Solar data display in the Home App
The SPAN Home App displays solar production data when a solar system is successfully added to the SPAN configuration by an authorized SPAN installer or SPAN Support.
When a solar system is added, the yellow sun icon in the Home app will turn from gray to yellow and show live solar production values. Solar information will also be tracked in the Home App.
The SPAN Home App Flow screen illustrates the direction power is flowing in your home.
- Solar line flowing from the solar icon to the Panel indicates solar is being produced.
- Grid flow direction indicates if the Panel is sending power to the grid or receiving power from the grid.
- Battery flow indicates if the battery is being charged or if SPAN is receiving power from the battery
Adding Solar to your SPAN configuration
Your SPAN configuration will need to be updated to include the solar inverter information.
Full instructions & required information can be found here: Adding Solar (without battery backup).
Solar Data & Monitoring
SPAN can monitor your home’s solar production in the following ways only:
- With built-in relay measurements in the SPAN Panel on circuits 21-32. Solar production must land on a dedicated circuit in one of these slots only.
- Through integration with a SolarEdge Energy Hub or Tesla storage system. Solar production would be upstream of SPAN in this scenario, landed in either SolarEdge’s BackUp Interface or Tesla’s Gateway or Tesla’s Powerwall+. The storage system monitors solar production and reports the values to SPAN for Home App display.
- Using SPAN Remote Meter Kit CTs when SPAN is installed with an Enphase storage system. In this scenario, solar production also lands upstream of SPAN, inside Enphase’s Site Controller. Solar production is monitored by SPAN, not Enphase.
Please note: While SPAN Remote Meter Kit is able to monitor solar production, it is only intended for use when installed with an Enphase storage system. Upstream (of SPAN) solar-only monitoring through SPAN Remote Meter Kit is not supported today.

Solar Data will not display when
- Solar breakers are landed in the incorrect slots in SPAN.
- Solar breakers can be landed in slots 21-32 only. If solar is landed in a traditional subpanel fed by SPAN or another electrical panel outside of SPAN, the solar data cannot appear in the SPAN Home App.
- Solar breakers are landed in a non-compatible battery system
- Solar breakers are installed upstream of SPAN in an unmonitored configuration, such as a line-side tap or supply-side connection
- The system is awaiting permission to operate and is not currently producing.
- The solar system has not been added to the SPAN configuration by a SPAN-authorized installer or SPAN Support yet.
- The solar breaker was labeled as a regular branch breaker instead of added to your SPAN configuration as solar hardware.
- Contact SPAN Support with the instructions below for assistance.
Please note: SPAN does not require any additional CTs or monitoring for solar when the solar breakers are landed in the approved slots in SPAN. When installed with a compatible storage system, SPAN receives battery and solar information from the storage system.
Confirm the solar breaker location:
- If solar breakers are landed in SPAN: Confirm solar breakers are landed in the correct SPAN slots: 21-32.
- If solar breakers are not landed in SPAN: Confirm the storage system is compatible with SPAN. See our FAQ for full information about compatibility: Storage System Integrations with SPAN
- For SPAN with Enphase and Remote Meter Kit: Ask your installer to confirm CTs are installed correctly if solar breakers are not landed in SPAN.
Compare SPAN Home App to your solar app
- Solar information should be the same in both Apps.
- If your solar app displays no solar production: please contact to your solar installer for support with the solar system
- When paired with a compatible battery storage system, SPAN receives information from the storage system for solar, battery, and grid status. This means the solar information in SPAN and Tesla or SolarEdge app should match.
- Differences in solar values may be caused by the reasons listed above, or installation errors such as missing or backwards CT.
If you have exhausted the above steps for troubleshooting, have confirmed with your installer that solar is landed in the correct locations, and you have PTO, please contact Support with the following information:
