Looks solid, add a heat sink if your putting out high current, perfect for me

This is a really large diode, which lets DC voltage flow in only one direction. You don't strictly need one in a solar panel system, but they are helpful to prevent any backfeed and to add another measure of safety. It should prevent any battery discharge at night when the battery has a higher potential than the solar panel, although a lot of charge controllers perform that function as well.This isn't exactly a budget item, but I was willing to order it to follow best practices in building my little solar panel system. It's good quality and comes ready to bolt to a heat sink. The included terminals are strong and up to the task, and I liked that you can drive them really snug with a nut driver instead of only with a phillips screwdriver. The diode is doing its job, and I'm satisifed with it.

Does it's job, was a bit confusing at first but now I'm using them to separate charge. I'm a newbie to solar

I installed this 50amp rated diode in my solar system which has a maximum amperage of about 30. It does stop back-flow of current. However, it gets very hot at far below the rated amperage. With 22 amps flowing, I measured 170 degrees F, which is much too hot to touch. Too hot to touch at anything over 10 amps. I would not want to test what 50 amps would do. I have ordered a 250 amp version and hope that will solve the over-heating issue.

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.

I have a complicated circuit on the RV with a thorny problem that I wasn't sure how to fix. I believe this is just what the doctor ordered!

Worked great for my 66 El Camino

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.

4 stars because its a little bit on the expensive side, but otherwise works well and I like the way it mounts. Using to prevent back feed of capacitors from 700w 12v inverter to my noco onboard charger causing voltage spikes that would set off high voltage alarm on the charger, would buy again.
