Features:
-Energy Harvest: It features conversion efficiency of up to 94 percent, higher than 75 percent of PWM solar controllers, and will intelligently achieve full charge.
-Innovative MPPT Tech: The maximum power point of multi wave peak will always be rapidly and automatically captured.
-Multi-Stage Charging: A multi-stage algorithm is designed to enhance battery performance and increase its lifespan.
-Upgraded Protection: PV/ battery reverse polarity, over-charge/ discharge, over load/temperature, back feeding night and short circuit protection are embedded.
-Durable Construction: Sturdy ABS housing is impact and shock resistant, and the cover protects terminals against corrosion and shorting.
-Rapid Heat Dissipation: With MOSFET to allow larger currents, the upgraded aluminum heat sinks are designed to rapidly dissipate heat for smoother operation.
-Highly Compatible: This solar MPPT controller fits a variety of lead acid deep cycle batteries, including flooded, AGM and GEL, and LiFePO4 batteries.
-User Friendly Design: This MPPT controller features indicators for real-time status of solar panel, load & battery, and USB output for charging mobile devices.
