328V 15A Current Ideal Diode for Solar Reverse Irrigation and Battery Charging Backflow Protection Keep power flowing where you want it and stop it where you don't. This current ideal diode provides reliable, lowloss reverse current protection for 3–28V systems up to 15A, making it an effective and simple solution for solar arrays, battery charging circuits, and irrigation controller backflow prevention. Key benefits Prevents backflow safely and efficiently: Acts as a solidstate oneway valve for current, protecting batteries and power sources from reverse discharge without the heat and voltage loss of a traditional diode. Low voltage drop and higher efficiency: Designed to minimize forward voltage drop and reduce wasted power, improving overall system efficiency compared with conventional diodes. Reliable and maintenance: No moving parts or mechanical relays; provides long service life in continuous or intermittent duty applications. Fast response and stable protection: Reacts instantly to reversepolarity conditions and prevents damaging backflow in charging and power distribution systems. What it does (functionality) Provides idealdiode behavior for DC systems between 3V and 28V. Carries continuous current up to 15A while preventing reverse current flow. Integrates seamlessly into power lines to protect batteries, solar panels, and connected loads from undesired discharge paths. Key attributes Voltage range: 3–28V DC, suitable for typical lowvoltage solar and battery systems. Current rating: 15A continuous, for current branch protection and smalltomedium power systems. Technology: Solidstate idealdiode implementation for low forward drop and fast protection. Compatibility: Designed for 12V and 24V systems and compatible with solar panels, charge controllers, battery banks, DC pumps, and irrigation controllers. Form and installation: Compact module for inline use or easy PCB integration; suitable for retrofits and installations. (Consult the product's mounting and wiring instructions for recommended connection methods.) Performance: Low conduction loss and stable operation under normal operating conditions; reduces heat generation compared with standard silicon diodes. Use cases / applications Solar charge protection: Place between a solar panel array and a battery bank or charge controller to prevent battery discharge into the panels at night or during shading, preserving battery charge and preventing reverse current damage. Irrigation and remote pumps: Protect a 12V or 24V irrigation controller or pump power line from backfeed when multiple power sources or control circuits are present, ensuring valves and controls remain in the intended state. Battery charging systems: Install in battery charging circuits to block discharge through chargers or auxiliary circuits when the charging source is disconnected or reversed, increasing system safety and reliability. Why customers choose this product Simple, effective protection without the heat and inefficiency of regular diodes. Broad voltage compatibility and a 15A rating fit common solar and battery setups. Solidstate design reduces maintenance and improves system uptime. Easy to integrate into existing installations for immediate protection. Installation and safety notes Verify system voltage is within 3–28V before installation. Ensure wiring and connectors are rated for the expected current and environmental conditions. Follow proper polarity when wiring; incorrect connection can prevent protection and may damage components. For applications near the 15A limit, provide appropriate cooling, wire sizing, and fuse protection as required by your system design. This ideal diode module is a practical, reliable choice to protect lowvoltage power systems from reverse current and backflow, delivering higher efficiency and safer operation for solar, battery charging, and irrigation applications.
