Product Description
12V/24V 5A Waterproof Solar Charge Controller with LED Digital Display (QWP-145WP2)

1. Characteristics

1. IP68 waterproof rating, aluminum design, can effectively prevent all forms of corrosion.
2.12V/24V automatic identification system voltage.
3. LED digital display and waterproof keyboard operation, using simple and quick.
4. Improved three-step charging algorithm, once a week the battery equalizing charge, effectively prevent the battery inequality and sulfuration, improve battery life.
5. Five kinds of loading modes, easy to use in a variety of lights and control equipment.
6. External temperature sensors with high accuracy temperature compensation.
7. Parameter settings to save power-down function, without duplication, easy to use and quick.
8. Various status indicators.
9. Over-charges, over discharge, short circuit protection and overload protection as well as electronic protection against reverse polarity.
10. TVS lightning protection.

2. Installation and wiring
The controller mounted to firm, size is as follows:
Overall size: 65 x 67 x 18 (mm)
Installation size: 44 x 76 (mm)
Installation aperture: 3.5 (mm)

3. Safety recommendations
1. Do not immerse the controller with a corrosive liquid, it will damage the controller and produce harmful gases.
2. In connection 24V system, the battery terminal voltage may exceed the body panels safe voltage when required, pay attention to use insulated tools, and to ensure that your hands dry.
3. Battery reversed, the controller does not damaged, but the load will have a negative voltage output, the voltage of the load may damage your device, when used to prevent this from happening.
4. In the 24V system, if one end of the battery or solar panel is likely to reverse damage to the controller.
5. There is a lot of battery energy storage, in any case must not let battery short circuit; We recommend that the battery on the series fuse.
6. Battery may produce combustible gas, stay away from sparks.
7. Please ensure that children stay away from the battery and controller.
8. Follow the battery manufacturer's safety recommendations
