Electrical permit and solar or backup-power permit check for battery storage

City of Miami's solar permit instructions require applicants to indicate the size, type, and location when storage batteries are used and to show transfer switch details for switching equipment and methods from and to the public utility electrical system. Miami-Dade County also says electrical permits are required for electrical work, and its generator guidance requires permits when backup power equipment is connected to the building electrical system or permanently placed. Battery storage should therefore be confirmed through City of Miami's electrical, solar, building, fire, and utility review paths before installation.
