## Description

It efficiently controls battery charging in 12-24V photovoltaic systems, with MPPT+PWM algorithm for good efficiency and stable charging. The LCD display offers real-time monitoring and complete settings, the integrated protections cover overcharging, discharging and reverse polarity, and the 2 USB ports allow direct powering of mobile devices.
30A solar controller module, MPPT + PWM compatible, designed for efficient and safe battery charging management in 12V or 24V photovoltaic systems. Benefiting from intelligent automatic functions and comprehensive protections, it ensures extended battery life and good conversion efficiency.
It features an LCD display that allows easy access to the main parameters, while the two USB ports allow direct charging of mobile devices. Ideal for residential or mobile applications, this regulator includes advanced temperature compensation technologies and protection against overvoltage, short circuit and wrong connections.
The device can operate in permanent mode or in light mode, based on the light level detected by the solar panel, activating or deactivating the outputs depending on the presence of sunlight. It also allows manual setting of the final voltages (charged-discharged). The controller automatically detects lead-acid and gel batteries, either at 12V or 24V, and in case of using Lithium batteries, it is necessary to check and possibly adjust the final voltages.
It uses a precision industrial chip with 16 A channels and displays real-time temperature, charge/discharge current and voltage.
Charge-discharge parameters are fully adjustable from the LCD screen.
It uses a bidirectional anti-backflow circuit with MOS transistors.
