Energy storage systems (ESS) are rechargeable batteries that can store energy from different sources, like renewable sources, the grid, or generators, and then release it when the power is needed. It consists of one or more batteries and can be used to balance the electric grid, provide backup power and improve grid stability. The stored energy can be used for self-consumption, reduce electricity bills, and be sold to the grid for profits. As the next phase of the Paris Agreement rapidly approaches, governments and organizations around the world are looking to increase the use of renewable energy. Some of the regions with the largest energy users have additional incentives to find alternatives to traditional energy sources. These developments are driving the market for battery energy storage systems. Lithium ion ESS products are green, pollution-free, and environmentally friendly,flexible installation, modularization, rapid response, and short construction cycles will make it integral to applications such as peak shaving, self-consumption optimization, and backup power in the event of outages. They are widely used in places with insufficient power such as homes, businesses and industries to solve the problem of power shortage.
Renewable energy is considered to be the best new energy in the 21st century. The use of solar power to generate electricity is very clean, with high safety, relative wideness and adequacy of energy, long life, maintenance-free and other advantages that other conventional energy sources do not have. Solar street light does not need to lay cables, AC power supply, and no electricity bills. It adopts DC power supply and control. Because of good long life, high luminous efficiency, energy saving, easy installation and maintenance and environmental protection, it can be widely used in urban main and secondary arterial roads, communities, factories, tourist attractions, parking lots and other places.
Our solar lighting battery has low voltage charging design. When the battery is seriously run out, the 0V charging problem of the battery is solved through a dedicated low-voltage charging circuit. The high consistency of the batteries and the BMS intelligent balance management system effectively improve the efficiency of the batteries, with a calendar life of more than 8 years. It can work well in wide temperature range with a controller system and energy-saving regulation.
With the increasing growth of global power demand the security of the power grid becomes more and more important.Power failure or shortage will have a negative impact on any economy. Battery energy storage system is considered an effective solution to make any grid more reliable and more flexible. They are widely used in places with insufficient power such as homes, businesses and industries to solve the problem of power shortage. By charging at off peak loads and discharging at peak loads ESS provides peak cut/shift and reliable and fast frequency response to the grid. When the grid fails, as an emergency power supply ESS can ensure normal power supply. Not only can it be used for self-consumption, reducing electricity bills, but also sold to the grid for profits. ESS balances the load demand and relieves the impact of peak load on the power grid, reduces the investment cost of upgrading the power grid and the energy loss during transmission and distribution. The overal operation efficiency of electricity equipments is improved.
With the continuous development of the internet today people are paying more attention to big data platforms. The internet data center provides large-scale, high-quality, safe and reliable server hosting for major websites and the uninterruptible power supply (UPS) system provides reliable data protection for the data center and solves monitoring, maintenance, service power supply issues. It is also suitable for emergency power supply of various electrical equipment when power failure. When AC power is supplied, it is the function of a voltage stabilizer and a filter to eliminate or weaken the interference of AC power and ensure the normal operation of the equipment. When the AC power is interrupted, it can convert the DC power provided by its DC power supply into perfect AC power for the load. The switch from AC power to battery power is generally 0 time switch so that the load equipment can keep running without any changes, which truly guarantees the equipment’s performance.
Battery energy storage has a key part to play in ensuring homes and businesses can be powered by green energy, even when the sun isn’t shining or the wind has stopped blowing. The need for innovative energy storage becomes vitally important as we move from fossil fuels to renewable energy sources such as wind and solar, which are intermittent by nature. BESS compensates for the shortcomings of intermittent and instability of solar power and wind power. It stores energy generated irregularly and intermittently by solar/wind power generation systems. Through charging and discharging methods, it quickly responds to frequency-regulated and voltage adjustment commands, stabilizes renewable energy output, minimizes output fluctuation, improves power quality, deals with grid stability problems caused by large-scale renewable energy grid connection, improves grid stability and ultimately enables a more efficient, reliable, and sustainable electricity grid.
Based on the principle of photovoltaic effect, solar energy is converted into electric energy and stored in the battery pack for use in equipment. It is characterized no pollution, no noise, low maintenance cost, high energy density, and long service life. It's always used in remote mountainous area, no power area, island, communication base station and street lamp etc. Specially aimed at areas without power grid or frequent power failure, as well as places with large peak-to-valley price differences or frequent power outages such as factories and businesses. It is divided into grid-connected and off-grid systems, and can be used in the "use while storage" or "storage before use" mode to solve the problem of power shortage.
The residential energy storage system is mainly applied in family energy storage of solar power generation, especially areas of lack of power, little power, or unstable grid. The electricity generated by solar is supplied to the household load, and its operation is not affected by the pressure of the power supply of the city.
During the low power consumption period, the battery pack in the household energy storage system can be self-charged to be used in the case of standby power peaks or power outages. In addition to being used as an emergency power source, it can also save household electricity costs because they can balance the electrical load.
