Thanks for reading my question.
I am trying to test a grid tie inverter that needs a minimum of 200 vdc 600 vdc max to operate.
The source can not be the grid as far as I know. So I need to mimic a PV array.
Cost is an issue - this is only a sync test - so I was wondering if I could use an older ballast that puts out 339 v ac (after the ups 120v) - bridge rectifier...and get my minimum dc voltage. I can't find a step up transformer locally....
If you see other possibilities...Im all ears. The UPS batteries in Europe produce the minimum and I have seen them rectify to get them to run the test..our ups are commonly 120 ac...not enough. to rectify.
Thanks for the guidance.
