As they're A/C they will always be out of sync phase wise, you cant connect them in series or parallel
I haves asked for solutions so the smartest around can give their solution about how to do this.
Each wind turbine will have its own controller that will provide 50V DC and I am searching for solutions how to connect output from wind controller. In series or parallel, series of DC with isolated DC-DC boost is very good because it can be feed into 120V - 450V input from solar MPPT inverter that will charge batteries and provide WIFI monitoring over the year.
So what is your solution ?
