When the power goes out, having a reliable portable generator ensures your home stays powered, keeping essentials like lights, refrigerators, and heating systems running. While standby generators offer seamless backup power, they come with a hefty price tag—often exceeding $12,000 after installation. A well-chosen portable generator paired with the right accessories (like an interlock kit, inlet box, and generator cable) provides a cost-effective and flexible alternative for home backup power in the case of an emergency.
In this guide, we’ll cover five top portable home generators, the difference between 30A and 50A setups, and must-have accessories, including trickle chargers and why tri-fuel generators are the best alternative to a standby unit.

4. Firman T07571:
Another tri-fuel option, the Firman T07571, offers 9,400 peak watts and 7,500 running watts, making it the transition point from 30A to 50A setups. Many generators below 7,500 running watts use a 30A connection, but once you cross that threshold, a 50A connection is necessary to handle higher power loads. This portable home generator is a great options and is one of the more affordable home portable generators starting $1,299.99.
5. Predator 9500 Inverter Generator:
Finally, the Predator 9500 Inverter Generator combines high power output (9,500 peak watts, 7,600 running watts) with inverter technology, providing stable, clean power. It’s quieter than traditional generators while offering the efficiency needed for whole-home backup. Beginning at $2,299.99.
Understanding 30A vs. 50A Generator Setups
One of the most important aspects of setting up a portable generator for home backup power is choosing between a 30A and 50A connection. This decision determines how much power your home can draw from the generator and which appliances you can run simultaneously.
30A Generator
One of the most important aspects of setting up a portable generator for home backup power is choosing between a 30A and 50A connection. This decision determines how much power your home can draw from the generator and which appliances you can run simultaneously.
A 30A setup typically supports up to 7,500 running watts, making it suitable for powering essential appliances like refrigerators, lights, sump pumps, and small heating systems. Generators with a 30A outlet use an L14-30 plug, and the corresponding inlet box and power cable must match.
50A Generator
Once your generator exceeds 7,500 running watts, you’ll likely need a 50A setup, which can power larger loads, such as an HVAC system, multiple refrigerators, or an electric water heater. A 50A generator uses a CS6365 plug, which requires a 50A inlet box and power cord. Many higher-output generators include both 30A and 50A outlets, allowing for flexibility in your setup.
To summarize the difference between generator setups, If you only need to power basic home essentials, a 30A setup is sufficient. However, if you want to power multiple large appliances at once, a 50A setup is the better option.
Must-Have Accessories for a Safe and Reliable Home Generator Setup:
A generator alone isn’t enough—you’ll need the right accessories to connect it safely and efficiently to your home. The most important component to your home generator is an interlock kit, which allows you to safely connect your generator to your home’s electrical panel. Unlike a transfer switch, an interlock kit is a cost-effective solution that lets you choose which home circuits receive power. More importantly, it prevents dangerous backfeeding into the electrical grid, protecting both your home and utility workers while allowing more breakers than the standard 10 that you would get from a transfer switch.
To connect your generator to your home, you’ll need a generator inlet box, which provides a safe, outdoor connection point for generator power. Make sure you choose the correct 30A or 50A version depending on your generator’s power output. A weatherproof, UL-listed inlet box is best for long-term reliability. Choosing a larger inlet box will make it easier for an electrician to install because of the wiring behind the receptacle.
A generator power cable is also essential, as it links your generator to your inlet box. For 30A setups, use an L14-30 cable, while 50A setups require a CS6365 cable. These cables should be heavy-duty and outdoor-rated, and you should keep your generator at least 10-25 feet away from your home to prevent carbon monoxide exposure.
Trickle Chargers: Keep Your Generator Ready at All Times
One of the most common issues with portable generators is finding a dead battery when you need it most. A trickle charger ensures that your generator’s battery stays fully charged, so it’s ready to start during an emergency. Smart trickle chargers only deliver power when needed, preventing overcharging and battery damage.
Why Tri-Fuel Generators Are the Best Alternative to Standby Units
For homeowners looking for a whole-home backup power solution without spending thousands on a standby generator, tri-fuel generators are the best alternative. Running a generator on natural gas eliminates the need for fuel storage, providing unlimited runtime and making a tri-fuel setup function similarly to a standby generator. With a 50A inlet box and an interlock kit, a tri-fuel generator can power your whole home just like a standby unit—but at a fraction of the cost. While a standby generator installation typically costs over $12,000 or more, a tri-fuel portable generator setup is under $3,000.
Choosing the Best Home Generator for You
A portable generator with the right accessories provides a cost-effective way to keep your home powered during an outage. While it requires manual operation, including starting the generator and switching power using an interlock kit, it eliminates the high installation and maintenance costs of a standby system. By choosing the right home generator size (30A or 50A setup) and ensuring a safe connection with an inlet box and power cable, you can power essential appliances or even most of your home at a fraction of the price of a standby unit.
