The folllowing images depict a charge controler that came witjh one of my wind turbins ( a 450 W Chinese PMA). The Packge was called a "Hybrid" wind and solar, actualy the controller had inputs for both a 3 phase turbine and solar. I used it for about 6 months, never really trusting it. So while cleaning the shed this weekend, decided to take it apart
You will notice that the unit as a dump load on the right, it also has the ability to measure input voltage before cut-in...(hmmm think about that for a sec, needs to be rectified then read voltage, then have another diode befor the battery
This a shot with the case removed, notice the dump load (7 ft of 2 strand (nichrome ribon?, 1 ohm ), there is alos quite a bit of oxidation dust under the ribbon.
This badly drawn (ms paint) shows the wire tracing for the 5 bridge rectifiers. Notice that the dump load is activated by the microcontroller, but does not dump from the battery,dumps directly from source after the first set of rectifiers. The microcontroller uses an Atmel ATMEGA48V-AU (8 bit, 8 channel 10 bit ADC) as the brain, there is also a 7805 regulator the board. (most of the controller parts are smd's and not salvagable)
Ok things for salvage.
1. 32x4 LCD display, with a serial 3 wire driver...should be able to use that (10$ maybe)
2. 4 N Mosfets IRF3205 (Vdss 55V. ID 110A) ... might find a use (4 $ total)
3. 1 TIP2250 Darlingtom trans. (.50$)
4. Nice big heatsink (10$ maybe)
5. 5 KBPC3510W Bridge rectifiers (35A/1000V) (maybe 12$ total) .. could find a use
6. Dumpload No idea on that one.. but I'll keep it around
