4.4.2 Thermal
All components on inverter board should follow below rules:
• Component using conditions (component stress) must be within component
specification including voltage rating, current rating, temperature etc.
• Component temperature should follow below:
Δ T < 30°C, at 25, 35°C.
Component temperature should be less than 70°C inside system at 35°C.
