1. Outdoor application of solar photovoltaic power generation system
   Case background: In remote areas or places not covered by the power grid, such as rural areas, mountains, islands, etc., solar photovoltaic power generation system is an effective solution to provide stable power.
   Solution：The photovoltaic grid-connected inverter uses a metal housing, has IP65 protection grade, and supports the operating temperature range of -40~65℃, which can meet the needs of outdoor applications. The inverter has a maximum output power of 250W and an output voltage of 220V, which is suitable for small households or individual users. It is also equipped with efficient power conversion technology to ensure stable operation in all weather conditions. For example, in the large photovoltaic power station project in Dunhuang, the 1500V photovoltaic inverter provided by Goodway not only has excellent overdistribution capability, but also can effectively increase the power generation and save the project kilowatt-hour power cost.

2. Application of portable energy storage inverter in camping and hiking
   Case background: For people who like outdoor activities, such as camping, hiking, fishing, etc., carrying a portable energy storage inverter can provide reliable power support for mobile phones, cameras, laptops and other electronic devices.
   Solution: The outdoor power supply launched by Openg has a built-in 299Wh lithium iron phosphate battery, which supports 600W output power and can withstand 1200W peak output power. This power supply has UPS function and can be switched to outdoor power supply within 15ms, ensuring that the equipment will not be damaged by sudden power failure. In addition, it also has waterproof, dustproof, seismic and other characteristics, suitable for use in harsh environments. Similar portable energy storage inverters can also provide power for electric kettles and small refrigerators for picnic, greatly enhancing the convenience of outdoor life.

3. Electricity supply for RV trips
   Case background: RV travel is becoming more and more popular, but how to provide stable power to the various appliances inside the RV without an external power source is a challenge.
   Solutions: Some high-end motorhomes are equipped with specially designed vehicle inverters, such as Green Link 150W vehicle inverters, which can not only provide AC power for 12V DC appliances in the car, but also support PD fast charge output, high power density, especially suitable for long-term outdoor activities to power various electronic devices. In addition, there are some high-power inverters that can be directly connected to the car battery to provide stable power support for more powerful appliances such as car refrigerators, microwave ovens, etc. For example, Shenghong household storage successfully delivered the domestic 4700 meters high altitude household energy storage system project, and its household energy storage inverter ISUNA 20000T successfully broke through the restrictions of the extreme harsh environment on the plateau, showing excellent performance and stable operation.

4. Power guarantee in emergency rescue
   Case background: After natural disasters, such as earthquakes and floods, infrastructure is often damaged and power supply is interrupted, which affects the development of rescue work.
   Solution: Outdoor power plays an important role in emergency rescue, providing emergency power support for medical equipment, communication equipment, lighting fixtures, etc. For example, the Gallium nitride (GaN) 4kW high power fanless bidirectional inverter technology platform developed by Zhuhai Gallium Future Technology Co., Ltd. adopts the advanced CCM BTP PFC topology + Full bridge LLC soft switch topology + SR synchronous rectification, supporting 180Vac~264Vac on the AC side. Dc side is 43.2Vdc~56Vdc, continuous power is 4kW, PFC switching frequency is 60KHz, LLC resonant frequency is 100KHz, compact size, unit: mm. This inverter is not only efficient, but also does not require fan heat dissipation, avoids dust and water vapor entry, improves reliability and safety, and is very suitable for emergency rescue scenarios.

5. Photovoltaic pump system in agricultural irrigation
   Case background: In agricultural production, especially in arid or water-scarce areas, traditional diesel-powered pumps are costly and environmentally polluting. Photovoltaic pump systems are an environmentally friendly and economical option.
   解决方案：High protection photovoltaic pump special inverter is based on GD series of high-performance vector inverter core control algorithm, combined with photovoltaic pump application control requirements developed products. The inverter has a high level of protection, can be long-term stable operation in harsh outdoor environment, suitable for solar powered pump system. The solar energy is converted into electricity by photovoltaic modules, and then the pump is driven by the inverter, which realizes the efficient use of green energy, reduces the production cost of farmers, and also reduces the impact on the environment.

6. Off-grid photovoltaic energy storage power supply system in outdoor construction
   Case background: In the process of outdoor construction, power tools and living facilities need continuous and stable power supply, and traditional diesel generator sets have problems such as inconvenient refueling and poor power quality.
   Solution: Optical storage AC off-grid power supply system adopts integrated DC bus technology, organically combines photovoltaic power generation system, battery energy storage subsystem, DC distribution system, etc., makes full use of clean and green energy generated by solar energy, and stably supplies power to household appliances. The system not only solves the problem of difficult refueling of diesel generator set, but also provides high-quality electric energy and prolongs the service life of power tools. The system is designed to be lightweight, easy to assemble, and can be reused in different locations, especially for off-grid construction sites.

7. Outdoor inverter applications in extremely cold conditions
    Low temperature may lead to changes in the physical characteristics of electronic components, affecting the normal operation of the inverter.
   All inverter types of Chint power supply have passed environmental tests such as high temperature, high humidity, and high and low temperature cycle (-40℃ ~ +60℃) to ensure stable operation under extremely cold conditions. For example, in the grid-connected series photovoltaic project in Jilin Baicheng, Chint Power's 250kW super-power series inverter adopts a no-screen design scheme, and the needs of low-temperature design are also considered in the selection of plastic parts, fundamentally eliminating the occurrence of problems.

In summary, the outdoor application of inverter products is not limited to simple power conversion, but into the actual needs of various fields, from solar power generation to emergency rescue, from RV travel to agricultural irrigation, are playing an irreplaceable role. With the introduction of advanced inverter technology, outdoor activities and operations become more convenient, safe and environmentally friendly.
