Solar controller lithium battery 3 string 11.1V 12V lithium battery special waterproof controller
1) Intelligent control is realized by using microprocessor and special control algorithm. 2) Light control / light control + time control / debugging / normally open / morning light mode, 3) Scientific battery management method. When over-discharge occurs, the battery is charged with boosted voltage and compensated for maintenance. During normal use, the combination of direct charging and floating charging is used to increase the service life of the battery; at the same time High-precision temperature compensation makes charging control more accurate. 4) This product is suitable for lead-acid batteries and lithium batteries, and can set parameters for infrared remote controllers 5) The parameter setting has the function of saving after power-off, that is, important data such as system mode and control parameters are saved inside the chip, and it will not be lost after power-off, which makes the adjustment more convenient and the system work more reliable. 6) The charging circuit adopts a double MOS series control loop, which reduces the circuit voltage loss by nearly half compared with the circuit using diodes. The charging uses PWM fuzzy control, which greatly improves the charging efficiency and greatly increases the power consumption time. 7) With overcharge and over discharge protection, solar panel reverse connection protection and TVS lightning protection, no jumper design, which can improve the reliability and durability of the system. 8) All the control adopts industrial grade chips and precision components, which can operate normally in cold, high temperature and humid environment.
Local system products automatically recognize the system voltage of 12V and 24V and 3 strings and 4 strings of lithium batteries. The controller sets its parameters through an infrared force controller. The operation is simple, and it has unique short-circuit and anti-reverse protection, full-function protection measures such as automatic shutdown and recovery of full discharge, over-discharge, detailed charging instructions, battery status, load and various fault indications. The controller samples the battery voltage, photovoltaic cell voltage, discharge current, ambient temperature and other parameters through a computer chip, and calculates it through a special control model to achieve highly accurate control of the discharge rate and temperature compensation correction in accordance with the characteristics of the battery, and uses intelligent and efficient The PWMA fuzzy charging method charges the battery to ensure that the battery works in the best state, greatly extending the service life of the battery.
Installation and use
1. The controller should be installed firmly. 2. Wire preparation: Use a cable that matches the current, plan the length, strip the 5mm insulation from the connector on the side of the controller, and reduce the length of the connecting wire as much as possible to reduce electrical losses. 3. Connect the battery first: pay attention to ten and one pole, don't reverse it. If the connection is correct, the battery indicator will light, otherwise, you need to check whether the connection is correct. 4. Reconnect the load: Connect the LED load cable to the load output of the controller. Pay attention to the + and-poles and do not connect them in reverse to avoid damage to the device. 5. Connect the solar panel again: pay attention to ten poles and one pole, don't reverse it. If there is sunlight, the solar panel indicator will be on, otherwise, you need to check whether the connection is correct.
