1.I have a Upstation s backup and want to run the whole house with it. Its a 12kva unit but is set to 8kva this part got me lost. Its a online ups and need s input voltage to get it going. I need to find a way to jumpstart it from the ac-dc converter so I can turn it on without applied power.

2. Need to change the rating from 8kva to 12kva So I can utilize the 10kw power. So if anyone has any Idea on how point me in the right direction that would be great. Thanks in advance
