Temperature Derating
All Radian inverters can deliver their full rated wattage at temperatures up to 25°C (77°F). The
maximum wattage is rated less in higher temperatures. Above 25°C, the GS8048A is derated
by a factor of 80 VA for every increase of 1°C. The GS4048A is derated by 40 VA per 1°C.
Figure 11 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 Radian inverter is not
rated for operation above that temperature.
