Lighting & time control 15A 12V solar power controller

Product Description

Main Features

1. Intelligent control is realized by using microprocessor and dedicated control calculation.

2. Four load working modes: Pure lighting control, lighting control & timing control, hand operation and debug mode.

3. Advanced switching function of commercial power complementation. By connecting commercial power with the load directly instead of linking with battery, the damage to the battery and current source is decreased to a large extent. Besides, the allocation for the current source of commercial power will be optimized. This soft switching makes no impact to the load and battery, thus to influence to the performance of load.

4. Detection of commercial power. The battery voltage decrease to the switching point voltage and the commercial power is on. While without the commercial power, batty discharges till the charge resumption set-point and the output is off.

5. Scientific management of battery: as it is overcharged, the battery will get booster tension charge. As a result compulsory maintenance is available for the battery. In normal working state, the direct charge and floating charge are both available, so that the battery life-span is increased. Besides, the adoption of high precision temperature compensation makes the charging more accurate.

6. Comparing with the charging loops using diodes, the one that adopts double MOS series circuit control makes the voltage loss dropped by 50%. With the PWM fuzzy control in charging, the charge efficiency is improved a lot.

7. LED screen shows the working state of solar battery, storage battery and load. LED shows the adjusted parameter. In this way, users can lean the operation state in ream time. Besides, there are various choices for parameter, users can select the proper working mode base on the different conditions.

8. Various protections include over-charge, over-discharge and over-load, as well as unique electron short circuit protection and connection-reverser protection. All the protections are harmless to any parts and fuse. TVS thunder proof protection is also available. Non wire jumpers design improves the reliability and durability of the products.

9. Technical grade chips and precision components are adopted for all the controls. Therefore, the controller performs well in very low and high temperature, as well as humid environment. At the same time, with the use of crystal timing control, the timing function of controller is much more reliable.

10. Double digital LED display.

FAQ

Phenomenon	Solution
Under the sunshine, the indicator light (NO. 1) of solar panel is off	Please check the line connected to photocell and make sure the proper connection
As the cell panel is charged, the indicator light (NO. 1) flashes quickly	The system is over-voltage. Please check whether the storage battery is well connected, or its voltage is too high
The indicator light (NO.2) of storage battery is off	Please check whether the storage battery is well connected
The indicator light (NO.2) of storage battery flashes quickly without output	The storage battery is over-discharged
The indicator light (NO.3) of load flashes slowly without output	The load power is higher than the rated power. Please stop the operation of some equipment which consumes power, and then press the key for a long time
The indicator light (NO. 3) of load flashes quickly without output	The load is short circuit and need to be adjusted. Then press the key for a longer time or wait till the next day, it will restart to work
The indicator light (NO. 3) is on continually without output	Please check whether the equipment which consumes power is well connected
Others	Please check the connection, 12V/24V Auto identified
