LG SHB-G1 Automatic Backup Device

The Automatic Backup Device is the piece that turns an LG Prime+ system into a true backup power source. Add it to an SHB-G1 inverter and Prime battery setup and LG's own documentation describes the result as partial or whole-home backup — the alternative Arbitrage Solution swaps this device for a smart meter and skips backup power in favor of self-consumption savings.

LG backs the Automatic Backup Device with the same 10-year warranty it puts behind the inverter and battery when the three are installed together.

• Enables backup mode: Pairs with the SHB-G1 inverter to provide partial or whole-home power during a grid outage.
• 10-year warranty: Covered under the same LG warranty term as the inverter and Prime battery when installed together.
• Retrofit-friendly: Part of LG's plug-and-play Prime+ system, built to add onto an existing solar installation.
