Best Home Standby Generator: Generac Guardian 7209 

Built in the United States, the Generac Guardian 7209 is the gold standard for home standby generators. Boasting up to 24kW of power, the Guardian can be set up to run on either natural gas or liquid propane as a fuel source (but you must decide this at installation time).

Once installed, this unit is more than capable of quickly and automatically powering all your home's essentials plus extras during a power grid failure. Pair it with a service disconnect automatic transfer switch to get AC shedding for up to four HVAC systems. That means you'll be able to prioritize which circuits get power. The transfer switch can automatically cut power to an HVAC system if there's too much load on the generator from your priority appliances.

The Guardian works with Generac's Mobile Link™ Wi-Fi remote monitoring application, which monitors the generator's status on a smartphone, tablet, or PC. This is extremely useful if you're at work or out of town during a power outage and want to make sure everything is working properly. Simple on-unit digital controls, including a programmable exerciser, let you set how often and at what time the generator will self-test.

You can count on the Guardian to last with Generac's G-Force engine and a full-pressure lubrication system that keeps the parts moving smoothly. Its durable, all-aluminum sound-reducing enclosure shields internal components from the elements and significantly reduces noise. Finally, a 5-year Generac limited manufacturer's warranty protects your investment from defects. All-in-all, virtually no one can go wrong by choosing this home generator.

Application Readiness

-Great for whole-home backup -Runs on propane or natural gas  -Durable, sound attenuated enclosure

Usability

-Works w/ WiFi remote monitoring -Can be installed 18-in from a structure -Quiet self-test mode -Automatic digital voltage regulation

Best Solar Generator EcoFlow DELTA Max 2000

The EcoFlow DELTA Max 2000 is a perfect example of how solar generators are becoming a viable alternative to gas-powered units. With a 2,016-watt-hour lithium battery pack that can provide 2,400 running watts and 5,000 starting watts, the DELTA Max 2000 can handle everything from camping to basic home backup. You can even parallel multiple units for extra power. Plus, DELTA Max has a unique technology called “X-Boost,” which can provide a 3,400-watt surge of power if you need it (although this will quickly drain the battery).

Charging is a cinch with the ability to use solar panels, a wall outlet, or a car charger. Using a wall outlet, the DELTA will fully charge in under two hours, which is among the fastest charging times I’ve seen. For solar charging, you can connect up to two 400-watt EcoFlow solar panels or use the MC4 connector if you have other panel brands. Charging speed will vary depending on the solar panels you use.

Once charged, its battery has a one-year shelf-life, so it’ll be ready to go when the next power outage hits. Thirteen outlet receptacles let you plug in standard wall plugs and USB cables. At only 48 pounds, this generator is easy to take where you need it, and you can even control and monitor everything remotely using the wireless EcoFlow app. Overall, the DELTA Max 2000 is a powerhouse without the noise, fumes, or maintenance that comes with gas-powered generators. The relatively low price makes this an even better catch.

 

Power

-2,400 running/5,000 starting watts -X-Boost allows continuous surge of 3,400 watts -2,016-Wh lithium battery pack w/ expandable capacity to 6,000Wh

Usability

-Fully charges in under 2-hrs via wall outlet -1-year shelf life at full charge -Compact design & weighs 48 pounds for easy storage & transport -Works with EcoFlow app for control/monitoring -Safe for electronics

Versatility

-Charges on AC, DC, or solar power -Compatible with EV charging stations -Multiple output receptacles including NEMA 5-15R, USB-A, USB-C & car power output

Overall Value

Hassle-free power source with a relatively inexpensive price tag.

 

Solar and battery technology has come a long way, and you can now power your essentials using a portable power station, commonly called a solar generator. No combustion means you can run these units indoors or outdoors, and they are almost silent. Step into the future today!
