MPPT Solar Charge Controller 15A 12V/24V Battery Regulator IP68
If you’ve been searching for a solar controller that reigns supremacy in energy conversion, this MPPT controller by ATEM POWER must be the top candidates on your list. This IP-68 rated MPPT controller, supported by ATEM POWER’s patented tracking tech to rapidly track and capture the maximum power point of multi wave peak through 3 tracking algorithms, delivers higher energy conversion efficiency of up to 96% than 75% by PWM. Not only that, this controller is shade-resistant and will intelligently achieve full charge. It includes bulk, absorption and float properties to better support and increase battery’s lifespan, and its temperature sensor automatically detects ambient temperature to adjust its performance, which can significantly improves safety during operation and makes charging more efficient. And it is compatible with lead acid battery (SLA, AGM, OPEN and GEL) and lithium battery ( Li(LiCoMn)O2 and LiFePO4) with dedicated charging algorithm for the latter.
Maximize Energy Harvest: It features conversion efficiency of up to 96% and will intelligently achieve full charge, especially during cloudy days or poor weather.
Patented Tracking Tech: The maximum power point of multi wave peak will always be rapidly and automatically captured through 3 patented tracking algorithms.
Highly Compatible: It is compatible with lead acid battery (SLA, AGM, OPEN and GEL) and lithium battery ( Li(LiCoMn)O2 and LiFePO4).
3-Stage Charging: A 3-stage algorithm, bulk, absorption and float charge, is designed to enhance battery’s performance and increase its lifespan.
Temperature Compensation: A sensor is designed to automatically adjust its performance, making charging in extreme temperatures safer and more efficient.
Lithium Charging Algorithm: Pre-charge/BMS monitoring, constant voltage activation and regulated voltage control are integrated to fully protect lithium battery.
Upgraded Protection: PV/battery reverse polarity, over-charge/discharge, over load/temperature, backfeeding(night), lightning,short circuit protection are embedded.
Durable Construction: Sturdy aluminum housing is impact and shock resistant, and IP-68 protection ensures all weather dependability.
Rapid Heat Dissipation: The upgraded heat sinks are designed to rapidly dissipate heat for smoother operation against high ambient temperatures.
