On the illustration from storage-lab, we can verify which technologies are being used in each system size as shown below. We can clearly see that lead-acid batteries are dominant in all sectors due to technological maturity, wider usage, and low prices. Soon though, lithium-ion batteries will catch up and replace lead-acid batteries.

You can find more information on our web, so please take a look.

A short comparison of the advantages and disadvantages of different types of batteries helps indicate when each technology can be used at its best. 

• • • • Lead-acid batteries: traditionally used as starter batteries and stationary energy storage systems due to their low cost and relatively good performance. However, the short lifetime of the batteries requires frequent maintenance and replacement, which can create difficulties. Good manufacturers of Lead-acid batteries include: Hoppecke, Victron, Newmax
      • Lithium Nickel Manganese Cobalt Oxide (NMC): used in Electric Vehicles due to their high specific energy. Now at a lower price, many manufacturers have started to produce energy storage systems with NMC technology such as SolarEdge Kokam, Tesla, LGchem, Samsung SDI…

Lithium Iron Phosphate (LPF): used for energy storage due to their safety and lower cost than NMC by manufacturers such as BYD, Pylontech, Solax Triplepower,  Sonnen…

Safety First: As always, safety for installers, their clients and the system are the priorities. 

With competitive price and timely delivery, CHANGINGTECH sincerely hope to be your supplier and partner.

• • • • Installers should always follow the safety instructions of inverter and battery manufacturers. 
      • The ESS must be closely monitored on-site and remotely by professionals. 
      • Installers should perform periodic inspections of the system yearly
      • In the case of some issues with the system, they should be fixed immediately. 

Transportation: Batteries and especially Lithium-ion batteries may be listed as hazardous goods that require special transportation methods. Installers should check carefully with distributors or manufacturers about these conditions in advance. Read more.

Care about the end of life process: Batteries generally have a shorter lifetime than other components of the system, which means that the installer must find out what to do with them after decommissioning. Chemical-based batteries may contain hazardous or toxic substances. Work with manufacturers to get instructions on how to dispose of batteries safely. 

Commercial vs. Residential Energy Storage Systems: What’s the Difference?

Commercial energy storage systems (ESS) and residential energy storage systems are similar in many ways, but there are some key differences that set them apart. Here’s a comparison of commercial vs. residential ESS:

1. Size and Capacity: Commercial ESS are typically larger in size and have a higher capacity than residential ESS. Commercial ESS is designed to carry a significant amount of load, while a residential ESS is primarily for home use.
2. Energy Needs: Commercial ESS usually have a much higher energy demand than residential ESS, which are often designed to support the energy needs of a single household. Commercial ESS are often used to power entire buildings, facilities, or industrial operations.
3. Cost: Commercial ESS is generally more expensive than residential ESS since they require more energy storage capacity and larger-scale components. However, the initial costs can be cheaper for commercial ESS since they are ideal for supporting renewable energy and reducing overall energy costs.
4. Accessibility: Commercial ESS usually require professional installation, while residential ESS can be installed by homeowners.
5. Modular Design: Commercial ESS may be designed to be modular, where units can be added as power requirements increase, but having multiple residential ESS units is often impractical even if it’s possible.
6. Safety Standards: Commercial ESS are subject to higher safety standards, which are necessary due to their larger size and capacity. Residential ESS, on the other hand, are not used for large-scale commercial or industrial activities and have less stringent safety and performance requirements.

Overall, while residential and commercial ESS share similarities in their core functionality, the key differences lie in their capacity, energy output, and access to professional installation and safety standards. As such, the type of ESS required is dependent on the specific needs of the users and the scale of the energy storage requirements.
