Adding Battery Backup to your SPAN Panel

  • Updated

What to know before adding battery backup to your SPAN panel

  • SPAN is designed to replace the critical loads panel in a battery backup system.
  • SPAN is compatible with the following backup systems:
      • LG Chem RESU and SolarEdge Energy Bank (with SolarEdge Energy Hub Backup Interface)*
        *SPAN can be paired with up to 2 Energy Hub inverters
      • Tesla Powerwall and Powerwall+ (with Backup Gateway 1, Backup Gateway 2, or Backup Switch)
      • FranklinWH aPower (with aGate)
      • Enphase IQ Battery (with Enphase IQ System Controller 1 and 2)*
        *Enphase IQ Battery compatibility requires SPAN Remote Meter Kit accessory
  • As part of an installation with battery storage systems, SPAN requires either a wired communications connection to the battery system (LG, SolarEdge, Tesla) or SPAN Remote Meter Kit (Enphase) to ensure robust functionality during an outage.

Preparation

Provide the appropriate one-page Battery Addition Guide to your installer before installation day so they know what to expect. If they have any questions, please direct them to contact SPAN Support.

Adding SolarEdge Energy Hub Storage to SPAN

Adding Enphase IQ Battery Storage to SPAN

Make sure your installer knows that you’ll need a hardwired communications cable between SPAN and your backup system or SPAN Remote Meter Kit so it can be included in the scope of work, and they come prepared with the right materials.

Installation Day
