1. Industrial-grade main control chip, 16-level AD sampling accuracy, accurate real-time display of temperature, charging current, and discharging current, and the cumulative power neration is clear at a glance 2. Auto MPPT tracking charging, high charging efficiency, non-stop detection during the charging process two-way tracking. Input 15V to 40V boost MPPT for efficient charging. 3. Lar-screen LCD display, adjustable charging and discharging parameters UItra-wide char and dischar can be adjusted. As long as you understand the characteristics of the battery and set its corresponding charging parameters, you can char any battery. The output power off minute and hour can be adjusted, which is more convenient (the market only has no minute adjustment) 4. Complete 3-sta char manament, effectively protect the battery, and the battery is more .This controller is suitable for all kinds of lead-acid batteries (including open, sealed, and colloida. Lithium batteries require user-defined parameters). 5.To char the 12V/24V/36V/48V/60V battery, the volta value of the solar panel is 1.5 times the volta value of the battery to be rechard.
