With real MPPT solar maximum power point tracking function, automatic intelligent charging management, reduce power loss, low power consumption.

Features:
Adjustable MPPT voltage: users can adjust charging voltage and mppt voltage manually.
Ultra-low power consumption: using ultra-low dropout design to achieve low power consumption and higher conversion efficiency, professionally adapted to solar panels.
Charging method: automatic and intelligent three-stage charging mode. Self-tracking solar power and automatically adjusts the charging current.
Auto-switch: even the weak sunlight in the morning can activate switch, eliminating the need for manual switches.
Charging indicator: red light is on when fast charging; if red light and blue light flash alternately, it is fully charged and will automatically stops charging.
Reverse polarity protection: exclusively designed MOS tube can enable ultra-low dropout for reverse polarity protection, the device will not work in condition of reverse polarity.
Output reflux protection: effectively prevent the backflow from batt-ery to charging board.
Applications: 1W-100W, 9V-28V is suitable for 9V 12V 18V 24V solar panels to charge storage batteries, nickel-cadmium, nickel hydrogen, lithium batteries, wind turbines and solar street lamps.
Better performance: Input and output terminals are made of high-end high-frequency and low-impedance electrolytic capacitors (LOW ESR), ensuring that the output ripple can effectively filter out the switching power supply glitches.

Note: For the first charge, please adjust the output voltage in advance and closely monitor the batt-ery voltage to prevent overcharging! Do not charge unprotected lithium batteries!
