Allaluminum housing with an aluminum heat sink provides heat dissipation, ensuring reliable and efficient operation in a variety of environments. LCD display shows input voltage, output voltage, output current, and temperature clearly at a glance. MPPT technology achieves up to 99% tracking efficiency, delivering 1520% higher efficiency than PWM algorithms. Protection mechanisms include under voltage, over temperature, short circuit, output over current, over load, and backflow prevention, delivering robust safety for continuous use. Function and performance: MPPT solar charging controller with clear status display and comprehensive protections for reliable power management. Compatibility: suitable for integration into solar charging setups with standard panels and battery systems. Size and material: compact form factor with durable allaluminum housing designed for portable or fixed installations. Use scenarios: Offgrid solar systems for RVs, boats, cabins, or remote locations where reliable charging and easy monitoring are needed. Home backup or emergency power setups requiring continuous voltage and current visibility and strong protection features. Fieldwork or outdoor applications where a compact, durable MPPT controller supports portable solar generators and mobile power kits.
