Hurricane season resources

Hurricane season is in full swing and we want everyone to stay safe. Here are some resources if you or a loved one are impacted by the coming storm.

Because they emit no carbon monoxide and don’t use flammable gasoline, solar generators are a much safer alternative to traditional gas generators. But the benefits don’t stop there—solar-powered generators are also easier to start, quieter, lower maintenance, and, of course, kinder to the environment.

Our favorite solar generator for emergency backup power is the EcoFlow Delta Pro. It combines a fast solar charge time with a generous 3.6 kWh capacity, can directly power your home’s electrical panel, and supports additional batteries for a total capacity of 25 kWh. Better yet, it’s not even the heaviest or most expensive option on our list.

Best solar generators reviews

1. EcoFlow Delta Pro: Overall best for homes

Best for homes

Amazon.com price as of post date. Read full disclaimer.

Everything about the EcoFlow Delta Pro makes it ideal for powering your home’s essentials during an outage. It integrates directly with your existing electrical panel through EcoFlow’s Smart Home Panel (sold separately) to supply continuous power through up to 10 circuits. Even without that integration, the Delta Pro’s 15 outlets should be more than enough to get you through an emergency.

You may need more than one Delta device to reach the 10-circuit maximum capacity, but that brings us to another swoon-worthy feature of this EcoFlow line: chainability. By connecting up to six Delta generators or batteries, you can create a total of 25 kWh of power—the highest kWh rating we encountered in our research. 

The Delta Pro solar generator recharges in up to six hours with four solar panels. It’ll recharge even faster if you have the opportunity to plug it into an AC adapter or an electric vehicle charging station.

Finally, the EcoFlow Delta Pro offers all of these features at one of the most affordable prices on the market. While it certainly still costs a solid chunk of change, you get a lot of power for the money.

2. Bluetti EP500Pro: Best power charge

Best power charge

Amazon.com price as of post date. Read full disclaimer.

The Bluetti EP500Pro takes about five hours to charge over 5 kWh of power—an incredible combination of fast solar charging and high power that’s tough to find. We also love that the Bluetti offers home integration for immediate backup power during a blackout.

con Very heavy (182 lbs)

If you need more than 5 kWh total, it’s super easy to add another Bluetti EP500Pro with a plug-and-play fusion box. 

This solar generator pairs with up to three solar panels, so it has a smaller overall footprint than other models. We love that it connects to Wi-Fi for easy firmware updates, and it even comes with an app that lets you check its power consumption and charge. Plus, there are two wireless charging pads on top of the generator. 

It’s a solar generator you don’t want to take camping simply because it weighs 182 lbs. However, it has wheels to help you move it around the house if you don’t choose the integration option.

3. Jackery Explorer 3000 Pro: Value pick

Value pick

Amazon.com price as of post date. Read full disclaimer.

When equipped with a full set of six solar panels, the Jackery Explorer 3000 Pro (which comes with just two solar panels) charges in under three hours and has a 3 kWh capacity after a full charge. But because it lacks a home integration system and doesn’t support daisy chaining for increased capacity, this Jackery solar generator isn’t our favorite option for emergency use. However, its price is more palatable than its competitors.

con Not chainable

On a single charge, the Jackery Explorer 3000 Pro can run a refrigerator for up to three days. And because it recharges so quickly, you shouldn’t experience a power disruption.

Jackery also advertises this solar generator as a great option for camping, but at nearly 100 pounds, this isn’t the most portable power station. It does come with wheels and a handle for easier transportation, but that’s still a heavy weight to lift out of the car. The solar panels, on the other hand, weigh about 10 pounds each and fold for easy transportation.

 Jackery sells lighter solar generators, but they all have a lower capacity than the Explorer 3000 Pro. You may want to consider a balance between power and portability when shopping for a Jackery model for camping.

4. Goal Zero Yeti 6000x: Best capacity

Best Capacity

Amazon.com price as of post date. Read full disclaimer.

If you’re looking to balance power and price, the Goal Zero Yeti 6000x is a great choice. With a 6 kWh capacity, it can power more appliances and devices for longer periods than any other solar generator on our list, and it’s not even the most expensive option.

con
Cons
con Slow solar charging

The Goal Zero Yeti 6000x has one major drawback—a slow solar charge time. Even with four solar panels, it can take 35 to 70 hours to fully charge this generator. If you’re using only about a third of its power each day, then it may be sufficient to use in an emergency. Otherwise, it’s best suited for camping or short bursts of use.

5. Anker 555 Solar Generator: Best for basics

Best for basics

Amazon.com price as of post date. Read full disclaimer.

When you want something to get you through a power outage in comfort but don’t need it to fully power medical equipment or the fridge, try the Anker 555 Solar Generator. Its 1 kWh can power one fan for almost a full day. But, since it features six AC outlets and takes just six hours to charge, there’ll be power to spare for other creature comforts, like the internet router.

The Anker 555 is less useful for winter power outages because it only powers a small space heater (500W max.) for less than two hours. On the plus side, it can run a CPAP machine for over 18 hours on a single charge, allowing you to get a good (and safe) night’s sleep. 

This solar generator weighs nearly 30 pounds, comes with two solar panels, and features a built-in light - all of which makes it a great choice for camping too.

Final word

Because the EcoFlow Delta Pro Solar Generator recharges quickly and is capable of powering multiple appliances in your home, we think it’s the best solar generator for emergency use. To get the most out of it, purchase additional batteries and a full set of solar panels.

FAQ

The main disadvantage of solar generators is that it takes hours for them to recharge. Total charge time depends on weather conditions, your willingness to adjust the position of the panels throughout the day, and even your location on the globe.

Solar generators usually aren’t as loud as gas generators, but you may still hear some rumbling similar to the sound of a refrigerator.

You can do a little math to figure out if a generator’s watt-hour capacity meets your power needs. Watt-hours refer to the amount of Watts that it can power one hour. A kilowatt-hour (kWh) is one thousand watt-hours (Wh).

You’ll need to estimate which appliances or devices you want to power and how many watts they use in total. Then, you’ll need to divide the generator’s watt-hours by the total watts to determine how many hours the generator can power those appliances. Consider whether the appliances need to run continuously and how long it takes for the generator to reach a full charge to determine if the generator’s capacity is sufficient.

For example, let’s say you just want to power your 400 W fridge and you’re considering the 3.6 kWh EcoFlow Delta Pro solar generator. First, we can convert 3.6 kWh to 3,600 Wh (3.6 x 1,000). Then, we can divide 3,600 Wh by 400 watts to get 9 hours. In other words, the 3.6 kWh generator could power the 400 W fridge for 9 hours on a full charge.
