two-Wire-Start (12V AUX Terminals) The 12 Vdc signal provided by the 12V AUX terminals can be switched on and off to provide a start... -
Page 30: Figure 25 Three-Wire Generator Start (Example)
Installation Three-Wire-Start A “three-wire-start” generator has two or more starting circuits. It usually has a separate switch or position for cranking the generator. A three-wire generator has fewer automated functions than a two-wire. It usually requires multiple controls for starting, running, or stopping. The inverter terminals cannot control this type of generator without using a three-wire to two-wire conversion kit. -

Page 32: Figure 27 Single-Inverter Ac Wiring With Gs Load Center
Installation NOTES: 1. Ground wiring is not shown for reasons of simplicity. Regardless, this system must be connected to a grounded, permanent wiring system. See page 19. 2. The Radian inverter has separate neutral connections for grid input, generator input, and output. These are electrically common. If an external neutral bus exists (as shown in the GSLC), not all of the Radian neutral connections need to be made. -
Page 33: Multiple-Inverter Ac Installations (Stacking)
Installation Multiple-Inverter AC Installations (Stacking) Installing multiple inverters in a single AC system supports larger loads than a single inverter can handle. This requires stacking. Stacking refers to how the inverters are wired within the system and then programmed to coordinate activity. Stacking allows all units to work together as a single system. The GS3548E and GS7048E models can stack up to ten units in parallel. - Page 34 Installation Connect all units other than the master to ports 2 and above on the communications manager. The system display may have other port restrictions pertaining to stacking. In general, it is always important to keep track of units and ports for programming purposes. Programming involves using the system display to assign a status and stacking value to the inverter on each port.
