im just a amatuer but looking for a device that i can not find.
could anyone help to create a list of parts to buy and a program to run (i have some experiense in arduino 3d printing programming)
im looking for a simple PWM device
i got a wind turbine that in storms will put out to much voltage for my controller to handle.
normally the safety feature just will diverse 100% of the power generated in to a dumpload and the controller shut off.
i want to harvest the power possible in all wind.
so im looking for a PWM devise that will sense the voltage generated and use PWM to diverse some of the energy to a dumpload but ONLY to keep the voltage at the maximum point of the controller, and the controller can still be on and harwest the power in to the battery bank
im thinking arduino with a small screen and some navigation buttons to select maximum volt allowed and also in real time display voltage in the line(s).
my wind turbine is 3 phase AC
im thinking solid state relays to control the dumpload
max voltage allowed by the controller is 250v
max voltage output from the turbine is 360 (might be more if it ceeps together in a hurricane :P)
this to read amps going to dump and calculated kwh in software
this to read the AC volt between the generator phase and ground:https://www.ebay.com/itm/Single-Phase-Voltage-Transformer-Module-AC-Output-Voltage-Sensor-fr-Arduino-T3L3/332427225523?epid=2267195850&hash=item4d6634e9b3:g:4wIAAOSw~HBZ8pUU
the power could be rectified if there is a problem to sence AC voltage, dumpload could also be DC.
but if ewrything could stay AC its better
by controller i mean wind generator controller witch i already got
