Adding Battery Backup to your SPAN Panel

Updated August 08, 2023 22:45

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 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

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 support@span.io:

SYSTEM	REQUIRED INFORMATION

Close Up Photo of the Remote Meter QR Code (found on side of the Remote Meter) Confirm Solar Connection (is it connected through SPAN Panel, through Enphase IQ System Controller, or is there No Solar?) Confirm CT1 Meter Type (Battery, Solar, Site or None) Confirm CT2 Meter Type (Battery, Solar, Site or None) Confirm CT3 Meter Type (Battery, Solar, Site or None) Solar DC array size (if applicable) Solar inverter brand and model (if applicable) Solar inverter breaker location (if applicable)
FranklinWH	Your SPAN-Authorized Installer or Franklin Technician should be able to add the hardware into your Installer App as part of the installation/configuration.
SolarEdge	Total Number of Inverters Lead Inverter Model Inverter Location (upstream of panel or landed on specific breakers) Total Number of Batteries DC Array Size Photo of the Leader Inverter’s QR Code
Tesla	Total number of batteries Tesla Energy Gateway password (Powerwall only) Backup inverter circuit breaker position in SPAN Close up photo of the Tesla Energy Gateway Label, with QR code visible for scanning.

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.
