I am confused about the question/problem.
What is the reason or reasoning behind disabling surge protection?
More details needed.
Can you provide some line diagram of how you intend to connect everything?
For example:
Power -----> UPS backup unit ---> power inverter------> devices?
Correct my line diagram and include component makes, models, and specs.
Normally the PC is just plugged into the UPS and the UPS handles surge protection and power to the PC if there is an electrical outage.
Not sure about the power inverter requirement......
