I am repairing a xantrex st2500. I only have about 150 watts of solar power and was thinking about supplementing with wind power. My idea is if I hook up the wind mill to some batteries in series (say 48v) and the grid tie to the battery bank it should be ok. I am fixing it now, it was bought broke and I don't want to have to fix it again. I know I cant just put the windmill right to it.
The voltage for the grid tie inverter is 42v - 75v and it takes up to 2500w.
I was aslo wondering about this nominal DC input range. Does that mean each power source must be atleast 42V or does the total of each need to be 42V or greater? Do they all need to be the same voltage or amperage?
I have the user manual but it is unclear to me. If anyone thinks they can help and want to read it, I can email it.
