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
