Note: The Sense Home Energy Monitor should be installed by an electrician or qualified professional, and should be installed in compliance with all applicable local codes.
The Sense Home Energy Monitor is compatible with most split-phase 120/240V OR 400A split-service residential electrical panels in North America. Individual panels up to 200A are compatible. Your panel must have enough space to fit sensor clamps with HxWxD dimensions of 3.375" x 2" x .75" (85.73 x 50.8 x 19.05mm), and an inside diameter of 1”. Our sensor cables are 46" (116.84cm) long and our power cable is 36" (91.44cm) long. Sensor cable extensions are available in lengths of 4', 12', 25', and 40' to help facilitate different types of installations.
Sense can work with split-service systems up to 400A where service is provided via dual panels. Data from both panels will be summed in the Sense app. This feature requires use of the monitor’s auxiliary port and thus this port cannot be in use by solar monitoring or another feature.
Sense can monitor subpanels, provided that the monitor is installed in the main panel and the subpanels are downstream of this panel.
Busbar panels must have enough clearance for the current sensors to clamp around the busbar. Please see above dimensions.
Recessed or flush-mounted panels
Sense is compatible with recessed panels. You can read more about the installation process here.
Sense is designed to monitor traditional homes in North America with split-phase 240V service, but it can also successfully monitor two out of the three legs of three-phase 208V service. It is important that Sense is powered by a two-pole breaker across the two legs that will be monitored, and that the current sensors are clamped around the service mains for the same two legs. The power consumption of any devices on the third leg will not be monitored, but the monitoring capabilities of Sense will be fully operational on the other two legs.
At this time, Sense does not support a parallel feed configuration. We are working on a solution to better accommodate this configuration and hope to have it available in the near future.
To install Sense outdoors, it must be enclosed inside an appropriate NEMA-rated enclosure, and adequately protected from the elements. Sense is compatible only in the following environmental conditions:
Relative humidity <90%; IPX0 rating, no water ingress
Temperature: 32-154ºF (0-68ºC)
Elevation < 6562' (2,000m)
