The Radian Series Inverter/Charger is intended for both grid-interactive and off-grid applications. These inverters are designed to use a battery bank to store energy. They can work in conjunction with photovoltaic (PV) panels to harvest solar energy, as well as wind turbines and other renewable sources. These sources charge the battery, which in turn is used by the inverter.
The Radian inverter has six modes of operation. 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.
Generator: This mode is intended for an AC generator. It is designed to accept any AC generator regardless
of power or regulation mechanism. The Radian will charge from the generator even when the generator is
undersized or substandard.
Support: This mode is intended for systems that use the utility grid or a generator. However, size, wiring, or
other limitations may require temporary assistance to run very large loads. The Radian adds inverter and
battery power to the AC source to ensure that the loads receive the power they require.
Grid Tied: This mode is intended for grid-interactive systems. When renewable energy sources charge the
batteries above a selected “target” voltage, the Radian inverter will send the excess energy to any loads. If
the loads do not use all the excess energy, then the Radian will return that energy to the utility grid.
UPS (Uninterruptible Power Supply): This mode is intended for systems whose main focus is to maintain
power to the loads without any interruption during a transfer to, or from, the AC input. The transfer speed
in this mode has been reduced so that if the AC input power is disconnected or a scheduled disconnect
occurs the transfer speed will be less than 4 milliseconds.
Backup: This mode is intended for systems that have the utility grid available. This source will flow through
the Radian inverter to 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 until the power is back online.
Minigrid: This mode is intended for systems that have the utility grid as an input and a sizable amount of
renewable energy production. The system will run off the renewable energy production until the battery
voltage falls to a specified low level. When this occurs, the Radian inverter will connect to the utility grid,
which will power the loads. The Radian inverter will disconnect from the utility grid when the batteries are
The Radian Series Inverter/Charger cannot connect directly to photovoltaic arrays, wind turbines, or other renewable sources. The batteries are the inverter’s primary source of power. However, if these sources are used to charge the batteries, the inverter can use their energy by drawing it from the batteries.
The renewable source is always treated as a battery charger, even if all of its power is used immediately. The renewable source must have a charge controller or some way to prevent
overcharging. OutBack Power’s FLEXmax charge controllers can be used for this purpose, as can other products. The GSLC will facilitate the mechanical and electrical connections for up to two FLEXmax charge controllers.
