40 Amp 600 Volt Blocking Diode
These are a must for solar panels or wind turbines that do not have diodes like DIY solar panels, DC wind turbines, or hydroelectric generators.
A blocking diode is used to restrict electrical flow in one direction, similar to a back-flow prevention device.
Please note that
it is necessary to mount this diode in an aluminum heat sink to keep it cool
, otherwise it will burn out. We do not include the heat sink, however, you may easily make your own using any thin aluminum.
What size diode do I need?
Your diode needs to be somewhat larger than the current that is will be handling. If your solar panel will not exceed 2 1/2 of amps of current, then the 3 amp version is fine. The 10 amp diode is acceptable for panels up to about 9 1/2 amps. Solar panels with more charge current then this would require a larger diode (see our 75 amp diode). This larger diode can be placed in-line with the common positive wire coming from your solar panels to your charge controller to handle multiple panels at one time. Please note: A larger diode may require a heatsink if it will be used for higher power applications (above 15 amps or so.)
Do I need a diode for my wind turbine?
You will only need a blocking diode if your motor has brushes (some electric motors like the Ametek have brushes).  The Missouri Wind and Solar Freedom™ and Freedom II™ PMG, Super Dual PMA, and Victory PMA are brushless and do not require a diode.
If the turbine has brushes then yes, you need a diode.
If it is DC motor, then yes you need a diode.
If it is single phase AC you need a single phase bridge rectifier.
If it is 3 phase AC then you need a 3 phase bridge rectifier (like a car alternator), if it is not already included.
Check with your turbine supplier for more info.
Do I need a diode for use with my solar panel?
Solar panels require a diode to prevent current flow back into the battery when there is little or no light. For solar panels, a 3 amp or 8 amp diode can be used for this purpose. You might also want to install a bypass diode to prevent a shaded panel from drawing down other panels. These same diodes can be used. Place diodes in a ABS project box. If you are using a solid state charge controller, you may not need a blocking diode.
Below is an example of how it’s installed.
