This switch acts as the rapid shutdown initiator for grid-forming IQ8 Series Microinverters.īackup-capable systems with IQ8 Series Microinverters require IQ Gateway (formerly known as IQ Envoy) software version 7.3.120 or later. The System Shutdown Switch along with 20 feet each of red, black, orange and purple wires are included in the IQ System Controller 2 package. Sunlight Backup systems require the use of the System Shutdown Switch. You must install at least one IQ Load Controller before commissioning a Sunlight Backup system. Sunlight Backup systems support up to 4 x 240 V or 8 x 120 V essential load circuits with two IQ Load Controllers and 2 x 240 V or 4 x 120 V essential load circuits with one IQ Load Controller. IQ System Controller (formerly Enpower) is incompatible with Sunlight Backup systems. Sunlight Backup systems require the use of an IQ System Controller 2. Hold-down kits are required for all solar PV branch circuit breakers in IQ Combiner 4/4C and IQ Combiner breaker in IQ System Controller 2. This applies for all system configurations, with and without storage.

Systems with IQ8 Series Microinverters must contain only IQ8 Series Microinverters as they are incompatible with older generations of Enphase IQ Microinverters, including IQ6 and IQ7 Series Microinverters.
