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.
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.
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!
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.
SPAN may be installed with Standby Generators in a limited capacity. Please see our Generator Guidance and Recommendations for more information.
Today, all SPAN Drive functionality is only available with the SPAN Drive hardware. Other EV chargers may be installed with SPAN Panels, but will not offer the full set of features or the ability to charge faster, cleaner, and smarter.
