Power outages can happen, especially during hurricanes and blizzards. This means you can’t keep essential appliances and heating running, leading to property damage and safety issues.
For homeowners looking for a dependable home backup generator, the 18kW is one of the most commonly recommended units.
In this review, we’ll explore the pros and cons of the 18kW Generac generator and compare it with other models. Read on to learn whether 18kW is a suitable investment for your home!
18kW Generac Generator Overview
The 18kW Generac home standby generator is a highly-rated backup power source during grid outages. One of Generac’s mid-tier models, the 18kW generator is an ideal choice when you’re looking to power most or all of an average-sized home, depending on the home’s electrical load and whether load management is used.
The Generac 18kW Guardian Series is designed to automatically restore power when an outage occurs. It’s permanently installed outside your home, and connects directly to your electrical system.
Once it detects an outage, the unit uses liquid propane or natural gas and converts it into energy.
This model sits in the sweet spot of Generac’s residential lineup.
It has a higher capacity than the 10kW and 14kW Generac home generators. At the same time, the 18kW is more affordable than the larger 22kW or 24kW units.
Here’s a quick comparison of the Generac automatic standby generators.
Model | Typical Home Type |
10kW, 14kW Guardian Series | Entry-level, for smaller homes |
18kW Guardian Series | Mid-tier, for average to larger homes |
20kW, 22kW, 24kW Guardian Series | Upper mid-tier, for larger homes with heavier electrical loads |
26kW, 28kW Guardian Series | Luxury homes with pools and multiple HVAC systems |
Aside from this, the Generac power generators are also more affordable than premium brands like Kohler. That’s why the 18kW is the preferred model for average houses!

Features of the 18kW Generac Generator
Getting a generator for your home is a significant investment. You’ll want to look beyond the power output to get the most out of your money.
Our tip is to always check for durability, reliability, and ease of use.
To help you get started, here are just a few notable features of the 18kW Generac generator.
1. G-Force Engine
At the core of the 18kW Generac generator is an engine designed for your standby power needs. Unlike some generators that use modified automotive engines, the 18kW Generac generator has a G-Force engine that delivers reliable performance.
What’s great about the 18kW Generac generator’s engine is that it operates even in extreme weather conditions. It doesn’t matter if you’re using it for a few hours or a few days. You can be confident that it’ll provide you with consistent power.
2. True Power Electrical Technology
The 18kW Generac generator is designed to provide clean, stable energy for your home. This is crucial because many modern appliances and smart devices are sensitive to power fluctuations.
Generac’s True Power Technology produces less than 5% harmonic distortion. Meaning, it can power sensitive electronics and microwave-chip-based appliances without issues.
The generator is also quick to respond when your home’s power demands change. Even when you’re constantly turning devices on and off, the 18kW Generac generator’s performance remains consistent.
3. Mobile Link Connectivity

On top of this, the mobile link lets you contact customer service quickly. If you’re having an issue with the generator, Generac has an extensive dealer network that can assist you through the mobile link.
4. Other Safety Features

- Voltage Regulation: The generator regulates the voltage so it can avoid damaging voltage spikes.
