Properties of the solar charge controller
1. Design for off-grid solar power system.
2. Applicable to different kinds of batteries.
3. Adopts MPPT technology (Maximum Power Point Tracking). The advanced tracking algorithm make the solar module operate at ideal voltage which the solar modules can produce the maximum available power.
4. Modular design with simple structure and easy maintenance.
5. Automatic power control function.
6. LCD display: Solar panel current, solar panel voltage, solar panel power, battery group voltage, charge current.
7. Perfect protection function: Solar reverse charge protection, Solar reverse connection protection, Battery reverse connection protection, Battery overcharge protection, Battery over current protection etc ,thus the system has higher reliability.

- Q:Solar controller 10a, a represents what
- In addition, the general controller will be marked as single-phase or three-phase power, according to P = UI (power = voltage * current) this formula, you can infer the corresponding power, in the choice of output devices (such as pumps) can not exceed this power.
- Q:What is the system voltage of the solar controller?
- General solar energy is now used LED lights, because the solar power is limited, with LED more power, the general 3, 4 watts when the general lights a 20 watts of brightness.
- Q:Solar controller use
- The controller as a core component of solar energy must be a reliable product, otherwise no matter how good the solar system can not play its due role.
- Q:Solar controller one machine how
- First of all, if you are using a multifunctional VRV system, triple the (air conditioning, to warm, hot water) together, then connect the solar energy, solar energy is auxiliary equipment, can not be set as the main control equipment. Finally, I would like to ask, your one machine is a computer or I said one machine
- Q:What is the meaning of the 30A solar controller?
- This 30A proves that the controller has a maximum current of 30A.
- Q:What is a solar controller?
- Solar controller uses high-speed CPU microprocessor and high-precision A / D analog-to-digital converter, is a computer data acquisition and monitoring and control system. It can collect the working data of the PV station in real time, obtain the working information of the PV station at any time, and accumulate the historical data of the PV station in detail, and provide the accurate and reliable evaluation of the reliability of the PV system design and the reliability of the quality of the inspection system Full basis. In addition, the solar controller also has a serial communication data transmission function, can be a number of photovoltaic systems sub-station for centralized management and remote control.
- Q:Solar controller red light flashing
- Solar controller is divided into a variety of types, the lights are also representative of the battery, battery components and load, you said the red light flash is the end of the indicator light. You can also look for the controller's instructions, the above will generally refer to the reasons for the light flash.
- Q:A solar controller 12v20A battery 12v 20A Will the need for a few watts of solar panels can be normal charge
- Solar controller is called solar charge and discharge controller, is used in solar power system, the control of multi-channel solar cell battery charging and battery to the solar inverter load power supply automatic control equipment.
- Q:What are the solar controller models?
- This situation is best to contact the manufacturers, generally have PDF version of the manual. You can contact the manufacturer to an electronic version of the manual.
- Q:Choose a solar controller which need to have a few conditions
- According to your specific application environment, first determine whether to select the charge controller or charge and discharge controller. Two applications of input and output power level, the input power is mainly solar panels, and the controller is basically in accordance with the current to count. For example, 12V system 120 wrench that should be selected at least rated 10A controller. While the actual system current 7A or so is the other security margin.
