【Wide Compatibility】The solar charger controller with 20A rated discharge current is compatible with 12V or 24V system automatically, suitable for lead-acid batteries: OPEN, AGM, GEL. Dual USB 5V/3A output ports support mobile phones, tablet PCs, or other devices that require 5V voltage.
【Multiple Protection】The 20A solar controller has short-circuited protection, open-circuit protection, reverse protection, over-load protection. Fully 3-stage PWM charge management, improve system efficiency, and prolong the life span of the battery.
【Intelligent Control】The solar controller has perfect SOC function, can control charge current, and supply power to the loads. Prevent the battery from reverse charging to solar panels， over-charging, over-discharging during nights.
【Functional LCD Display】Intuitive LCD that can indicate the status and data can switch modes and parameter configuration, suitable for home, industrial, commercial, etc.
【Easy to Use】The charge controller should connect the battery first, then the solar panel, and finally the load! Dual MOSFET reverse current protection, ultra-low heat.
