Applications
The International Series GFX inverters are intended for on-grid, 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 on-grid applications, grid power is used 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.
