Megapack is designed with features that make the product safe throughout the entire product lifecycle — during transit, installation, commissioning, operation, maintenance, and decommissioning. Tesla’s approach to safety involves comprehensive design and testing at every level of Megapack. Vertical integration across design, manufacturing, and testing ensures that safety features of the cell, battery module, inverter, thermal system, and overall system-level components are closely linked and not decoupled. 1. Individually fused battery modules (active and passive) – externally serviceable 2. Touch-safe Customer Interface Bay 3. Externally serviceable inverter bay 4. Non-walk-in IP66 enclosure, with internal and external thermal insulation and deflagration mitigation 5. Thermal roof with overpressure vents INDUSTRY-LEADING COMPLIANCE AND THIRD-PARTY VALIDATION Tesla is constantly pushing the boundaries and raising the bar on product safety. This commitment to safety not only ensures that Tesla’s products are compliant to the industry’s most stringent global standards, but also sets a benchmark for the industry to follow regarding energy storage safety. Megapack has met and exceeded many industry safety standards and has demonstrated through extensive third-party testing that it is one of the safest energy storage systems on the market. Megapack is tested and listed to the following standards by OSHA-recognized Nationally Recognized Testing Laboratories: • UL 1642 (cell-level certification) • UL 1973 and IEC 62619 (battery module-level certification) 1
