This feature provides added peace of mind when you’re away from home.
Carbon Monoxide (CO) Protection
Modern portable generators often include carbon monoxide shutdown systems.
If dangerous CO levels are detected around the generator, it automatically shuts off.
Always operate portable generators outdoors in a well-ventilated location. Never run a generator inside a garage, basement, crawl space, or enclosed building. Position it well away from doors, windows, and vents.
Runtime
Long runtime becomes extremely important during extended outages.
Compare:
- Fuel tank size
- Battery capacity
- Runtime at 25% load
- Runtime at 50% load
Longer runtime means fewer refueling or recharging interruptions.
Common Buying Mistakes
Avoid these common mistakes before investing in emergency backup power.
Buying Too Small
Many homeowners underestimate how much electricity they actually need.
Always calculate:
- Running watts
- Starting watts
- Refrigerators
- Freezers
- Well pumps
- Sump pumps
- Air conditioners
- Medical equipment
Buying slightly more capacity provides room for future needs.
Buying More Than Necessary
Not every home requires a whole-house standby generator.
If your goal is simply to power:
- Phones
- Routers
- Refrigerators
- Lights
- Medical devices
A portable generator or power station may be the better investment.
Ignoring Fuel Availability
Fuel becomes one of the biggest challenges during extended outages.
Think about:
- Gasoline availability
- Propane storage
- Natural gas service
- Solar charging capability
Planning ahead helps avoid unnecessary stress during emergencies.
Forgetting Maintenance
Every backup system requires some level of maintenance.
Portable generators should be:
- Exercised monthly
- Given regular oil changes
- Kept fueled properly
- Stored correctly
Battery systems should also receive periodic software updates and system inspections when recommended by the manufacturer.
Waiting Until Storm Season
Generators and battery systems often become difficult to find before hurricanes, ice storms, and major weather events.
Buying early allows you to:
- Compare more models
- Install transfer equipment
- Learn safe operation
- Test your system
- Build emergency fuel supplies
Preparing before severe weather arrives is always the best strategy.
