15A Efficient Solar Panel Protection

Dimensions: not specified; Weight: not specified; Rated current: 15A maximum (18A short-term), derated to 10A continuous without heatsink; Operating voltage range: DC 5–60V; Internal resistance: 8 mΩ per module (dual parallel configuration enables ultra-low forward voltage drop); Static quiescent current: 0.2mA at 12V (varies slightly with input voltage); Operating temperature range: -40°C to +85°C; Housing material: plastic; Colour: green. This module solves the longstanding inefficiency of using standard diodes for solar array blocking — where up to 2W of wasted heat at 10A directly reduces harvestable energy and introduces fire-risk hotspots. By replacing those diodes with an active, ultra-low-Rds(on) solution, it preserves precious watt-hours while removing thermal bottlenecks. Its design accommodates both series-connected solar strings and parallel battery banks, functioning identically whether mounted near panels, inside battery enclosures or integrated into custom DC-DC chargers. Commonly applied in UK listed-building solar retrofits (where ventilation is restricted), eco-home energy monitors, and mobile solar kits for festivals and pop-up events — where silent, cool-running, and plug-and-play reliability outweighs cost-per-unit considerations.
