How is SPAN Panel compatible with Enphase?

  • Updated

Is my SPAN Panel compatible with Enphase batteries? 

If you have a SPAN Panel MAIN 32, the panel is compatible with the following Enphase IQ batteries: 

  • IQ 3, 3T, 10, 10T batteries with IQ System Controller 1 or 2*
  • IQ 5P batteries with IQ System Controller 3

To enable compatibility, a Remote Meter kit is required. The Remote Meter Kit is wired into the Enphase system to measure voltage and current. It then transmits the data to the SPAN Panel through a single communications cable, providing all of the data needed to offer dynamic, intelligent backup.

The unique nature of this integration means there are times when it may be useful to calibrate the battery, which you can do in the SPAN Home App. Manually calibrating the Enphase battery helps to ensure that the Panel is accurately estimating the battery state of energy (SoE).

At this time, SPAN Panel MAIN 16, SPAN Panel MLO 24, SPAN Panel MAIN 40, and SPAN Panel MLO 48 are not compatible with Enphase batteries. We are actively working on expanding battery compatibility for SPAN Panel Main 40 and MLO 48, and these panels will be compatible with Enphase in the future. If you’re ready to get a SPAN Panel and need it to be immediately compatible with Enphase, our SPAN Panel MAIN 32 will be the best fit for you.

If you're interested in getting matched with a SPAN Authorized installer, we recommend filling out our Get Started form. They'll be able to help determine the right panel for you. If you already have a SPAN Panel but are not sure which one you own, check out this article: How do I know which SPAN Panel I own?

When and why should I calibrate my Enphase battery in the SPAN Home App?

When your SPAN Panel is first connected to Enphase, you may see a banner in the SPAN Home App that says “Battery calibration in progress.” You can enter battery information manually to show the charge level without waiting.

If you notice a discrepancy in the Enphase battery charge shown in your SPAN Home App and the Enphase Enlighten App, it may be helpful to calibrate the battery to get the SPAN and Enphase apps in sync. See also What’s wrong with my data?

How do I calibrate my Enphase battery in the SPAN Home App?

To calibrate, follow the steps below in the SPAN Home App:

 

  1. Tap the battery icon on the Flow screen, or tap the banner that says “battery calibration in progress.”
     
  2. Tap “calibrate” next to the battery percentage to enter the “Calibrate SPAN” screen.
     
  3. Check that the system size is accurate in the Battery System section.
     
  4. In the Battery System Status section, enter current charge level, operating mode, and Backup reserve.
     
  5. Enter current charge level of the Enphase IQ battery. Find charge level on the Enlighten status screen next to your battery icon.
     
  6. Enter Operating mode, known as Profile in Enlighten (ie Savings mode, Self-consumption, or Full Backup)
     
  7. Enter Backup reserve percentage (called Reserve in Enlighten). Access it using the gear icon next to Profile on the Enlighten Status screen.

SPAN and Enphase state of energy value drifts apart even after I calibrate! 

It is possible for the battery charge estimates to drift from the actual SoE. While calibration can temporarily fix this issue, SPAN now offers an option to read this information directly from the Enphase system, which is more accurate than the estimation. You can learn more about this option here: How do I connect my Enphase to SPAN?
