1. Industrial master chip, 16 AD sampling accuracy, temperature, charging current, discharge current accurate real-time display, power generation at a glance. 2. Automatic focusing MPPT tracking charging, high charging efficiency, uninterrupted detection during charging, bidirectional focusing tracking. 3. -screen LCD display, adjustable charging and discharging parameters. Ultra-wide charging and discharging adjustable, as long as you understand the battery characteristics, set the corresponding charging parameters, you can charge any battery. When the output is off, the time can be adjusted, which is more convenient. (on the market there is no point adjustment). 4. A complete three-stage charging management, effectively protects the battery, the battery is more durable. 5. Built-in overheating, overcurrent short circuit, circuit break protection, reverse connection protection, when the fault is eliminated, the controller automatically restores, does not damage the device. 6. Bidirectional MoS tube anti-backflow circuit, high power charging mode, ultra-low heat. 7. R5.0 solar charging DC connector, R5.0 DC lamp output DC connector, convenient connection. Specifications 1. Rated voltage: 12/24V 2. Rated current: 30/40/50/60/100A 3. Max. PV voltage: 50V 4. Max. PV input power: 750W(12V) / 1500W(24V) Function: 1. Always keep the battery at a full charge state. 2. Prevent the battery from overcharging. 3. Prevent the battery from over-discharging. 4. Prevent the battery from discharging to solar panels during nights. 5. Reverse polarity protection for battery 6. Reverse polarity protection for solar panels 7. When the battery voltage is low, the controller will automatically disconnect the load from the system. If the battery voltage returns to normal, the load will work. 8. Lightning protection 9. According to the battery voltage grade, the controller can automatically set the charge cut-off voltage, load cut-off voltage, load recovery voltage. (The parameter is default under 25 condition, locked by CPU procedure, cannot be adjusted.) 10. The controller automatically compensates the charging voltage temperature according to the ambient temperature changes.
