Residential Backup Power
Your Home Deserves More Than a Generator
Fortress designs complete residential power security systems — engineered to your property, your loads, and your life. Not a box dropped in a yard.
Our Approach
A Backup Power System Is Not a Product. It's an Engineering Decision.
Most homeowners buy a generator and assume they're protected. They're not. A generator without proper load analysis, automatic transfer, battery integration, and monitoring is a liability — not a solution. Fortress starts with your property, your critical loads, and your tolerance for disruption. Then we engineer a system that actually works when you need it.
Protection Architecture
Four Levels of Residential Protection
Every Fortress residential system is built around one of four protection architectures. Your engineer will recommend the right level based on your property, your loads, and your priorities.
Fortress Core
Essential Protection
Generac Standby Generator System
Critical protection for what matters most. A properly sized Generac liquid-cooled standby generator with automatic transfer switch delivers whole-home coverage from the moment the grid fails — no manual intervention, no decisions under stress.
Includes
- Load analysis & critical circuit mapping
- Generac standby generator (48kW or 60kW, liquid-cooled)
- 200A automatic transfer switch — whole-home
- 24/7 remote monitoring & real-time alerts
- Annual maintenance plan
Best for: Primary residences, vacation homes, moderate outage-risk areas

Expanded Protection
Generac Total Power Management System
Whole-home generator coverage paired with an 18 kWh Generac PWRcell battery for seamless, zero-gap transitions. The battery bridges the gap between outage detection and generator startup — your smart home, medical equipment, and home office never skip a beat.
Includes
- Whole-home load analysis
- Generac standby generator (48kW or 60kW)
- Generac PWRcell 18 kWh battery storage
- Zero-gap automatic transfer switching
- Fuel management & extended runtime planning
- 24/7 remote monitoring & alerts
Best for: Luxury primary residences, home offices, medical equipment, smart home infrastructure

System Components
What Goes Into a Fortress Residential System
Standby Generators
Kohler, Generac, and Cummins commercial-grade units. Properly sized to your actual loads — not the minimum spec.
Battery Storage
Tesla Powerwall, Enphase, and Franklin Electric systems integrated with your generator for seamless, silent transitions.
Solar Integration
Grid-tied and off-grid solar designed to work with your backup system — not bolted on as an afterthought.
Automatic Transfer
Whole-home automatic transfer switches with sub-10-second response. No manual intervention. No decisions under stress.
Intelligent Monitoring
Real-time system health, fuel levels, battery state, and grid status — accessible from any device.
EV Charging Integration
Your electric vehicles stay charged during extended outages. Load-managed to avoid overloading your backup system.
Surge Protection
Whole-home surge suppression protects your electronics, appliances, and smart home infrastructure.
Fuel Management
Propane, natural gas, and diesel configurations. Automatic fuel monitoring and delivery coordination available.
The Fortress Process
How a Residential Fortress System Gets Built
Site Assessment
A licensed engineer visits your property. We map every load, assess your infrastructure, and understand your priorities.
Load Analysis
We calculate your actual power requirements — not estimates. Every circuit, every appliance, every critical system.
System Design
Your engineer designs a system architecture matched to your property, your loads, and your protection level.
Proposal & Review
A detailed proposal with system specifications, timeline, and investment. No surprises.
Permitting
We handle all permits, utility coordination, and inspections. You don't manage paperwork.
Installation
Our licensed installation teams work to your schedule. Clean, precise, and fully commissioned before we leave.
Commissioning
Every system is tested under load before handoff. We verify every transfer, every circuit, every alert.
Ongoing Service
Annual maintenance, 24/7 monitoring, and priority response. Your system stays ready.
