New mobile off-grid power solutions

As an innovative off-grid power equipment, folding photovoltaic containers are emerging with their unique advantages and huge potential.

First, the internal structure of the folding photovoltaic container
The interior of the folded photovoltaic container is not just a folded photovoltaic panel. First, it is equipped with an efficient folding photovoltaic array, using TOPCon double-sided photovoltaic panels with high conversion efficiency and good stability, which can maximize the capture of solar energy and convert it into electricity under different lighting conditions.
In addition to the photovoltaic panel, there is also a built-in intelligent inverter, which is one of the core components of the entire system. It is responsible for converting the direct current generated by photovoltaic panels into alternating current to meet the needs of various conventional electrical equipment.
In order to store excess power, a large-capacity lithium battery pack is installed in the box. Lithium batteries have the advantages of high energy density, high charge and discharge efficiency, long service life, etc., and can continuously supply power to the load in the case of insufficient light or night to ensure uninterrupted power supply.
In addition, a comprehensive energy management system (EMS) is integrated into the box. EMS can monitor the power generation power of the photovoltaic panel in real time, the power of the battery pack and the charging and discharging state, the operating parameters of the inverter and the power consumption of the load. Through the collection and analysis of these data, EMS can realize the intelligent control and optimal management of the entire power system, rationally distribute the charge and discharge current of the battery pack, prevent overcharge and overdischarge, extend the battery life, and ensure that the electrical equipment obtains a stable and safe power supply.

Second,Folding photovoltaic containers have become the three major advantages of off-grid power solutions
1. Convenient mobility
Folding photovoltaic containers are designed to meet the power needs of various complex terrains and remote areas. Its compact folding structure and the dimensions of a standard container make it easy to transport by road, rail, sea and even air. Whether it is the construction of communication base stations in mountainous areas, the electricity of residents in remote islands, or the temporary power supply of field construction camps, it can be quickly transported to the designated location, greatly expanding the coverage of power supply, and solving the off-grid electricity problem that is difficult to reach the traditional fixed power station.
2. Enable rapid deployment
Upon arrival at the destination, the folding photovoltaic container can be put into use quickly. Compared with the traditional off-grid power station construction, there is no need to carry out cumbersome infrastructure projects, such as ground leveling, house construction, photovoltaic bracket installation, etc. Simply unfold and fold the photovoltaic panel, connect the internal electrical lines, and start generating electricity. The entire deployment process can be completed within a few hours, greatly shortening the time interval from equipment transportation to power supply, can timely meet the electricity demand in emergency situations, and provide powerful power support for rescue and disaster relief, emergency response, etc.
3. Reliable energy independence
Relying on solar power generation, folding photovoltaic containers truly achieve energy self-sufficiency. As long as there is sunlight, it can continue to generate electricity and completely get rid of the dependence on the traditional power grid. This is crucial for areas that are far from grid coverage or where grid power is unreliable. Whether it is long-term residential electricity, agricultural irrigation electricity, or short-term temporary activity electricity, it can rely on its own power generation capacity to provide stable and reliable power guarantee to ensure the normal progress of production and life activities.

Third, folding photovoltaic container transportation points for attention
In the transportation process of folding photovoltaic containers, special attention needs to be paid to the following key points.
1. Fixed and protective measures
The container is tightly fixed to the compartment using professional lashing straps, chains and fastening buckles to prevent the container from displacing, slipping or even tipping due to the operation of the vehicle such as bumping, braking and acceleration during transportation. At the same time, for the corners of the container, doors and Windows and other vulnerable parts, appropriate protective measures should be taken, such as the installation of anti-collision corners, packaging anti-collision foam, etc., to avoid damage to the internal electrical equipment and photovoltaic panels caused by collisions during transportation.
2, Moisture-proof and waterproof treatment
Although the folding photovoltaic container itself has a certain waterproof performance, special attention should be paid to moisture-proof and waterproof during transportation. Especially when transported by water or in rainy weather, check whether the sealing strip is intact. For internal electrical equipment and battery packs, if necessary, additional moisture-proof measures can be taken to prevent moisture from affecting the performance and service life of the equipment.
3. Shock absorption and buffer measures
In order to reduce the impact of vibration on the internal equipment during transportation, it is necessary to set up appropriate shock absorption and buffer devices between the container and the transport vehicle as well as between the equipment inside the container and the box. For example, installing shock pads at the bottom of containers, adding rubber shock absorbers to the fixed brackets of internal equipment, etc., can effectively absorb and disperse vibration energy, protect precision equipment such as photovoltaic panels, inverters, and battery packs from vibration damage, and ensure that they can still operate normally after transportation.
4. Transportation route planning and monitoring
Before transportation, it is necessary to carry out detailed planning of the transportation route, try to choose a good road condition, flat and stable road, to avoid rugged mountain roads, potholes and areas with serious traffic congestion. At the same time, during the transportation process, it is necessary to conduct real-time monitoring of the transportation vehicle through the satellite positioning system, vehicle sensors and other technical means, and timely grasp the vehicle’s driving position, speed, vibration and other information, so that measures can be taken in time to adjust and deal with abnormal situations.

Fourth, the use of folding photovoltaic containers to save the construction time of off-grid power stations
Compared with the traditional off-grid power station construction method, folding photovoltaic containers can significantly save construction time and greatly improve the timeliness and efficiency of power supply.
The construction of traditional off-grid power stations usually requires on-site foundation construction, including site leveling, digging foundation pits, pouring concrete foundation, etc. These basic projects often require a lot of time and manpower and material resources, and are greatly affected by weather conditions. After the completion of the foundation construction, it is also necessary to carry out a series of complex work such as the installation of photovoltaic brackets, assembly and fixing of photovoltaic panels, laying and connecting of electrical lines, installation and debugging of inverters and battery packs, and the whole construction process may take weeks or even months.
The use of folding photovoltaic containers, after transport to the site, only need to carry out a simple expansion and connection operation to complete the construction of the power station.
As mentioned earlier, the work of unfolding photovoltaic panels, connecting internal electrical lines, etc., can usually be done in a matter of hours, and even with the addition of transportation time, the total time from project start-up to power supply can be significantly reduced. According to the actual project experience, the construction of off-grid power stations using folding photovoltaic containers can save more than 80% of the construction time compared to the traditional construction method, which has unparalleled advantages for those emergency situations or time-sensitive projects that urgently need power supply.
