According to NFPA 855, individual energy storage system units should generally be separated by at least three feet, unless the manufacturer has conducted large-scale fire testing (part of UL 9540A) to prove a smaller distance is safe. This prevents a fault in one unit from spreading. Adhering to established codes for battery cabinets protects your investment, ensures safety, and maximizes performance by preventing thermal issues before they start. Understanding the reasons behind these rules helps reinforce their importance. Accessibility and Maintenance Needs. Specifically, safety regulations mandate a particular spacing to.

[PDF Version]Therefore, if you install multiple storage units, you have to space them three feet apart unless the manufacturer has already done large-scale fire testing and can prove closer spacing will not cause fire to propagate between adjacent units.
In Section 15.5 of NFPA 855, we learn that individual ESS units shall be separated from each other by a minimum of three feet, unless smaller separation distances are documented to be adequate and approved by the authority having jurisdiction (AHJ) based on large-scale fire testing.
Individual ESS units shall have a maximum stored energy of 20 kWh per NFPA Section 15.7. NFPA 855 clearly tells us each unit can be up to 20 kWh, but how much overall storage can you put in your installation? That depends on where you put it and is defined in Section 15.7.1 of NFPA 855.
You can have up to 40 kWh within a storage or utility space inside the home. For an attached or detached garage or a detached accessory structure, you can go up to 80 kWh. Outdoor installations, including those on exterior walls, can go up to 80 kWh. See the illustration below for a visual example of these capacity restrictions.
