SPAN is compatible with any grid-tied inverter for solar-only systems, and integrated with the following battery storage systems, depending on the panel type: Tesla, SolarEdge, FranklinWH, Enphase. Learn more about battery compatibility here: Storage System Integrations with SPAN.
Once installed and properly configured, your battery storage system will pass data to SPAN so you can see that information reflected in the SPAN Home App. While this data should align well with the data reflected in the battery storage system's app (Tesla App, mySolarEdge, FranklinWH App, Enlighten), there are times when there may be some discrepancies.
Understanding Data on the Flow & Home Screens
While the SPAN Home App will look slightly different depending on the SPAN Panel you have, the information about your solar and battery data will be the same.
Homeowners with a SPAN Panel Main 32 will be able to see their power usage in a handy graphic on the Flows page of their app while homeowners with a SPAN Panel MAIN 16, SPAN Panel MLO 24, SPAN Panel MAIN 40, or SPAN Panel MLO 48 will find this on the Home page of their app. In either case, these screens will show:
- 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.
If the solar and battery icons are grayed out for SPAN Panel Main 32 or if the solar and battery icons are missing from SPAN Panel MAIN 16, SPAN Panel MLO 24, SPAN Panel MAIN 40, or SPAN Panel MLO 48, this means that hardware has NOT been added (you'll just see the main consumption bubble in the middle of the screen).
You can follow instructions here to see if Support can help get this hardware added: Adding Circuit Breakers, Solar, Batteries to Your SPAN Panel.

Solar Production Looks like Home Consumption in the SPAN Home App
If the solar inverter breaker is in SPAN, but was added to the Panel as a regular branch breaker, solar electricity production will appear as home consumption in the SPAN Home app.
A SPAN Authorized installer or the SPAN Support team can update the commissioning to address this. See Adding solar to your SPAN Panel and Why doesn't my Home app show solar production data?
Total Home Consumption in the SPAN Home App is Greater than the Sum of the Individual Circuits
The SPAN Panel itself monitors only the circuits in the SPAN, and not upstream or downstream loads.
For this reason, the data for individual SPAN circuits may add up to a slightly different number than what's displayed for total home consumption.
If you have solar and batteries, there could be a load upstream of SPAN (such as a subpanel or EV charger) that is powered by the storage equipment and contributes to the total home consumption.
If there is an upstream load that has not been configured in the SPAN Installer App, the home consumption will not reflect that load.
Your SPAN installer or SPAN Support can update the system to account for loads upstream of SPAN.
Total Home Consumption in the SPAN Home App is 0
If your home is using less that 50w of power, the home screen of the SPAN Home App will show 0 total consumption (as pictured below). This applies to homeowners with one of the following panels: SPAN Panel MAIN 16, SPAN Panel MLO 24, SPAN Panel MAIN 40, or SPAN Panel MLO 48.

Solar Production Doesn’t Match in SPAN or Solar App
- For SolarEdge systems, it's best to check the SolarEdge web dashboard in addition to the mySolarEdge app.
-
For Tesla systems, SPAN gets the solar data from the Tesla Gateway. It's possible the current transformers (CTs) were not wired properly in the Tesla Gateway. For example, if SPAN is reporting half or double the solar production Tesla reports, that's a good indicator that the current transformers are facing the wrong direction.
Please contact Tesla Support or your Tesla installer to verify the CTs are installed correctly. SPAN Support won't be able to verify this on our end but Tesla Support or your Tesla Installer should be able to verify if the CTs were installed correctly.
Solar Production Showing in the Enphase App but not the SPAN Home App
SPAN's Remote Meter Kit is required to enable compatibility with Enphase systems. The Remote Meter Kit is wired into the Enphase system to measure voltage and current at various points in order to capture grid state, solar production, battery power, and home loads. This data is transmitted to the SPAN Panel through current transformers (CTs) and a single communications cable.
If you see a solar reading of 0W in the SPAN Home app, for example, it’s possible that the current transformers (CTs) were installed backwards. SPAN would see negative solar production and present a solar reading of 0W. SPAN Support can help identify miswiring of the CTs, however, the wiring may need to be confirmed and corrected by the installer.
Troubleshooting Guidance
If you have Permission to Operate and have confirmed with your installer that the solar and battery hardware have been connected to SPAN, but still see inaccurate solar and battery data, please contact SPAN Support with the following information:
-
Required Information:
- SPAN serial number
- Screenshots from both the SPAN Home App and solar/battery app taken at the same time for comparison purposes. Please note for SolarEdge issues, it's best to take a screenshot of the web dashboard.
- Confirm the solar and battery breaker locations (in SPAN, or upstream of SPAN such as in a Tesla Gateway or SolarEdge Backup Interface)
- SPAN Support can gather more information by adding Support to your Home App account. Please indicate whether you grant permission for Support to view your Home app remotely.
- More Information that can help SPAN Support troubleshoot:
- When did you notice this issue?
- Does it seem to happen at a particular time of day consistently?
- Do you have a plan set from the solar/battery installer?
- A single-line diagram can be very helpful in understanding the whole system.
- Does your solar/battery system have Permission to Operate (PTO) at this time, or are you waiting on approval from the utility?
-
Have you made any changes to your SPAN circuits or solar/battery hardware recently?
Are there any appliances powered by circuits that are not in the SPAN Panel but are supported by the battery system, such as an EV charger, another electrical panel or subpanel?
