Whole-Home Generator
Installation
Never go dark again. We install permanent, automated standby generators and transfer switches to keep your home powered through extreme weather across the DMV.
Uninterrupted Power Security
Mid-Atlantic ice storms and summer hurricanes frequently cripple the utility grid. Hauling out a portable generator in the rain is dangerous and inconvenient. A Whole-Home Generator Installation provides a permanent, hands-free solution. The system detects an outage and restores full power to your house in under 15 seconds.
Auto Transfer Switches
The brain of the system. The ATS safely disconnects your home from the dead grid and seamlessly switches over to generator power.
Load Shedding
Smart management modules that temporarily pause heavy appliances (like AC units) so you can run the rest of the house on a smaller generator.
Fuel Integration
Standby units plumb directly into your home's existing Natural Gas or Liquid Propane supply, running indefinitely without refueling.
Generac & Kohler
We specialize in the wiring, trenching, and panel integration of industry-leading, heavy-duty standby equipment.
Standby Infrastructure Specifications
Automatic Transfer Switches
The ATS is the most critical safety component. It acts as an impenetrable wall between utility power and your generator to prevent lethal backfeeding.
Service Rated ATS
Full 200-amp transfer switches installed between the meter and panel.
Utility Isolation
Mechanically blocks backfeeding electricity onto public power lines.
Voltage Sensing
Monitors utility voltage 24/7; triggers auto-start in seconds.
Exterior Housings
Weatherproof enclosures for mounting the ATS outside the home.
Control Wires
Pulling low-voltage communication lines from the ATS to the engine.
Essential Load Panels
Installing sub-panels for smaller units to power only critical circuits.
Mobile Link
Connecting the system to Wi-Fi for remote monitoring and alerts.
NEC 702 Compliance
Adhering to Optional Standby Systems code for residential use.
Load Calculation & Shedding
Generators must be perfectly sized. We calculate the exact starting wattage of your appliances and install smart modules to prioritize power.
Kilowatt Sizing
Factoring HVAC inrush, well pumps, and continuous appliance loads.
Smart Management Modules
Devices that temporarily block AC units if the generator nears overload.
Starting Wattage
Calculating the massive 3x power spike needed to start electric motors.
Soft Starts
Installing AC compressor soft-starts to reduce generator strain by 60%.
Priority Lockouts
Ensuring critical items (fridges/sump pumps) always get power first.
Total Harmonic Distortion
Ensuring the power is "clean" (<5% THD) to protect smart TVs.
Phase Balancing
Distributing load evenly across the 240V generator stator.
Hybrid Systems
Integrating generators with whole-home battery backup arrays.
Trenching & Placement
Large generators cannot sit against the house. We trench heavy-gauge wire and pour structural pads to meet strict fire and noise codes.
Window Clearances
Mounting units 5ft from openings to prevent Carbon Monoxide entry.
Underground Routing
Trenching PVC conduit from the generator pad back to the ATS.
Waterproof Wiring
Pulling heavy-gauge nylon-jacketed wire rated for wet environments.
Concrete Pads
Pouring reinforced pads or installing specialized composite platforms.
Miss Utility Prep
Coordinating safe digging around existing yard infrastructure.
Plumbing Prep
Coordinating exact trenching routes for your gas plumber's tie-in.
Acoustic Placement
Positioning units away from property lines to meet HOA decibel rules.
Foundation Sealing
Waterproofing the core drilling points where conduit enters the basement.
Engine & Alternator Tech
We wire and integrate premium standby equipment. These are industrial-grade motors designed to run continuously for weeks if necessary.
Air-Cooled (up to 24kW)
Standard V-Twin residential units suitable for most 200A homes.
Liquid-Cooled (25kW+)
Automotive-style engines for massive luxury estates and commercial loads.
Natural Gas / LP
Wiring systems configured to run on continuous municipal gas or propane.
Brushless Alternators
High-efficiency power generation with zero sparking components.
Weekly Exerciser
Programming the system to run a 5-minute self-test every week.
Corrosion Enclosures
Aluminum housings that withstand salt-air and severe weather.
Starting Batteries
Installing heavy-duty cold cranking amp batteries for reliable starts.
Cold Weather Kits
Adding battery warmers and oil block heaters for freezing MD winters.
Portable vs. Standby
Portable generators require you to store dangerous gasoline, drag the unit outside in a storm, and run messy extension cords. A permanent standby unit is fully automated, runs on your home's gas line, and produces "clean" power that won't fry your sensitive electronics.
Standby Power FAQs
No. The Automatic Transfer Switch (ATS) monitors the utility lines constantly. The moment it detects a drop in voltage, it automatically turns on the generator, isolates your home from the grid, and restores power within 10 to 15 seconds. It reverses the process automatically when utility power returns.
Generators are measured in Kilowatts (kW). The size you need depends on whether you want to power the entire house or just the "essentials." Here is a standard technical sizing guide.
| Generator Size | Supported Amperage | Typical Appliance Load Capability |
|---|---|---|
| 10 kW - 14 kW | ~50 Amps | Essentials Only: Fridge, Well Pump, Lights, Router (No Central AC) |
| 18 kW - 22 kW | ~90 Amps | Standard Home: Essentials + One 4-Ton Central AC Unit |
| 24 kW - 26 kW | ~100+ Amps | Large Home: Multiple HVAC units, Electric Ovens, Sump Pumps |
| 30 kW+ (Liquid) | ~125+ Amps | Luxury Home: Full operation of all appliances, pools, and EV chargers |
An ATS is a strict NEC and utility requirement. It physically breaks the connection between your house and the public power grid before the generator kicks on. Without it, your generator would "backfeed" electricity onto the street lines, electrocuting the linemen trying to fix the outage.
As master electricians, Eminent Power Solutions handles 100% of the electrical trenching, panel integration, and transfer switch wiring. We coordinate closely with licensed plumbers who handle the final natural gas or liquid propane tie-in to ensure every aspect is handled by a specialized master tradesman.
Just like a car engine, generators require regular oil changes, spark plug replacements, and air filter swaps. Most manufacturers recommend a professional service interval every 12 months or after 100 hours of continuous use during a major outage.
