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:
      • 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)
        • Your SPAN-Authorized Installer or Franklin Technician must add the hardware using both the SPAN Installer App and Franklin Installer App as part of the installation/configuration. This must be completed with technician onsite; it cannot be done remotely.
          • An ethernet cable is required for communications between SPAN and the Franklin aGate.
      • Enphase IQ Battery (with Enphase IQ System Controller 1, 2, or 3)*
        *Enphase IQ Battery compatibility requires SPAN Remote Meter Kit accessory
        • Your SPAN-Authorized Installer  must add the hardware using the SPAN Installer App.  This must be completed with technician onsite; it cannot be done remotely.
  • As part of an installation with battery storage systems, SPAN requires either a wired ethernet  communications connection to the battery system (SolarEdge, Tesla, FranklinWH) 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.

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

Before your installer leaves (if they are not a SPAN-Authorized installer), be sure to get the following information from them and submit it to SPAN Support:  

SYSTEM REQUIRED INFORMATION
SolarEdge
  • Total Number of Inverters
  • Lead Inverter Model
  • Inverter Location: upstream of SPAN or SPAN breaker spaces (specify which breaker spaces)
  • Total Number of Batteries
  • DC Array Size
  • Photo of the Leader Inverter’s QR Code
Tesla
  • Total number of batteries
  • Tesla Energy Gateway password 
  • Battery breaker location: upstream of SPAN or SPAN breaker spaces (specify which breaker spaces)
  • Close up photo of the Tesla Energy Gateway Label, with QR code visible for scanning.
  • Solar DC array size (if applicable)
  • Solar inverter brand and model (if applicable)
  • Solar inverter breaker location: upstream of SPAN or SPAN breaker spaces (specific which breaker spaces)

 

SPAN Support will use this information to enable battery backup features in your SPAN Home App within 1 business day of receiving the request.

*For Enphase Customers: After the battery system is added, you’ll see a banner at the top of your SPAN Home App saying “Battery calibration in progress.” Click this and fill out the requested information (using your Enphase App) and you’ll begin seeing your battery data reflected in the SPAN Home App.
