Applications
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.
Figure 3 Applications (Example)
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.
NOTE: See the Radian Series Inverter/Charger Operator’s Manual for additional information on these
modes, including the benefits of using each mode.
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.
