Z-section steel is a common cold-formed thin-walled section steel, the thickness is generally between 1.6-3.0mm, and the section height is mostly between 120-350mm. The processing material is hot-rolled (painted), galvanized. The processing standard shall be implemented according to GB50018-2002. Z-section steel is usually used in large-scale steel structure workshops. The processing length and holes are produced according to the processing requirements.

Ancillary products: color steel tile; rock wool sandwich panel; floor deck, etc.

The main purpose of Z-section steel

Cold-formed Z-shaped steel has the advantages of adjustable size and high compressive strength. It is widely used in automobiles, railway vehicles, building doors and windows, transportation, shelves, electrical cabinets, highway guardrails, building steel structures, containers, steel formwork and scaffolding, solar energy Support shipbuilding, bridges, transmission towers, steel sheet piles, cable bridges, agricultural machinery, furniture, storage, guide rails, keel steel, vegetable greenhouses, pipeline supports, municipal construction and other fields.3. Distributed photovoltaic power generation system, also known as distributed power generation or distributed energy supply, refers to the configuration of a smaller photovoltaic power generation power supply system at the user site or near the power site to meet the needs of specific users and support the existing distribution network. economic operation, or meet the requirements of both aspects at the same time.

Stainless steel z section is important. The function of the solar panel is to convert the light energy of the sun into electrical energy, and then output the direct current and store it in the battery. The solar panel is one of the most important components in the solar photovoltaic system, and its conversion rate and service life are important factors that determine whether the solar cell has use value. Component design: Designed according to the requirements of the International Electrotechnical Commission IEC: 61215: 2015 standard, 36 or 72 polycrystalline silicon solar cells are used in series to form various types of 12V and 24V components. The module can be used in various household photovoltaic systems, independent photovoltaic power plants and grid-connected photovoltaic power plants.

Features of raw materials: Cells: Encapsulated with high-efficiency (above 16.5%) monocrystalline silicon solar cells to ensure sufficient power generation of solar panels. Glass: Low-iron tempered suede glass (also known as white glass), with a thickness of 3.2mm, has a light transmittance of more than 91% in the wavelength range of solar cell spectral response (320-1100nm). For infrared light greater than 1200 nm have higher reflectivity. At the same time, the glass can withstand the radiation of solar ultraviolet rays, and the light transmittance does not decrease. EVA: A high-quality EVA film layer with a thickness of 0.78mm added with anti-ultraviolet agent, antioxidant and curing agent is used as the sealing agent of solar cells and the connecting agent between glass and TPT. Has high transmittance and anti-aging ability. TPT: The back cover of the solar cell - the fluoroplastic film is white and reflects the sunlight, so the efficiency of the module is slightly improved, and because of its high infrared emissivity, it can also reduce the operating temperature of the module, also Conducive to improving the efficiency of components. Of course, the fluoroplastic film first has the basic requirements of aging resistance, corrosion resistance, airtightness, etc. required by solar cell packaging materials. Frame: The aluminum alloy frame used has high strength and strong resistance to mechanical impact. It is also the most valuable part of a solar photovoltaic system. Its function is to convert the radiation capacity of the sun into electrical energy, or send it to the battery for storage, or drive the load to work.

controller

The solar controller is composed of a dedicated processor CPU, electronic components, displays, switching power tubes, etc.

main feature:

1. The use of single-chip microcomputer and special software realizes intelligent control;

2. Accurate discharge control using battery discharge rate characteristic correction. The end-of-discharge voltage is a control point corrected by the discharge rate curve, which eliminates the inaccuracy of simple voltage control over-discharge, and conforms to the inherent characteristics of the battery, that is, different discharge rates have different end-of-life voltages.

3. It has automatic control such as overcharge, overdischarge, electronic short circuit, overload protection, and unique anti-reverse connection protection; the above protection does not damage any components and does not burn insurance;

4. The series PWM charging main circuit is adopted, which reduces the voltage loss of the charging circuit by nearly half compared with the charging circuit using diodes, and the charging efficiency is 3%-6% higher than that of non-PWM, which increases the power consumption time; the improvement of over-discharge recovery Charging, normal direct charging, and automatic control of floating charging make the system have a longer service life; at the same time, it has high-precision temperature compensation;

5. The intuitive LED light-emitting tube indicates the current battery status, allowing users to understand the usage status;

6. All controls use industrial-grade chips (only for industrial-grade controllers with I), which can run freely in cold, high temperature, and humid environments. At the same time, the crystal oscillator timing control is used, and the timing control is precise.

7. The potentiometer adjustment control set point is canceled, and the E-square memory is used to record each working control point, which digitizes the setting and eliminates the error of the control point due to the vibration deviation and temperature drift of the potentiometer, which reduces the accuracy and reliability. sexual factors;

8. The digital LED display and setting are used, and all settings can be completed by one-button operation. The function of extremely convenient and intuitive use is to control the working state of the entire system, and to protect the battery from overcharge and overdischarge. In places with large temperature difference, a qualified controller should also have the function of temperature compensation. Other additional functions such as light-controlled switches and time-controlled switches should be optional for the controller;

battery

The function of the battery is to store the electrical energy emitted by the solar panel when there is light, and release it when needed. Solar battery is the application of 'battery' in solar photovoltaic power generation. There are four types of lead-acid maintenance-free batteries, ordinary lead-acid batteries, gel batteries and alkaline nickel-cadmium batteries. The solar batteries that are widely used in China are mainly lead-acid maintenance-free batteries and gel batteries. These two types of batteries, because of their inherent "free" maintenance characteristics and the characteristics of less pollution to the environment, are very suitable for reliable solar energy. Power systems, especially unattended workstations.

Inverter

The direct output of solar energy is generally 12VDC, 24VDC, 48VDC. In order to provide power to 220VAC electrical appliances, it is necessary to convert the DC power generated by the solar photovoltaic system into AC power, so a DC-AC inverter is required.
