If you’ve been searching for a solar controller that reigns supremacy in energy conversion, this solar MPPT controller by ATEM POWER must be the top candidates on your list. Supported by innovative MPPT tech to rapidly track and capture the maximum power point of multi wave peak, this MPPT controller delivers up to 94% energy conversion efficiency, higher than 75% of PWM solar controllers. Not only that, but this controller comes packed full of safety protections, including reverse polarity, over-charge/discharge, over load/temperature, backfeeding (night) & short circuit protection. Featuring the cover which protects terminals against corrosion and shorting, this MPPT controller is made of tough ABS housing with upgraded aluminum heat sinks. This durable unit is a great addition to any solar panel system for its multi-stage properties that better support batteries and compatibility with a variety of lead acid deep cycle batteries and LiFePO4 batteries.
  • Premium Energy Harvest: It features conversion efficiency of up to 94%, higher than 75% 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’s performance and increase its lifespan.
  • Upgraded Protection: PV/battery reverse polarity, over-charge/discharge, over load/temperature, backfeeding (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.
