Temperature Derating
All FXR inverters can deliver their full rated wattage at temperatures up to 25°C (77°F). The FXR
maximum wattage is rated less in higher temperatures. Above 25°C, each inverter model is derated by
a factor of 1% of that model's rated wattage for every increase of 1°C. This derating applies to all
power conversion functions (inverting, charging, selling, offsetting, etc.)
Figure 21 is a graph of wattage over temperature, showing the decrease in rated wattage with
increased temperature. The graph ends at 50°C (122°F) because the FXR inverter is not rated for
operation above that temperature.
