Project Overview
Pete works from home and depends on reliable electricity to stay productive and connected. He was concerned that utility outages would disrupt his work and compromise his home’s food storage and basic systems. To address these concerns, Green Additions designed and installed a comprehensive whole-home backup battery system.
This FranklinWH installation provides 30 kWh of backup power with seamless transition capability, so critical systems—including his home office, refrigeration, and essential circuits—continue operating during grid outages. The system maintains power to loads he designates while safely isolating the home from the utility grid.
Pete’s feedback highlights his confidence in the system’s reliability and the team’s professionalism throughout the installation process. The carefully engineered backup panel and FranklinWH aGate control system make this a model for whole-home energy resilience.

The Problem & The Solution
The Challenge
Pete works from home and couldn’t afford losing power due to utility outages. Beyond work continuity, he worried about:
- Interrupted work sessions and lost productivity
- Food spoilage from refrigeration loss
- Loss of internet and communication systems
- No backup for essential household systems
- Vulnerable to extended outages in his area
The FranklinWH Solution
Green Additions designed a whole-home backup system that provides:
- 30 kWh usable battery capacity for extended outages
- Seamless automatic grid transition with aGate controller
- Protection for home office, refrigeration, and critical circuits
- Backup panel infrastructure for flexible load management
- Professional installation and integration with home systems
How Whole-Home Backup Works
During normal grid operation, the FranklinWH system works silently in the background. When the utility grid fails, the aGate intelligent controller automatically isolates the home from the grid and seamlessly switches to battery power. Designated circuits and systems continue operating without any action required from the homeowner.
Grid Normal
Home runs on utility power while batteries remain charged and ready.
Outage Detected
aGate controller instantly detects grid failure and initiates transition.
Seamless Switch
System isolates from grid and automatically supplies battery power to backed-up circuits.
Backup Power Active
Home office, refrigeration, and essential systems remain powered for hours or days depending on usage.
