Applications
The International Series GFX inverters are intended for both off-grid and grid-interactive applications.
These models 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.
In grid-interactive applications, the grid is the primary source of power to run the loads. When excess
PV (or another renewable energy source) is available from the batteries, the inverter supports those
loads with the PV. When the PV exceeds the load requirements, the inverter sells that excess power
back through its input, to the utility grid. When the utility grid is not available, the inverter takes over
to run the loads with PV and energy stored in the battery bank.
If the inverter is used as the primary source, the grid power will be used when the batteries have been
drained. In this situation, the AC power, PV harvest, or other renewable energy can be used to
recharge the battery bank.
In off-grid applications, the inverter can use the harvested energy from the battery bank as the
primary power source. An AC generator can also be connected to support the system when required.
Figure 3 Applications (Example)
*Excess AC power not being used by the AC loads. Uses bidirectional AC input for sell-back. Requires a GFX Inverter/Charger
programmed for a grid-interactive application.
**AC power used for input only. GFX inverter should have its grid-interactive feature disabled when using a generator.
