Otherwise the system will work on island mode and remain unsafe for you to work on.
Rapid shutdown solar panels long island.
The rapid shutdown rule now in force in most jurisdictions means that micro inverters or power optimizers need to be used rather than string inverters.
But to use other hardware whether it be a string inverter a charge controller or a hybrid inverter requires additional electronics to accomplish the shut down tigo appears to be the primary supplier of relevant hardware they have 2 very different.
Requirements for controlled conductors shall only apply to pv system conductors of more than 5 ft inside a building or 10 ft from a pv array.
The section 690 12 update to the 2017 national electrical code nec calls for module level rapid shutdown of solar systems instead of nec 2014 s array level shutdown requirement.
