10.3 Production Graphs
The following sections illustrate the inverter production/derating in terms of
ambient temperature, altitude and grid voltage.
10.3.1 High Temperature Derating Graph
When the ambient temperature is higher than 113℉ (45℃), the inverter
output power (Pn) will begin to derate, as shown in Figure 10-1:
