What Solar & Storage Systems is SPAN compatible with?

  • Updated

Solar-only Systems

SPAN may be paired with any grid-tied solar inverter. No communication wiring is required between SPAN and solar systems without battery backup. The circuit breaker feeding the solar inverter must be installed in your SPAN Panel to allow SPAN to monitor your solar production.

Solar & Storage Systems

SPAN is currently compatible with the following battery storage systems. We are continually working to expand our integrations to support more storage systems in the future -- Stay tuned!

  • LG Chem RESU and SolarEdge Energy Bank (with SolarEdge Energy Hub Backup Interface)* 
    * SPAN is compatible with up to 3 Energy Hub inverters
  • Tesla Powerwall and Powerwall+ (with Backup Gateway 1, Backup Gateway 2, or Backup Switch)

As part of an installation with battery storage systems, SPAN requires a wired communications connection to the battery system to ensure robust functionality correctly during an outage. Details for your SPAN-certified installer can be found on the SPAN Partner Portal.

We take home backup seriously.

Delivering reliable power—especially during outages—is essential. At SPAN, we intentionally evaluate every backup system we integrate with. This includes extensive performance testing and establishing direct communications between SPAN and the storage system to enable backup prioritization, system monitoring, and predictive algorithms. This means to deliver the absolute best backup experience, we do not support installation with non-integrated battery backup systems where this essential functionality is missing. Today SPAN's compatible with the market-leading, field-proven home battery systems covering 80% of the market, and we're constantly evaluating new ones! 

Do I still need a Tesla Gateway or SolarEdge Backup Interface grid disconnect?

Yes, SPAN is designed to work alongside a Tesla Backup Gateway or a SolarEdge Backup Interface. Today, these 3rd party Grid Disconnect devices are still required for Powerwall or SolarEdge backup systems. However, by adding SPAN’s intelligent load management, many customers find that fewer batteries are needed to last through an outage.

Standby Generators

SPAN may be installed with Standby Generators in a limited capacity. Please see our Generator Guidance and Recommendations for more information.

SPAN Drive

What Battery Storage Systems are compatible with SPAN Drive?

SPAN Drive is compatible with all battery backup systems that are compatible with the SPAN Panel.

SPAN is currently compatible with SolarEdge Energy Hub and Tesla Powerwall battery storage systems. We are continually working to expand our integrations to support more storage systems in the future.

Can I get the same features and functionality with other EV chargers?

For now, all SPAN Drive functionality is only available with SPAN hardware products. Other EV chargers may be installed with SPAN, but will not offer the full set software features to charge faster, cleaner, and smarter!
