AntiReflux Solar diode Module This solar diode module prevents battery discharge back into solar panels when panels are not producing power. It improves charging efficiency by ensuring current flows into the battery and not back into the array, reducing power loss during low or no sunlight periods. Key benefits Prevents reverse current that discharges batteries at night or during shading, protecting stored energy. Improves overall charging efficiency by maintaining correct current direction, which helps maximize usable power from the solar array. Simple inline protection that complements charge controllers and battery systems without major changes to existing setups. Compact and durable design for reliable longterm operation in solar installations. Primary functions Oneway current flow control to stop battery backfeed into solar panels. Low voltage drop to minimize energy loss during charging. Thermaltolerant diode assembly for stable performance under normal solar system temperatures. Compatibility Works with photovoltaic panels, charge controllers, and battery banks commonly used in offgrid and gridtied systems. Suitable for leadacid and lithium battery systems when used as part of a proper solar charging setup. Compatible with small to midsize solar arrays for residential, mobile, and light commercial applications. Size and material Compact module designed for inline mounting to minimize space requirements. Robust housing with sealed diode assembly for protection against dust and typical outdoor conditions. Standard electrical terminals for straightforward connection to existing wiring. Performance Designed to offer low forward voltage drop to keep conversion losses minimal. Reliable current handling appropriate for typical solar charging currents. Stable operation that helps maintain battery charge levels by preventing unwanted discharge. Practical use scenarios Offgrid cabin: Install the diode module between the solar panel array and battery bank to prevent overnight battery drain and improve daily charge retention. Recreational vehicle or boat: Use the module to protect onboard batteries when solar panels are not generating, reducing the need for frequent manual recharging. Solar lighting and small installations: Add the diode module to street lights or remote sensors powered by solar panels to preserve battery life during periods of low sunlight. Installation and maintenance Install inline on the positive lead between the solar panel output and the battery or charge controller input. Minimal maintenance required. Periodic visual inspection of connections and housing recommended to ensure continued performance. This antireflux solar diode module provides a straightforward and reliable way to prevent reverse current flow, improve charging effectiveness, and protect battery systems in a variety of solar applications.
