Power Outage Proof: How to Choose the Right Backup Generator Setup

How to Prepare Your Home for a Backup Generator
Power outages in Brooklyn can last hours or days. Whether from summer storms, winter ice, or grid failures, losing power means losing:
- Refrigerated food
- Heating/cooling
- Security systems
- Medical equipment
- Work-from-home ability
- Basic comfort
A backup generator solves these problems. Here's how to choose and prepare.
Types of Backup Generators
Portable Generators
What they are: Gas-powered units you roll out during outages
Power output: 3,000-12,000 watts
Cost: $500-2,500
Pros:
- Lower upfront cost
- Flexible use (camping, job sites)
- No installation required
Cons:
- Must be set up each time
- Requires manual start
- Fuel storage needed
- Can only power select circuits
- Must refuel during long outages
- Carbon monoxide risk if used improperly
Standby (Whole-House) Generators
What they are: Permanently installed units that start automatically
Power output: 10,000-48,000 watts
Cost: $3,000-15,000 + installation
Pros:
- Automatic operation
- Powers entire home
- Runs on natural gas or propane (no refueling)
- Seamless transition (10-30 seconds)
- Increases home value
Cons:
- Higher upfront cost
- Professional installation required
- Requires permits
- Needs regular maintenance
Battery Backup Systems
What they are: Large batteries that store power for outages
Power output: Varies (Tesla Powerwall: 13.5 kWh)
Cost: $10,000-20,000 installed
Pros:
- Silent operation
- No fuel required
- Can charge from solar
- No emissions
- Low maintenance
Cons:
- Limited runtime
- High upfront cost
- May not power whole home for long
Sizing Your Generator
Step 1: List Essential Circuits
Must-have during outage:
- Refrigerator: 600-800W running, 2,000W starting
- Sump pump: 800W running, 2,500W starting
- Furnace: 300-500W
- Well pump: 1,000W running, 3,000W starting
Nice to have:
- Lights: 100-500W (LED much less)
- TV/Internet: 200-400W
- Microwave: 1,000-1,500W
- Computer: 200-400W
High draw (may skip):
- Central AC: 3,000-5,000W
- Electric water heater: 4,500W
- Electric stove: 2,000-5,000W
- Space heaters: 1,500W each
Step 2: Calculate Total Load
Running watts: Add up everything you want to run simultaneously
Starting watts: Add highest starting wattage item
Example:
- Refrigerator: 800W running + 2,000W starting
- Lights: 300W
- Furnace: 400W
- TV/Internet: 300W
Running total: 1,800W
Starting needs: 1,800W + 2,000W = 3,800W
Generator needed: At least 4,000W (recommend 5,000-6,000W for headroom)
Step 3: Choose Generator Type
For essentials only: 5,000-7,500W portable
For most of home: 10,000-14,000W portable or small standby
For whole home: 16,000-24,000W standby
For whole home with AC: 24,000-48,000W standby
Preparing Your Home for Generator Installation
Electrical Preparation
For Portable Generators:
1. Install a transfer switch ($300-600 installed)
2. This prevents backfeeding into grid (dangerous and illegal)
3. Allows safe connection to home circuits
4. Creates simple switching between grid and generator
For Standby Generators:
1. Install automatic transfer switch (ATS)
2. May need panel upgrade
3. Dedicated circuits for generator
4. Proper grounding
Site Preparation
Location requirements:
- 5+ feet from windows, doors, vents
- On stable, level surface
- Protected from flooding
- Accessible for maintenance
- Compliant with local codes
For standby generators:
- Concrete pad (typically included in install)
- Gas line connection
- Electrical connection
- Sound considerations for neighbors
Permits and Approvals
NYC requirements:
- Electrical permit for transfer switch
- DOB approval for standby generator
- Gas permit if natural gas
- Some co-ops/HOAs require approval
