Lot Of 4 - 3 Amp 200 Volt Blocking Diodes For Solar Panels

Free shipping to the lower US 48 states only,  excluding PR, Hawaii, Alaska You are buying a lot of (4) 200 Volt 3 Amp diodes for use with Solar Panels or Wind Turbines They are used to allow voltage from a solar panel  to only go in one direction. A one-way blocking diode prevents current from leaking from your battery back into the solar panel where it is dissipated as heat, depleting your battery. Use with wire strip. What size blocking diode do I need? Your diode needs to be somewhat larger than the current that is will be handling. For solar panels, we sell the 3 amp and 10 amp diodes for this purpose. 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 heat sink if it will be used for higher power applications (above 15 amps or so).
