20A Solar Controller Solar Panel Battery Regulator 12Volt/24Volt Automatic Identification Solar

This solar recharge controller not only can real-time detect the power of solar panels, but also can tracks the highest voltage current values(VI), which make the system with the highest efficiency for battery recharging.

Features: Use singlechip microcomputer control, has the advantages of intelligent, strong adaptability, and reliable function. Can work in the maximum power point of the I-V curves, the efficiency is up to 99percent . With high accurate temperature detection and compensation circuit, longer battery time. 12Volt/24Volt auto work, three stages of battery display, can intuitively understand of the working status of the controller. Delicate structure design and highly accurate circuit design, allowing the space of the controller to be maximize. With over recharging, over discharging, overload, short circuit and reverse polarity protections. With USB 5V output, can recharge different digital products.
