Quick Answer
Yes, it is possible to legally disconnect from the grid, but the process and regulations vary by country and jurisdiction.
Understand Your Jurisdiction
Before disconnecting, familiarize yourself with local regulations and utility company requirements. In the United States, for example, the National Electric Code (NEC) dictates that any grid-tied system must meet specific safety standards. You may need to obtain a permit or meet certain electrical inspection requirements.
Choosing the Right Equipment
To disconnect safely, you’ll need to select equipment that meets or exceeds NEC standards. This includes installing a main disconnect switch, a ground fault circuit interrupter (GFCI) for each 15-ampere branch circuit, and a lockable disconnect switch for your solar inverter. Consider hiring a licensed electrician to ensure compliance.
Notifying Your Utility Company
Once you’ve installed your off-grid system and disconnected from the grid, notify your utility company of the change. This may involve filing a form or obtaining a certificate of disconnection. Be prepared to provide proof of system inspection and compliance with local regulations. In some cases, you may need to pay a disconnection fee.
