Solar Inverter

タイトルまたは説明

Product description: this controller is designed for solar LED street light system, internal integration and high precision LED constant current driver chip, can direct drive LED street light, small volume, easy to install, use very convenient. This product is to integrate the solar controller and LED constant current source, adopts the design of high power density, maximum driving **0 w LED street light, the highest efficiency can reach *4%, control accuracy is better than 5%. This controller USES intelligent digital current control technology, through a to adjust current size, cancelled use potentiometer to adjust current value, to avoid the vibration due to the potentiometer deviation, temperature drift and appear error, improves the accuracy and reliability. Support multiple times and LED dimming control, load control more flexible. Has a unique short circuit and meter protection at the same time, full of, discharge automatically shut off, recover fully functional protection measures, such as charging detailed instructions, battery status, load and all kinds of fault indicator. This controller on a computer chip for battery voltage, photovoltaic parameters such as voltage, discharge current, environmental temperature sampling, through the special control model calculation, implementation conforms to the characteristics of battery discharge rate, high accurate control of temperature compensation correction, and using the intelligent and efficient

, a fuzzy charging ways for battery charging PWM 7 sections of voltage control, ensure the battery work in the best condition, greatly extend the service life of the battery.
 

Product function characteristics:

1. The use of microprocessor and special control algorithm, realize the intelligent control.

2. The four load working mode: pure electric, electric + time, manual, and debug mode.

3. The built-in booster type constant current source has high precision, can be directly drive leds, and current is adjustable, convenient to use different lamps and lanterns, and could realize multi-stage adjustable.  

4. Scientific battery management way, when there have been put to raise the voltage of battery charging, a compensation maintenance, normal use, using direct charge and floating charge mode, enhance the service life of the battery; High precision temperature compensation at the same time, makes the control of charge more accurately.

5. Parameters are stored with power function, namely, system model and control parameters, and other important data are stored in the chip inside, no loss after power off, make the adjustment more convenient, the system more reliable.

6. The charging circuit with double MOS tandem control circuit, the circuit is using diode circuits, the voltage is reduced nearly half, charging control, PWM, the charging efficiency is greatly increased, electricity time increase greatly.

7. LED visual display solar battery, the battery and load state, digital tube display to adjust parameters, real-time allows users to understand the status of the system is running, and has a wealth of parameter Settings, users can use according to different environment, set up corresponding working mode.

8. Have overcharge, discharge protection, solar panels, reverse connection protection and TVS lightning protection, no jump line design, can improve the reliability of system durability.

9. All control and precision components, all adopt the industrial-grade chip can normal operation in cold, high temperature, damp environment. At the same time use crystals timing control, timing control and more

And precise.

*0. The use of the digital LED display and Settings, using digital current adjustment, one-click operation can complete all Settings, easy to use intuitive.
