1Introduction to Solar Power Supply Technology

In the current global energy shortage and soaring prices, many countries have adopted preferential policies to encourage the development and application of solar energy technology. Solar powered technology as a solution? Nine or two high-tech technologies were first applied in high-end applications such as aviation exploration. With the promotion of various countries, solar power technology has also undergone rapid development, and solar power generation and solar power technology are increasingly entering civilian applications. Communication in forests, roads, rivers, mountains, and other areas? The application scenarios of 9-1 video electronic devices mainly adopt grid power supply and battery power supply. Battery power supply can often only solve temporary needs and cannot be used as a long-term power supply; However, adopting the power grid supply method has many disadvantages:

The power supply method is cable transmission, which is difficult to construct and costly;

The system maintenance is inconvenient, there are safety hazards in high-pressure transmission, and the operating costs are high;

Difficulty in installation and networking.

The solar power supply system operates without the need for water, oil, gas, or fuel, and can generate electricity as long as there is light. It is a clean, pollution-free renewable energy source that is easy to install and maintain, has a long service life, and can be unmanned. It is highly favored by people and is a leader in new energy. In recent years, the application of solar energy has become increasingly widespread worldwide? 9. In the field, especially in the wilderness, solar power systems are gradually replacing? Some traditional power supply devices are becoming increasingly common.

The solar cell array converts solar energy into electrical energy on clear days, providing power to the load and charging the battery pack; When there is no light, the load is powered by the battery. The solar power supply system consists of a solar cell array composed of solar cell modules, a solar charging control device, an inverter, and a battery pack.

Characteristics of solar monitoring

The use of solar monitoring systems to solve environmental monitoring, forest fire prevention, and power supply problems for highway monitoring equipment has become the fastest, most effective, and convenient solution. No need to install power lines and? 9-2 times of investment, convenient, worry free, safe and reliable; The solar monitoring system does not require manual operation (fully automatic control) and has the characteristics of economy, energy saving, and environmental protection. And what is solar power supply? 9-2 types of clean energy that neither consume resources nor emit pollution, with long service life, stable performance, and low maintenance costs. Is it a national promotion? The new energy of 9-4 is in line with the environmental protection concept of energy conservation, emission reduction, and low-carbon economy.

The solar monitoring system consists of solar modules, a solar charging controller, an inverter, a battery, and a battery box group.

7. Adopting specialized lightning protection technology to ensure stable operation of the system and prevent interference from thunderstorms.

IIIDesign principles for solar power supply

Our company has designed the following power supply sequence based on the characteristics of the solar power supply system:
1. Prioritize DC direct power supply to peripherals, with an energy conversion efficiency of over 98%;
2. Priority should be given to selecting voltage reducing or upgrading modules with a wide voltage range to meet the needs of peripherals and achieve energy conversion of around 70-85%;
3. Only high-power peripherals should choose the right inverter solution, as the energy conversion efficiency of the inverter is the lowest among the three, ranging from 60% to 85%;

4Principles for selecting monitoring systems

Due to the overall construction plan of the solar monitoring system, it mainly involves the power consumption of external devices and the number of consecutive rainy days for power supply. Therefore, the lower the power of the peripheral, the more advantageous it is for the configuration of the solar power supply system. In principle, the more solar photovoltaic panels combined with batteries, the higher the system's failure rate.
Design Misconceptions:
Choose low-priced equipment and then configure the cost of the solar power supply system. This solution may result in high equipment power, leading to increased costs of solar power supply systems, construction, fixed installations, transportation, and the overall construction cost of the system.
Correct thinking:
Guide the design of the entire system based on the total cost of system construction and maintenance. The mainstream monitoring devices on the market do not have the power monitoring function of front-end solar energy systems. Sometimes when the front-end hardware fails to work properly, only personnel are dispatched to the site to investigate the situation. If the solar system loses power on site and cannot be repaired or the cause cannot be identified, especially when the number of solar photovoltaic panels and batteries increases, this situation is prone to occur, leading to a sharp increase in maintenance costs.
Our company's solar monitoring system, based on our own experience in building and maintaining 200 sets of solar monitoring systems in XX territory for 5 years, has improved the design process of the entire solar monitoring system. We have added technologies such as hardware battery power monitoring and switching to low-power mode in low battery mode, ensuring that under the same conditions, we can enhance remote maintenance capabilities, increase equipment dependence on electricity, reduce equipment energy consumption, and thus make the entire solar power supply system more excellent. The characteristics of low construction cost, low maintenance cost, and long duration of continuous rainy weather are achieved.
