Danger to life due to incompatible lithium-ion battery
An incompatible lithium-ion battery can lead to a fire or an explosion. Use of incompatible
lithium-ion batteries can also make the user’s battery management system unsafe, and void
manufacturers’ warranties. To avoid fire or explosion, we strongly recommend doing the following:
• Verify that the battery complies with locally applicable standards and directives, and is
intrinsically safe.
• Verify that the particular lithium-ion battery type is approved for use with the SMA Sunny
Island inverter (please see “List of Approved Lithium-Ion Batteries” under the Technical
Information tab at www.SMA-America.com).
• If manufacturer approved Sunny Island lithium-ion batteries are not available, you may use
lead acid batteries.
