Temperature requirements
Generally speaking, the working temperature range of wind solar complementary controllers is usually between -20 ℃ and 50 ℃, which is more suitable. In low-temperature environments, such as below -20 ℃, the performance of electronic components may be affected. For example, the capacitance value of capacitors may change, and the conductivity of semiconductor devices may also change, which may lead to a decrease in control accuracy and a slower response speed of the controller. In high temperature environments, when the temperature exceeds 50 ℃, the integrated circuit chips inside the controller may experience overheating. Long term exposure to high temperatures can accelerate the aging of electronic components, and may even lead to chip damage, circuit short circuits, and other issues.
For wind solar complementary controllers installed in cold regions (such as high-altitude mountainous areas or near polar regions), appropriate insulation measures need to be taken, such as wrapping the controller in an insulated box and installing a small heating device inside the box to ensure that the controller can work normally in low-temperature environments. In hot desert areas or low latitude tropical regions, attention should be paid to the heat dissipation of the controller. The controller can be installed in a well ventilated location, or heat sinks can be installed on the controller’s casing to reduce its internal temperature.
Humidity requirements
Wind solar complementary controllers are typically required to be used in environments with relative humidity not exceeding 90%. High humidity environments may cause condensation inside the controller. When water vapor in the air condenses into water droplets on the surface of the controller’s circuit board or electronic components, it may cause a short circuit fault. For example, if a water droplet connects two adjacent conductive lines on a circuit board, it will form a short circuit and damage the controller. Moreover, high humidity environments can accelerate the corrosion of metal components, such as solder joints on circuit boards and metal connectors for connecting wires. These corroded components may experience issues such as poor contact, which can affect the normal functioning of the controller.
When using a wind solar complementary controller in humid coastal areas or rainy tropical jungle areas, it is necessary to perform moisture-proof treatment on the controller. The controller can be installed in a cabinet with good sealing performance, and desiccants such as silicone desiccants can be placed inside the cabinet to absorb moisture from the air and reduce the humidity inside the cabinet.
Installation location requirements
From the perspective of lighting, for the wind solar complementary power generation system where the wind solar complementary controller is located, the solar panels need to be installed in a sunny and unobstructed position. The controller should be installed near the solar panels and wind turbines to reduce line losses. For example, when installing a wind solar complementary power generation system on the roof of a building, the solar panels should face south (in the northern hemisphere) and there should be no tall buildings, trees, or other obstructions around them. The controller can be installed in the rooftop computer room or near the solar panels and wind turbines.
From the perspective of electromagnetic interference, it is advisable to avoid installing controllers in environments with strong electromagnetic interference as much as possible. For example, do not install it near large motors, transformers, and other equipment. Because strong electromagnetic interference may affect the internal circuit signals of the controller, leading to errors in its control of wind and solar power generation. If there is a possibility of misjudging parameters such as wind speed and light intensity, it may affect the normal operation of the entire power generation system.
Requirements for dust and sandstorm environment
For wind solar complementary controllers installed in areas with high dust or sandstorms (such as desert edges or near construction sites), dust prevention measures need to be considered. Excessive dust accumulation on the heat dissipation holes of the controller or the surface of the circuit board can affect the heat dissipation effect and circuit performance. For example, dust may hinder air circulation, preventing the heat inside the controller from dissipating in a timely manner. Moreover, if the dust contains conductive substances, it may also cause short circuit faults.
The controller can be installed in a cabinet with dust-proof function and regularly cleaned of dust inside the cabinet. In areas with strong sandstorms, the sealing of cabinets should be better, and filters can be installed at the air inlet and outlet to filter out dust particles.
