  • Taking a look inside the HF-94519 Solar Fan Controller and fixing some issues.

    This was a kit HF sold back in the early to mid-2000s and it consisted of a pair of 15W amorphous solar panels on a steel frame, a ~7″, 12V fan rated at 251CFM air flow and a small solar charge controller / fan controller. Optionally, you could add a lead acid battery onto the unit to allow the cooling fan to run if the panel output dropped too low.

    Some good information on the 4069 CMOS hex inverter:

    https://www.talkingelectronics.com/ChipDataEbook-1d/html/4069.html

    I suspect they are using the “gated oscillator” circuit to turn the “PWM” function on and off, likely via the small switching transistor. I didn’t want to try and remove the PCB as that would require de-soldering lots of wires.

    I think the supplied fan drew more current than the panels and PWM charge controller could put out and thus they had to limit the speed and current of the fan output. If they didn’t do this, the fan would discharge the battery even if the panels were in full sun!

    The 75N06 N-channel MOSFET was used to limit current to the fan by providing about a 4.5V drop. This dropped the current requirements of the fan enough that let the panels and charge controller keep current flowing into the battery.

    This, however, created a new issue. The ~5W of heat from the MOSFET that sat just below the thermostat switch was enough to keep the thermostat turned on even if the outside temperature had fallen below the set point.

    I modified the controller by bypassing the MOSFET circuit and ran the battery negative to the fan negative via the 3A fuse and the thermostat. This effectively eliminates that part of the circuit and with the ~250mA fan I plan to use, there’s no problem for the charge controller to run the fan and charge the battery at the same time.

    I used to use this controller to partially heat my house some years ago:

    aki esta mi cajon de sonido de 500watts para la cg 125cc DXR las bosinas son de
    la misma marca que el ampli, pero el detalle es que las bosinas
    son de 420watts y el ampli de 500, por lo que se distorsiona la
    musica un poco al subirle a todo. el ampli se alimenta a 12v se
    los conecto a la moto.
    salio barato ya que el cajon ya lo tenia pero le quite la bosina
    las bosinas salieron con todo y cabe, tornillos, mica y etc. $210
    el ampli DXR AMP-220 500watts : $250
    Ahora le inserte dos twiter en la parte del medio de las bosinas y se escucha mas claro.
