Maintenance and Safety Considerations for Home Energy Storage Systems
Article from | Franklin Whole Home
Home energy storage systems, also known as home battery systems, have become increasingly popular in recent years as a means of storing excess energy generated by renewable sources such as solar panels. As part of a whole home energy management solution, these systems allow homeowners to save energy generated from solar, the grid, and generators, for use during periods of high demand, such as in the evening, when electricity from the grid is more expensive. In addition, these systems can provide backup power during power outages.
While home energy storage systems offer many benefits, it is important to consider maintenance and safety considerations when using them. Proper maintenance and safety precautions can help ensure that the system operates smoothly, efficiently, and safely.
Maintenance Considerations
Battery Management System (BMS): The battery management system (BMS) is a critical component of home energy storage. The BMS ensures that the battery is charged and discharged within safe limits, prevents overcharging or undercharging, and monitors the battery's temperature, voltage, and current. The BMS is usually monitored by the energy management system (EMS), as in the Franklin Home Power solution, to ensure that it is working properly and that the batteries are not being damaged.
Battery Replacement: A home energy storage system’s lifespan can vary depending on the type of battery and the frequency and magnitude of use. Regular monitoring of the battery's state of health, and replacement when necessary, is important to ensure that the system continues to perform at its best.
Cooling System: Most home energy storage systems have a cooling system that helps regulate the temperature of the battery. Regular cleaning of the cooling system and checking its operation is important to ensure that the battery is not overheating and that the system is operating efficiently.
Software Updates: Software updates are necessary to ensure that the home energy storage system continues to operate optimally and to address any security or performance issues. It is important to keep the system updated to ensure that it continues to perform at its best. Over-the-air (OTA) updates are optimal because they quickly provide the latest technology and remove the need for a technician to travel to every installation.
Safety Considerations
Electrical Safety: Home energy storage systems use high-voltage batteries, which can pose a hazard if not properly handled. It is important to ensure that the system is installed and connected by a qualified electrician and that the electrical connections are properly made and maintained.
Fire Safety: Older lithium-ion batteries, which are used in some home energy storage systems, have a risk of thermal runaway and fire. Regular monitoring of the battery's temperature, voltage, and current, as well as ensuring that the system is installed and connected properly, can help reduce the risk of fire. Modern technologies, such as lithium-iron-phosphate (LFP), are much safer and remove almost all fire risks.
Battery Disposal: Home energy storage system batteries must be disposed of properly to avoid environmental hazards. Batteries should never be thrown in the trash, as they contain toxic chemicals that can harm the environment.
Carbon Monoxide: Some home energy storage systems use internal combustion engines, such as gasoline-powered generators, to charge the battery. These systems can produce carbon monoxide, a colorless and odorless gas that is toxic to humans. It is important to ensure that the system is installed in a well-ventilated area to reduce the risk of carbon monoxide exposure.
Monitoring
Safety is enforced by monitoring. Both installers and homeowners should be able to see the condition of the system and be notified of any conditions that require action. Two key methods are used to monitor home energy management and battery storage systems. First is simple access through a mobile phone app. Both homeowners and installers can see the basics of system operations and be instantly alerted to changing conditions. The second is the web. Today’s systems use the cloud to provide installers with more detailed information, allowing analytics providing predictive maintenance and other tools to ensure their customer systems are running optimally and safely.
Conclusion
Home energy storage systems offer many benefits, but it is important to consider both maintenance and safety considerations when using these systems. Regular monitoring of the system and its components, proper installation and connection by a qualified electrician, and regular software updates can help ensure that the system operates smoothly, efficiently, and safely. Regular monitoring of the battery's state of health, and proper disposal of batteries, when necessary, can also help ensure that the system continues to perform at its best. By taking these considerations into account, homeowners can enjoy the many benefits of a home.
