Are solar batteries safe?
Solar battery technologies and their risks
Lead Acid Batteries
Lithium Ion Batteries
However, lithium ion batteries are safe as long as they are installed properly. The battery management solution monitors the temperature, voltage, and power to ensure safety. These batteries are also designed with proper thermal materials to dissipate heat and enable them to handle higher currents and voltages. These batteries can also come with redundancies and safety measures built into them. However, due to their complexity, lithium ion batteries are hard to recycle and dispose of at the end of their life cycle.
Salt Water Batteries
Solar battery safety standards
- UL 9540 – Standard for Safety of Energy Storage Systems and Equipment
- UL 9540A – Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems
- NFPA 855 – Standard for the Installation of Stationary Energy Storage Systems
- IEC 61427-1
- IEC 61427-2
Here in the United States many of the equipment used must have those safety codes. OSHA, The U.S. Department of Labor’s Occupational Safety & Health Administration, operates a Nationally Recognized Testing Laboratory (NRTL) program which also includes UL. There are about 20 organizations that are currently listed as NRTLs, and these NRTLs have a website that you can visit to check a product’s safety standard. Any fraudulent products using an NRTL are penalized harshly, making them rare and ensuring that properly marked products are safe.
You can be sure knowing that your solar batteries are safe to be installed and used in your home. With the multiple safety standards set and the professional installation and maintenance done, you can enjoy the benefits of your solar storage without any worries.
