I’m so happy to find this project! I’m hoping to make a windmill and, if conditions allow, a water mill that generate electricity, and I prefer to also make the electronics surrounding it.
I expect my windmill, however, to deliver more power than your MPPT-2420-RC can handle, namely peaking at about 1 kW.
My initial question is therefore: How difficult would it be to size the design up for the task? 1kW is really the best case scenario, so keeping the current spec at 20A and just increasing the battery voltage from 24 to 48 V should be good enough. I’m only interested in some fast pointers for now. I’m hoping it’s as simple as finding new components that can handle the voltage (and of course redo the layout, since they will be bigger).
If things go as planned, I’d be happy to contribute with my design for the benenit of Libresolar. Which I guess brings the question whether there will be a “Librewind”?
Thanks in advance!
