12V/24V adaptive solar charge controller with MPPT technology and multiple protection functions (40A)

【Automatic Adjustment】This solar charge controller automatically adjusts to 12V/24V batteries and is compatible with both lead-acid and lithium batteries. Innovative MPPT Technology: The controller uses MPPT technology to determine the maximum charging current and ensure up to 99% efficiency. Unlike other MPPT technologies that rely on automatic top-up charging or the solar panel voltage, our MPPT solar charge controller determines the maximum charging current. 【Multiple Protections】The solar charge controller is equipped with short-circuit, reverse polarity, and overload protections to ensure system safety. The charge controller must be connected first to the battery, then to the solar panel, and finally to the load. Efficient Charge Management: With its 3-stage PWM charge management, this solar charge controller improves system efficiency and extends battery life. Accurate display and lifetime technical support: The industrial microcontroller offers 16-bit AD sampling accuracy and accurately displays temperature, charging current, and discharging current in real time.
