Applications
OutBack inverter/chargers are designed to use a battery bank to store energy. They work together
with power from the utility grid or from renewable energy sources, such as photovoltaic (PV)
modules, wind turbines, and other renewable sources. These sources charge the battery, which is
used by the inverter.
The FXR inverter’s settings can be changed to accommodate many applications.
These include off-grid, backup, and grid-interactive applications.
The FXR inverter has one set of terminals for a single AC source. However, it can use two different
AC sources when an external transfer switch is installed. The inverter can be independently
programmed for each source. It is common to use utility grid power and a gas or diesel generator.
Other combinations of AC sources are possible.
This product includes grid support functionality according to UL1741 SA. See the
Operator’s
Manual
for more information. Contact the utility company for any specific installation requirements.
Figure 3 Applications (Example)
In Figure 3, the inverter uses a bidirectional AC input to sell power back to the utility grid. The
power being delivered to the grid (labeled “AC Out”) is excess AC power not being used by the AC
loads. Selling requires an inverter/charger with
