20A Solar Controller

20A Waterproof MPPT solar controller comes with battery clips and solar connectors, ready to charge the battery, suitable for solar panels with solar connectors.

The Solar charge controller is based on a common negative design and advanced MPPT control algorithm, with intelligent protection against reverse polarity, overcharging, short-circuit, and reverse current.

Compatible with Various Battery options: Sealed, Gel, Flooded, and Lithium-ion.

Feature

• Accessories include standard connector- for solar panels; Anderson connector for pre-wired RV; 20A standard fuse; alligator clamps for car battery or 12 volts lead acid battery.
• Lithium, Liquid, Gel, Flooded, and AGM battery for selection.
• Waterproof design, suitable for indoor, outdoor, camping, boat, and RV use.
• Innovative MPPT technology with High tracking efficiency of up to 99% and peak Conversion efficiency of 98%. Automatically detect 12V or 24V DC system voltages. Four stages charge way: MPPT, boost, equalization, float.
• Dual automatic restriction function when exceeding rated Charging Power and Charging Current. Great for RVs, boats, communication base stations, household systems, field monitoring, etc.
