Generac 18kW Home Standby Generator, Cellular Connectivity, Easy To Use, Whole House Power Backup, Smart Outage Solution
Most important from
1 reviews
The Generac 18kW Home Standby Generator is designed to provide reliable, whole-house backup power during outages, making it a strong choice for homeowners wanting to keep essential systems like heating, cooling, and refrigeration running smoothly. With an 18,000-watt output, it can comfortably handle most residential power needs. It runs on fuel such as natural gas or propane, and its smart fuel and ignition controls help optimize usage, which can save money and reduce emissions over time.
A standout feature is the built-in cellular connectivity, allowing you to monitor and control the generator remotely through a smartphone app, adding convenience and peace of mind. The generator automatically detects power outages and switches on quickly via its automatic transfer switch, ensuring minimal disruption. Noise levels are described as 'super quiet,' making it well suited for residential areas. Due to its weight of 426 pounds and size, portability is limited, positioning it as a more permanent installation rather than a moveable option. Additional features like oil level sensors and cold-start support enhance reliability, especially in colder climates. Compatibility with other home energy products from Generac offers benefits for those seeking a connected energy system.
The main considerations include its large size and installation requirements, which may necessitate professional setup and make it less suitable if a portable or easily moved generator is desired. Additionally, some advanced features require a paid subscription. For anyone seeking a dependable, automated backup power solution that covers the whole house and provides remote management, this generator is an excellent match, especially for users prioritizing convenience and reliability over portability.

DuroMax XP16000iH 16,000-Watt Dual Fuel Portable Digital Inverter Generator - Gas & Propane, Remote Electric Start, Whole Home Power Backup, Transfer Switch Ready, RV & Emergency Ready
Most important from
24 reviews
The DuroMax XP16000iH is a powerful home backup generator offering up to 16,000 starting watts and 13,000 running watts, which is more than enough to power essential household appliances during outages. It runs on both gasoline and propane, giving you flexible fuel options that can be useful depending on availability or storage preferences. The generator features inverter technology, providing clean and stable power that's safe for sensitive devices like computers and TVs. A handy remote electric start and a digital control center with an LCD display add convenience for operation and monitoring. It also includes a Battery Tender to keep the battery charged and a low oil shutoff feature to protect the engine.
The 10.5-gallon fuel tank supports around 10 hours of runtime, which suits long power outages. This model is transfer switch ready, making it easier to integrate with your home's electrical system for automatic power backup. Portability is limited due to its heavy weight of 368 pounds, so it’s better suited for stationary use rather than frequent moving. Generators of this size typically operate at higher noise levels, which may be a consideration for residential areas.
Certified to meet environmental standards, the size and weight of this model make it ideal for those who need substantial, reliable power at home or work sites and can manage its bulk. For users seeking a robust dual fuel generator with easy starting and strong output, the DuroMax XP16000iH is a solid choice, though it’s less convenient if you want something lightweight or very quiet.

Honda EU7000IS 7,000 Watt Inverter Portable Backup Generator, Super Quiet, Electric Start
Most important from
29 reviews
The Honda EU7000IS is a solid choice for anyone needing a backup generator for home use, outdoor events, or RV trips. With a power output of 7,000 watts and a running wattage of 5,500 watts, it can handle a variety of electrical loads, making it versatile for different needs. One of its standout features is the super quiet operation, which is a big advantage for residential areas where noise can be a concern.
Additionally, the electric start makes it easy to operate, especially for those who might struggle with manual starts. The included Honda My Generator app with Bluetooth capability allows for convenient monitoring, which is a modern touch that enhances usability. The CO-MINDER system is also an important safety feature, providing advanced carbon monoxide detection.
On the downside, the generator weighs 270 pounds, which may hinder portability for some users, and its runtime of 6.5 hours at full load could be insufficient for longer power outages. While the fuel efficiency is praised, larger fuel tanks could improve the runtime significantly. It also lacks an Automatic Transfer Switch (ATS), which would have added convenience for automatic operation during power failures. The warranty is decent at three years, offering some peace of mind.
