What is Wall Mounted Battery?

Wall mounted lithium battery is an energy storage device that stores electrical energy through lithium-ion batteries and is installed on the wall. It can be connected to a solar photovoltaic system, a power grid or other energy sources to achieve efficient storage and utilization of electrical energy. It is one of the efficient, compact and intelligent energy storage solutions that stores solar panels or grid power in lithium-ion batteries for home and commercial applications. It can optimize energy use, improve energy efficiency, and provide backup power when the grid is out of power. This article will introduce the working principle, advantages and disadvantages, and application scenarios of wall mounted lithium batteries in detail.

Working principle

1. Charge mode
   Wall mounted lithium battery controls the charging and discharging process of lithium-ion batteries through a battery management system (BMS). When the grid electricity price is low or the solar photovoltaic system generates excess electricity, the energy storage system will store this electricity in the lithium battery.
2. Discharge mode
   When the grid electricity price is high or the demand for electricity is large, the energy storage system will release the stored electricity to provide electricity to home or commercial users. In addition, when the power grid is out of power, the energy storage system can automatically switch to the backup power mode to ensure the continuity of power consumption.
3. Intelligent management
   Energy storage systems are usually equipped with intelligent management software, which can monitor and manage the battery’s charge and discharge status, operating parameters, etc. in real time. Users can view the battery status through mobile phones or computers, set charge and discharge strategies, and realize intelligent energy management.
4. Goal
   Improve energy efficiency: optimize energy use by storing excess power and releasing it during high-demand periods.
   Enhance energy independence: provide backup power when the power grid is out of power to ensure power safety and continuity.
   Support renewable energy: work with solar photovoltaic systems to increase the utilization rate of renewable energy.

Advantages

• Energy storage batteries can efficiently store excess power, release power during peak power demand periods, and balance household power supply.
• When the power grid is out of power or power failures occur, energy storage batteries can provide emergency power supply to ensure the basic power needs of the family.
• The intelligent management system can automatically adjust the charge and discharge strategy according to the electricity price and power demand, optimize power use, and reduce electricity costs.
• Energy storage batteries can effectively utilize renewable energy, reduce dependence on fossil energy, reduce carbon emissions, and promote environmental protection and sustainable development.
• Users can remotely monitor and control the operating status of the energy storage system through mobile phone APP or computer, view power, voltage, temperature and other information in real time, and conduct intelligent management.
• It has a high cycle number and can provide higher reliability.
• It has a lower self-discharge rate and can maintain power for a longer time.
• It has excellent high temperature characteristics and can work normally at high temperatures.
• It has high energy density and long life and can provide long-lasting and stable power supply.

Disadvantages

• The battery is large and weight in size, and the size and weight impact need to be evaluated when purchasing
• The battery capacity decreases significantly in low temperature environment
• The cost is relatively high and not everyone can afford it.
• The charging efficiency is low, much lower than other batteries.
• The battery capacity decreases over time, which may cause the battery performance to deteriorate.
• It generates a lot of heat during charging and discharging, which is easy to burn or explode.

Final suggestion

If a continuous and stable power system is required, and it supplies power to a specific load and saves space, the wall mounted battery is a good choice. When purchasing, you need to consider its protection level and the temperature range of use.
