LG enblock S 17.7kWh Home Backup System with SHB-G1 Inverter & Automatic Backup Device
This bundle brings together a full 17.7kWh LG enblock S battery stack — five plug-in modules on one Control Unit — with an SHB-G1 hybrid inverter and Automatic Backup Device, for whole- or partial-home backup power in one order. LG built enblock S around a boltless, plug-in connector system a single technician can install in about 15 minutes, and the line carries UL9540A certification for indoor and outdoor installation.
The SHB-G1 inverter couples on the AC side for a maximum output of 9.6kW, and the Automatic Backup Device is what switches your home to battery power during a grid outage — together, they turn a 17.7kWh battery stack into a complete, whole-home-ready backup system.

LG enblock S 17.7kWh Home Backup System with SHB-G1 Inverter & Automatic Backup Device: Frequently Asked Questions
What comes in this bundle?
A full 17.7kWh LG enblock S battery stack (five modules on one Control Unit), an SHB-G1 hybrid inverter, and an Automatic Backup Device — everything needed for a whole- or partial-home backup setup in one order.
How much backup power will 17.7kWh give me?
LG doesn't publish a fixed runtime figure, since it depends on what you're running. A battery this size comfortably rides out a multi-hour outage covering essentials like refrigeration, lighting, and networking; heavier loads like central air conditioning will draw it down faster. Call us at (303) 876-7654 and we'll help size it to your panel.
Can I add more battery capacity later?
Yes. LG supports up to 2 enblock S units running in parallel, for up to 14kW of combined output if one 17.7kWh stack isn't enough.
Is this a whole-home backup system?
With the Automatic Backup Device installed, you can configure it for whole- or partial-home backup depending on your electrical panel and priorities.
How long does installation take?
LG's plug-in connector design lets a technician install the battery stack in about 15 minutes, and LG reports full inverter and battery commissioning in under 10 minutes. A licensed electrician still needs to handle the full system integration and any permitting your area requires.
Is this UL certified?
The enblock S battery carries UL9540A and UL1973 certification for indoor and outdoor installation. LG doesn't publish a separate public certification listing for the SHB-G1 inverter — call us and we'll get you that documentation before you order.
Do I need a separate smart meter?
No. The Automatic Backup Device replaces the smart meter LG uses in its Arbitrage-only configuration. This bundle is built for backup power, not just self-consumption savings.
Do you offer financing or price matching?
Yes. We offer 0% APR financing through Affirm at checkout, and our Lowest Price Guarantee applies. If you find this LG equipment cheaper at another authorized LG dealer, call us at (303) 876-7654 before you order and we'll take care of it.
Are you an authorized LG dealer?
Yes. Renewable Outdoors is an authorized LG Energy Solution dealer, and every unit we sell ships new, in factory packaging, with LG's warranty intact.
Where can I find full documentation for this system?
Call us at (303) 876-7654 and we'll get you the installation manual and warranty registration materials directly from LG.
