What happens when the optimizer fails and you need the shut-off/circuit protection shut-off?

Please see Tigo Energy’s whitepaper on PV-Safe for a complete description.  The code requires that the controlled conductors must be lower than 30V 10-feet from the array within 10 seconds of activation.  Should one of the Tigo units fail the voltage of a single module will not cause the controlled conductors to exceed 30V
