The Ultimate Guide to Commercial Battery Systems: Everything You Need to Know

Over the last few decades, the prices for solar panels and wind farms have been reduced. Recently I have installed solar panels on my rooftop and I must say the solar battery system is one of the most important things as it allows you to store energy. This stored energy enables you to use it when the sun is not shining or on cloudy days. To contribute to sustainable energy, we must switch to renewable energy for a better future. 

According to a report by Grand View Research, the US battery energy storage system market size was valued at USD 336.6 million in 2019, and is expected to grow at a compound annual growth rate (CAGR) of 23.9% from 2020 to 2027. This data shows that there is a huge demand for renewable sources of energy. However, you should keep in mind that the growth of commercial battery systems is determined by various aspects including increasing adoption of renewable energy sources, government incentives, and battery costs.  In this article, we are going to learn about commercial energy storage systems

Explanation of commercial battery systems

Commercial battery systems are used to store energy generated from renewable sources like solar and wind so that it can be used when there is no sunshine or wind blowing. A typical Commercial battery systems consists of multiple battery modules connected in parallel or in series to achieve the desired voltage and capacity. The battery modules can be made up of lithium-ion batteries and their capacity can range from a few kilowatt-hours (kWh) to several megawatt-hours (MWh).

Importance of commercial battery systems

  • Battery systems for commercial use help you to store excess energy generated from renewable sources such as solar panels or wind turbines. Hence, businesses can reduce their dependence on the grid and lower their energy costs by using self-generated power.
  • Commercial battery systems can provide backup power when it is needed. This is important for businesses that want an undisturbed power supply to operate critical systems such as manufacturing facilities and utilities. 
  • Commercial battery systems are generally more powerful than home batteries as they are designed to be constantly under load. Hence, they have a longer life span and can be more reliable than other battery systems.
  • The use of commercial battery systems can help businesses to reduce their carbon footprint. This can also help businesses to improve their brand image.

Types of Commercial Battery Systems

types of Commercial Battery Systems
  • Lithium-ion battery systems

Lithium-Ion batteries are lightweight, durable, and have a very long life. They do not produce hazardous gasses when used. Hence, they are environmentally friendly. They are often used in electric vehicles, portable electronics, tesla’s home battery and even household appliances.

  • Lead-acid battery systems

Lead-acid battery systems are one of the most commonly used battery systems for industrial and commercial applications. They are reliable, durable, and have a low initial cost. However, they are heavy and have a shorter lifespan compared to lithium-ion batteries. They are commonly used in backup power systems, uninterruptible power supplies (UPS), and forklifts.

  • Flow battery systems

Flow battery systems are a type of rechargeable battery that uses two electrolyte solutions to store energy. They have a high energy density and can store energy for longer periods of time. They are often used in renewable energy storage systems and large-scale energy storage systems for power grids. 

Benefits of Commercial Battery Systems

  • Cost savings

By storing excess energy generated by solar power systems, businesses can reduce their utility bills. 

  • Energy independence

Commercial battery systems can also provide businesses with energy independence by allowing them to operate off-grid or reduce their reliance on the grid. This can be beneficial for businesses in remote or rural areas with limited grid infrastructure.

  • Environmental sustainability

Commercial battery systems can also help businesses reduce their carbon footprint and promote environmental sustainability. This can also help improve their corporate social responsibility (CSR) and enhance their reputation in the eyes of their customers.

Applications of Commercial Battery Systems

  • Backup power

Commercial battery systems can be used as a backup power source during power outages. In the event of a blackout, the battery system can automatically supply power to critical loads such as lighting, heating and cooling, communication systems, and other essential equipment.

  • Peak shaving

Commercial battery systems can be used to reduce peak demand charges by storing excess energy during off-peak hours and discharging it during peak demand periods. This can help businesses to save money on their electricity bills by reducing the amount of electricity they need to draw from the grid during peak hours when electricity prices are high.

  • Time-of-use optimization

Commercial battery systems can be used to optimize the use of electricity during different times of the day. By storing excess energy during low-demand periods and discharging it during high-demand periods, businesses can take advantage of time-of-use pricing structures and reduce their overall electricity costs.

  • Microgrid support

Commercial battery systems can be used to support microgrids, which are local, self-contained power systems that can operate independently from the main power grid. By integrating a battery system into a microgrid, businesses can increase the reliability and resiliency of their power supply, particularly in remote or off-grid locations.

Factors to Consider When Choosing a Commercial Battery System

  • Capacity

Capacity is the amount of energy a battery can store and provide over time. It is measured in ampere-hours (Ah) or kilowatt-hours (kWh). Choose a battery system with a capacity that matches your power requirements and usage patterns.

  • Voltage

Voltage refers to the electrical potential difference between two points in a circuit. Different commercial battery systems have different voltage ratings, so choose one that is compatible with your device or application.

  • Cycle life

This refers to the number of charge/discharge cycles a battery can withstand before it starts to degrade. A higher cycle life means a battery will last longer, so choose a battery with a cycle life that matches your needs.

  • Efficiency

Battery efficiency refers to the amount of energy that is lost during the charge/discharge process. Higher efficiency batteries will lose less energy and provide more power to your application.

  • Warranty

It is essential to choose a battery system with a reliable warranty to protect your investment. Check the time period of the warranty and what it covers, including replacement costs and labor.

  • Maintenance

Some battery systems require more maintenance than others. Consider the maintenance requirements of different battery chemistries, such as lead-acid or lithium-ion, and choose one that suits your needs and resources. This may include monitoring the state of charge, temperature, and voltage, as well as periodic inspections and cleaning.

Installation and Maintenance of Commercial Battery Systems

  • Proper installation process
  1. The location should be dry, and cool, and have enough space for the batteries, cabinets, and other equipment.
  2. The site should be level and free from any debris or obstacles. 
  3. Cabinets should be installed according to the manufacturer’s instructions. 
  4. The battery system should be connected to renewable energy sources. 
  • Maintenance tips and schedule:
  1. Batteries and cabinets should be inspected at least once a month for signs of damage, corrosion, or leaks. 
  2. Batteries and cabinets should be cleaned regularly to prevent dust and debris. 
  3. Batteries should be tested regularly to ensure they are holding a charge and performing as expected. 
  4. Any damaged or worn components, such as cables or sensors, should be replaced as soon as possible to prevent further damage to the system. 

Final Words

I have always been fascinated by the use of renewable energy. Commercial battery systems play an important role in the Industrial battery solutions. These systems have the power to revolutionize the way we use and store energy. Commercial battery systems have become popular in recent years as businesses seek ways to reduce their energy costs and reduce their carbon footprint. The use of battery storage can help us to optimize their energy usage and improve their energy efficiency.
