Relays act like a switch; they can be used to turn on and off specific circuits in your switchboard based on ideal conditions.

Redbacks Smart Hybrid series come with relays pre-installed, whereas the Redback’s Smart Inverter series can use an additional internal component called a Smart Meter to act as a relay.

In correlation with the Smart Load Control feature, the software can switch the relay on or off in relation to either your solar generation or export power. This means you can power an item, such as your electric hot water unit, using only solar power via the relays.
