Enphase Q-Relay-1P-INT (Single-Phase)
The Q-Relay serves as an external grid and system protection device for the Enphase microinverters. During specified grid disturbances, the Q-Relay disconnects the Enphase microinverters from the AC grid. As soon as the voltage and grid frequency are back within the acceptable range, the Q-Relay restores the system's grid connection.
You only need one Q-Relay per connection. Up to 16 IQ7+ microinverters can be operated on one Q-Relay.
The Q-Relay must be housed in a weatherproof DIN-rail enclosure.
