Enphase Q-Relay-1P-INT (1-phase)
The Q-Relay provides external grid protection for the Enphase micro-inverters. During specified grid disturbances, the Q-Relay disconnects the Enphase microinverters from the AC grid. Once the voltages or line frequencies are back within acceptable limits, the Q-relay will reconnect the system to the grid.
You only need one Q-Relay per connection. A maximum of 16 IQ7+ can be operated on one Q relay.
The Q-Relay must be housed in a weatherproof DIN rail enclosure.
