Cost Effective, High-current Rated Diode Assembly
This high current rated, isolating diode assembly works well with higher output solar panels. It will however, begin to over heat (when the load draws more than 10 or 20 amperes) if it is not properly heat sunk. I used an old aluminum power supply heat sink (along with some heat sink thermal compound) to significantly improve the diode's operating temperature range and thereby, its operating current carrying capacity. (See the attached photo). Mounting it to a simple aluminum or steel plate should also work well as a heat sink. I would suggest using some type of heat transfer compound (such as Wakefield Thermal Compound - Part Number 120-2) to improve the heat transfer characteristics.

Pushed up to 15volts, and the drop was only .9 volts after a fuse. That was before my system regulated the power to the necessary 12 volt standard. Handles all my system can safely push—up to 330amps and will still be in 80% heat safety zone—In fact my 200 amp fuse will blow at 320amps; and since I usually run at 125amps, I am super protected. No concern the capacitor will push/surge back the wrong way now.
