TRANSFORMER Short-circuting Reverse-current Overcharging Overload Over-discharging Reverse polarity protection FAN COOLING Good Heat Gissipation Intelligence Fan-on temperature >45℃ and off < 40℃ , let your controller feel cooling. Fan use BEARING technologies increase life UP TO 5000hrs in normal use. PORTS DESIGN We consider that the larger diameter of the wire will be greater cost for customers, so we designed two connectors for each pos and negs on solar and batteries connectors Read more MPPT technology Automatically detect 12V or 24V DC system voltages Innovative MPPT technology with high tracking efficiency up to 99% and peak conversion efficiency of 98% Various optional batteries Deep cycle Sealed, Gel, Flooded and Lithium (12.8V LFP) battery option ready Charges over-discharged lithium batteries Protection System Electronic protection: Overcharging, over-discharging, overload, and short circuit. Reverse protection: Any combination of solar module and battery, without causing damage to any component Customize charge controller Customizable charging voltages Positive ground charge controller Read more HOW TO WIRE YOUR SOLAR CONTROLLER? Turn the adjusting screw counterclockwise until the plate moves downward. Please peel off the coating of the cable tip by about 8 to 10 mm，Then Insert the wire into the new opening between the plate and the "top" of the terminal hole. When turning the adjuster clockwise, the plate moves upward and crushes the wire in the hole of the terminal. Make sure all connections going into and from the controller are tight. IMPORTANT NOTE: Make sure your battery must be atleast 60% charged prior to connecting to controller. Always connect your battery first Never connect your solar panel array to the controller without a battery. Careful your input power and voltage does not exceed the max. 100A MPPT Solar Controller 12V 24V 36V 48V PV 150V MAX 5000W 100A MPPT Solar Controller 12V 24V PV 100V MAX 2600W 80A MPPT Solar Controller 12V 24V PV 100V MAX 2000W 60A MPPT Solar Controller 12V 24V PV 100V MAX 1500W LCD 485 Battery System Voltage 12V 24V 36V 48V 12V 24V 12V 24V 12V 24V Rated Current 100A 100A 80A 60A Max Input Power 5000W 2600W 2000W 1500W
