Orison employs an innovative technical approach to ensure that electricity never flows beyond the meter and back onto the grid. During grid disruption or a power outage, Orison uses a combination of software and fast acting hardware to sense the grid disruption and immediately stop injecting electricity into the home. Any appliance that is directly connected to Orison will remain powered. During extended blackouts, you can manually open the breaker of the branch circuit it is connected to. Once Orison confirms it is islanded from the grid, it will resume providing high-quality AC electricity to the loads on those circuits. Remote self-islanding is possible by installing the optional AFCI breaker.
