1) Automatic identification of 12V and 24V battery voltage levels.
2) Adopt maximum power point tracking (MPPT) technology to ensure that the solar cell is in the maximum power output state under different environmental conditions, and the energy conversion efficiency is increased by 20-30%.

3) Adopt advanced low-power, high-performance microcontrollers to realize "PWM+SOC" dual intelligent optimized charging control.
4) Intelligent charging management. The three-stage charging method of constant current, constant voltage and floating charge with temperature compensation function is adopted to effectively prolong the service life of the battery; when the battery is over-discharged, it will automatically carry out maintenance charging.
5) Adopt low-loss power MOSFET series PWM soft switch and synchronous rectification technology, the power circuit voltage is reduced, and the working efficiency is high.
6) The connection between the power circuit and the terminal adopts a large cross-section copper bus bar, and the connection is firm and convenient.
8) The protection function is perfect. With functions such as overcharge/overdischarge, short circuit, overload, anti-reverse connection, TVS lightning protection, etc., it is safe and reliable.
9) High-efficiency and super-bright LED indicators are used to visually display the working status and fault status of solar cells, batteries and loads.
