Megapack units will have an active thermal management system comprising of liquid cooling system installed within each enclosure providing thermal management to internal components to limit heat diffusion as described in the Fisher Engineering Report, 2035-03R22035-04R, Page 6 - 7.
Product
Megapack units will have system shutdown/disconnect with multiple levels of passive and active electrical protections, including battery module overcurrent protection via fusible links on the DC side of the modules, inverter DC and AC protections, and ground fault detection as described in the Fisher Engineering Report, 2035-03R22035-04R, Page 11.
Product
Megapack units will have passive circuit protection and design with fused disconnects and DC disconnect switches, in addition to ground fault detection/interruption and over voltage protection as described in the Fisher Engineering Report, 2035-03R22035-04R, Page 10 - 11.
Product
If the Megapack BESS units operate out of normal voltage parameters, the BMS will trigger fault and alarm monitoring indicators and initiate the protection system to disconnect as described in the Fisher Engineering Report, 2035-03R22035-04R, Page 10.
Product
Inverter modules will be equipped with both DC protection via high-speed fusing for passive or active isolation or battery module, as well as dedicated AC contactor and AC fuses will an abnormal electrical event occur at the inverter modules on the AC side of the circuit as described in the Fisher Engineering Report, 2035-03R22035-04R, Page 10 - 11.

Project
Tesla have undertaken additional internal destructive fire testing, beyond that required by the UL 9540A test and fire modelling, to help understand the risk of fire propagation to adjacent BESS units. The additional testing and fire modelling concluded that, in the unlikely event of a fire, it would not propagate from one Megapack unit to an adjacent unit installed at minimum clearances as per the Tesla Megapack 2/XL Design and Installation Manual.
Project
Vegetation buffer zones will be included, with a minimum of 10 m clearance between the Megapacks and the fence line. The entire fenced area will be gravel and void of vegetation. This will allow for access by the NSW RFS fire tender in accordance with the NSW RFS request.
