Technical Specifications:


=======================================
Description:
The controller is specially designed for solar power systems DC, solar power street lamp systems, and mini solar power stations. Intelligent control is realized using specialized computer chips. The controller can be used in harsh conditions, as it uses technical-grade chips. This controller automatically identifies 12V/24V batteries.
Short circuit, overload, reverse connection protection, as well as overcharge and discharge protection are available. In addition, complete indications are available, including indications for charging state, battery storage, and faults.
Using computer chips, the controllers sample parameters of battery voltage, photovoltaic cell, discharging current, and ambient temperature, and then utilize specialized control calculation mode to manage the discharge rate and adjust it to battery characteristics, ensuring precise temperature compensation. PWM fuzzy charging mode and 7-stage voltage regulation are available for storage batteries, keeping batteries in peak working condition. Various operating modes of the controller can meet different customer requirements.
Main Features:
- Intelligent control is realized through a microprocessor and specialized control calculations.
- Four working modes: pure lighting, lighting control and timing, manual operation, and test mode.
- Scientific battery management: when overcharging, batteries are charged with increased voltage. This allows necessary maintenance for the battery. Both direct charging and floating charging are possible in normal operating mode, increasing battery lifespan. Additionally, the use of high-precision temperature compensation makes charging more accurate.
- Compared to charging loops using diodes, charging circuitry using dual MOS series reduces voltage drop by 50%. With PWM fuzzy control during charging, charging efficiency has significantly increased.
- The LED display shows the working status of the solar battery, storage battery, and load. The LED displays adjusted parameters, allowing users to check operational status in real time. Various parameter options are also available; users can select the appropriate working mode based on different conditions.
- Various protections include overcharge, discharge, overload protection, as well as specific electronic short-circuit and reverse connection protections. All protections are harmless to any parts and fuses; the fuse is just the final protection of the controller itself against short circuit. The connector-free design enhances product reliability and durability.
- All controls feature industrial-grade chips and precision components. Thus, the controller performs well in very low and high temperatures, as well as humid environments. Simultaneously, the use of crystal timing control makes the controller’s timing function much more reliable.
- When using larger diameter terminals, wires up to 6 mm² (0.0093 in²) can be secured.
- The parameter is set to energy-saving mode; system model and control parameters, along with other critical data, are stored within the chip, which do not get lost after power-off, allowing for more convenient and reliable system adjustments.
- With two digital LED displays and settings, all configurations can be completed with a single button, making it intuitive and easy to use.
