amiciSmart 400W MPPT Solar Charge Controller with Step-Down Module, Weatherproof MPPT Solar Charge Controller

High Efficiency: Achieve up to 97% efficiency with this 400W MPPT solar charge controller, optimizing your solar power usage. Dual Functionality: Acts as both an MPPT controller and a step-down (buck) converter, offering versatile power management. Input voltage ranges from 18V to 55V, with adjustable output voltage from 10V to 30V to suit various needs. Weatherproof Design: Engineered to endure harsh weather conditions, providing reliable performance in any environment. Overheating Protection: Automatically reduces output power when the temperature exceeds 100°C and shuts off at 110°C, resuming normal operation once it cools down to 85°C. Advanced Protection Features: Includes overcharge, undervoltage, over-discharge, and short-circuit protection, ensuring the safety and longevity of your solar power system. Note: The controller will shut down if the input voltage falls below 15V and will resume operation when the input voltage returns to normal.
