Thermal
All components on inverter board should follow below rules:
1. Component using conditions (component stress) must be within component specification including voltage
rating, current rating, temperature etc.
2. Component temperature shold follow below:
T <=30 Celsius degrees, at 25, 35 Celsius degrees.
Component temperature should be less than 70 Celsius degrees inside system at 35 Celsius degrees.

The maximum inrush current will be less than 50A and 100A when the adapter
is connected to 115Vac(60Hz) and 230Vac(50Hz) respectively.
It should provide an efficiency of 84% minimum, when measured at maximum
load under 115V(60Hz).
