Florida homeowners know that power outages are more than a minor inconvenience. From hurricane-related blackouts to unexpected utility failures, having a backup power system can make all the difference in safety, comfort, and peace of mind.
But what’s the right choice for your home—a portable generator or a standby generator?
Let’s break down the real-world pros, cons, contractor requirements, and Florida-specific considerations so you can choose confidently.
Overview: What’s the Difference?
Portable Generators
Portable generators are compact, movable units typically powered by gasoline or propane. Though they seem simple, safe home use requires professional electrical work, including an inlet and manual transfer system.
Power Output: 3–15+ kW Use Case: Short outages, powering essentials Fuel: Gasoline or propane (stored on-site)
Standby Generators
Standby generators are permanent fixtures wired directly to your electrical system. They power your home automatically during an outage and run on propane or natural gas from your utility or a tank.
Power Output: 10–26 kW Use Case: Long-term outages, full-home or partial backup Fuel: Natural gas or propane (hard-piped)
Contractor Requirements (Florida)
Task
Portable Generator
Standby Generator
Electrical Contractor
✅ Required – to install inlet box & transfer switch
✅ Required – to connect generator to home panel
Gas Contractor (LP/Natural)
❌ Not usually needed (fuel is portable)
✅ Required – to connect to gas utility or tank
HVAC Technician
⚠️ Not always - needed if soft start system will be used to run A/C
✅ Recommended – if HVAC systems are tied into backup
Structural Contractor
❌ Not needed
✅ May be required – to pour concrete pad or platform
Permits Required
⚠️ Almost always
✅ Always – electrical + gas + possible zoning permits
HOA Approval
❌ Unlikely
⚠️ Often required – especially in deed-restricted communities
Pro Tip: Always check with your local permitting office and HOA before purchasing a standby generator. Enclosures, sound levels, and placement are often regulated.
Portable vs. Standby: Detailed Comparison
Feature
Portable Generator
Standby Generator
Initial Cost
$700–$2,000+ for unit + $800–$1,500+ for safe install
$5,000–$20,000+ (installed and permitted)
Power Output
3–15+kW – Fridge, lights, electronics small AC (varies by size)
10–26 kW – Whole home including HVAC
Startup
Manual (but push-button and electric start are available)
Fully automatic within seconds of outage
Fuel Source
Gasoline or propane – must be refilled manually
Natural gas (utility) or large propane tank
Noise Level
Inverter models are quieter; large units can be loud
Quieter, sound-insulated enclosures
Installation
Requires pro installation for inlet & transfer switch
Requires pro install, gas hookup, and pad
Permits Required
Yes (for electrical)
Yes – electrical, gas, structural, HOA approval
Mobility
✅ Portable—but some units weigh over 100 lbs and require wheels or carts
❌ Fixed installation only
Maintenance
Owner-performed (oil changes, spark plugs)
Needs professional maintenance (every 6–12 months)
Important Considerations
Installation for Portable Generators
Even though they’re portable, using a generator to safely power your home circuits requires:
Electrical permit
A generator inlet box (usually 30A or 50A)
A manual transfer switch or breaker interlock kit
Professionally installed wiring from inlet to panel
Weather-rated cover if placed outdoors
Total installed cost:$2,000–$5,000+ including generator, depending on complexity and local labor rates.
Installation for Standby Generators in Florida
Standby generator projects in Florida require:
Electrical permit (panel integration with ATS – Automatic Transfer Switch)
Gas permit (for natural gas or propane connection)
Zoning approval (setback rules, noise limits)
Flood elevation compliance (e.g., raised platform in flood-prone areas)
Concrete pad or hurricane-rated mounting system
HOA approval in many deed-restricted communities
Example: Some HOAs limit generator noise to <70 dB and require that the unit be screened with landscaping or fencing.
Total installed cost:$5.000–$20,000+ including generator, depending on complexity and local labor rates.
Weight & Mobility: Don’t Overlook This!
While "portable" sounds convenient, these units can still be heavy:
3–6 kW generators: <80–100 lbs
7–15kW models: ~150–250 lbs
Pro Tip: Look for models with wheels, fold-down handles, and electric start to make operation easier. Storing the generator and moving it into position can be a chore, especially during a storm.
Generator Sizing: What Do You Really Need?
Here’s a rough power breakdown to help you size your system:
nce/System
Approx. Watts (Running)
Refrigerator
600–800 W
Window AC Unit
1,000–1,500 W
Central AC (3-ton)
3,500–4,500 W
Electric Water Heater
3,000–4,500 W
Wi-Fi + Lights
500–1,000 W
Portable: Good for 1–2 appliances + the basics + A/C when used in conjunction with a soft start system Standby: Can run the whole home, including HVAC, water heater, washer/dryer, etc.
If you’re looking for affordability and flexibility, a portable generator (properly installed) could be a great fit—just be ready to manage fuel, setup, and storage.
If you want hands-off operation, full-home coverage, and peace of mind during long outages, a standby generator is the gold standard—especially in storm-prone areas like Florida.
Either way, partner with licensed professionals and check local codes and HOA rules to avoid costly surprises.
