Best Standby Solar Generators For Home Use

6 Best Backup and Standby Solar Generators 2019: Reviews & Buying Guide

Whether you are looking for a viable "off the grid" living option or want a backup power supply in the event of total power loss, solar generators offer a green solution that can be just as effective as gas and propane generators.

Backup power for the home is important and is a must-have as more and more of us rely on connected devices, phones and laptops.

Solar backup generators are not just for powering home appliances like refrigerators and air conditioning - more and more, they are being purchased to provide reliable backup power for critical medical devices.

For example, CPAPs are a popular way to treat sleep apnea and other dangerous sleep disorders. Without an adequate supply of power, things can get dangerous - fast.

The Problem With Gas Generators

Gas, diesel and propane generators have been relied upon for years for home power backup and emergency standby power for everything from hospitals to homes.  The are relatively cheap, easy to maintain and widely available.

That said, gas generators suffer from a number of important drawbacks. 

Fuel Supply

A gas generator doesn't store electrical energy. Instead, it converts fuel into electrical energy when you start it up.

To keep the lights on, then, you must constantly resupply a gas, diesel or propane generator with fossil fuel.  Doing so costs money to buy the fuel, unlike solar power which is free.

And what happens if your fuel supply runs out?  For some people, running out of fuel is more than just a lights-off annoyance - it can mean the difference between life and death.

In contrast, solar generators run on the power of the sun, which is 100% renewable, free and reliable. 

Home Solar Generator


is another issue with gas and propane generators: most are really loud when they run. Solar generators are completely silent.

Exhaust & Emissions

Burning fossil fuels emits toxic gases such as CO2 and carbon monoxide.

This is why you have to run a gas generator outside. Don't even think about using a fossil-fueled generator in an enclosed space – if the noise doesn’t drive you crazy, the CO2 and carbon monoxide emissions can kill you.  

Exhaust and emissions are not a problem with a solar generator. You can even run one on your kitchen counter.

The Best 6 Backup/Standby Solar Generators

Solar generators offer a greener, renewable and more reliable solution to all of these problems.

Solar generators are quiet, lack any harmful fumes and exhaust, and are completely renewable. With a handful of well-placed solar panels, you can provide a FREE supply of backup power for your home.

Today, solar home backup power is within easy reach of anyone.

Over the past few decades, the steady march of technology has extended battery life and  made solar panels less expensive and more efficient.

As a result, solar generators have gone from a wildly expensive, fringe DIY project, to a user-friendly and affordable solution that anyone can purchase online.

The cost of a solar generator remains higher than a comparable wattage power gas generator, but considering all of the benefits, a lot of people today are choosing to go solar.

Today, you can select from dozens of solar generators designed for home power and standby backup.

Which ones stand above the rest?

Read on to learn about 6 of the most popular retail solar generators sold today.

NOTE: In addition to the retail generators listed on this page, you can find more expensive, permanently installed generator solutions from any licensed solar energy installer in your town.

What You Need to Know About Backup Solar Generators

The solar generators on this page can be bought online and are designed for powering home appliances and lighting and for recharging vital electronics.  

That said, there are limitations and other things you need to be aware of when shopping for a home solar generator.

Very Few Solar Generators Can Power Every Appliance In Your Home

Some heavy appliances like clothes dryers, water heaters and pool pumps consume a huge amount of energy that will sap any generator - solar powered, or not.  In general, a single solar generator won't power heavy appliances and devices for very long.

Mid-range appliances like air conditioners, freezers and electric ovens are far more energy-efficient today than a few decades ago. Most backup solar generators can power these for a single use between charges, but not much more.  

The sweet spot for solar backup generators is powering small appliances like LED televisions, toasters, and hair dryers. And, of course, keeping your electronics on and recharged.

Standby Home Solar Generator

Because of this wide gulf in power consumption among home appliances, you need to have realistic expectations when shopping for backup and standby solar generators.

The most powerful home solar generators are capable of keeping your refrigerator on, keeping your computer and electronics running, and powering a handful of lights and other appliances, but they are not yet able to match the full-home power supply of larger backup generators powered by natural gas and propane.

Still, solar generators are very useful backup power supplies in the case of a home blackout, because they offer so many advantages.

To make the right solar generator purchase, you'll want to have an idea of the required voltage and total wattage of the devices & appliances you want to keep alive during a blackout.

Use our handy appliance wattage guide to figure out how many watts you'll need to keep your most important lights, devices and appliances running

Then, look for solar generators that supply that level of wattage.  And make sure they have the right type & number of outlets (12V, 110V, 220V, USB, 2A, etc.)

If you are really committed to buying a completely renewable backup generator for your home and want enough backup/standby power to run your air conditioner and refrigerator for days, then you can always purchase multiple generators.

Some of the units below, like the GoalZero Yeti 1250, can be be chained together to supply more power.

The Best Solar Generators for Home Backup/Standby Power

Goal Zero Yeti 1250 Solar Generator

GoalZero is the most popular solar generator manufacturer today. Goal Zero's Yeti 1250 is the most powerful generator they offer. The Yeti 1250 is an effective backup home generator capable of powering several high-wattage appliances and devices at a time.  It can also be chained together to handle whole-home demands.


The Yeti 1250 is loaded with user-friendly features that keep it simple and efficient.

Goal Zero Yeti 1250 Solar Generetor In Garden

First and foremost, this solar generator is really powerful for its size. The battery has a capacity of 1200wh and 100 amp hours, strong enough to power several laptops and a small energy-efficient refrigerator.

The lead-acid battery in the Yeti 1250 lasts hundreds of recharge cycles and should last for many years.

This generator is chainable, so you can hook up multiple units to supply true whole-home power.

The Yeti 1250 has multiple outlet ports to power several devices and appliances at once, including 3 USB ports, a 12V port, and 3 AC ports. If you need to transport the unit, a cart is included with a collapsible luggage-like handle.

The Yeti 1250 is chargeable via solar panels, and can be recharged using AC and 12v power sources when the sun isn't available. 

The LCD monitor display screen on the Yeti 1250 helps you accurately keep track of the battery's current charge, remaining charge time and rate of power consumption.

Keeping The Vitals On

The Yeti 1250's power output and fast charge time makes it a great backup generator to plug into during power outages.

The unit is powerful enough to keep a handful of vital appliances running for several hours, while providing numerous recharges to handheld devices and laptops.

Goal Zero Yeti 1250 Solar Generator

This generator will keep the lights on, one television going, and the refrigerator running for many hours during emergencies.

Although the generator is a home backup, it is also portable, so it can be used for construction, workshops, and camping if you're willing to haul it around.


This generator isn't as powerful as some of its home backup/standby rivals. 

The Yeti's lead-acid battery can be a turn off for those wanting a lithium battery, which not only has a longer lifespan, but is much lighter as well.

The Yeti 1250 is also heavy - it weighs just over 100 lbs.


The Yeti 1250 is an affordable and user-friendly home power backup solution that will keep your critical appliances on and your electronic devices charged during any emergency.

Just don't expect it to power your entire home, unless you chain a few together.

Be Prepared Solar 2500 Watt 200Ah Solar Generator w/ Two 150 Watt Solar Panels

This generator from Be Prepared Solar is a powerful, no-frills home backup or off-grid solar generator that can power several high-wattage appliances.

It's also designed for portability, so it's great for long camping trips and for off-grid living.


What this generator lacks in features, it makes up for in power. This solar generator can supply a whopping 2500 Watts of peak power.  

It is recharged using two 150 watt solar panels that have a 25 year warranty.

The generator is contained in a simple snap-lid plastic case that has two wheels and a front handle for easy transport.

Be Prepared Solar Generator

The case measures 32 x 18 x 18 inches, and weighs just 35 lbs, so moving it around shouldn't present much of a hassle compared to other backup units.

Five total outlets are included with this model: 2 AC outlets are located outside, along with a USB outlet. Two more AC outlets are inside the unit. Although two solar panels are included, you can add more for a faster charge time.

This particular generator is suitable for home backup, but it can also be used for backup power and additional power for RV's and campers.

A charge controller is included for keeping the battery from overcharging.

Simple, Affordable, Abundant Power

This generator is designed to provide the maximum amount of wattage in the smallest and simplest package.

Smaller items like laptops, television, and phones can be powered and recharged numerous times during the duration of the generator's charge. Lighting will stay on all night if needed.


While it's certainly powerful enough to power 2500W (5000W peak) worth of appliances, doing so will run the battery down pretty fast, so items such as refrigerators, portable heaters and freezers should be connected on an intermittent basis.

As you may notice, this isn't the most user-friendly generator. There are no screens indicating power usage, and the unit arrives unassembled, so you'll need to put it together yourself.

Also, you will need to assemble this unit when it arrives, but it's painless.​

Be Prepared Solar 5000 Watt 200Ah Solar Generator

The case is not very aesthetically pleasing, either, and hauling the unit around can be a bit awkward.


Despite its drawbacks, this generator is the definition of a home standby generator, delivering a lot more power than most generators in its price range.

If you have a basic knowledge of electricity and don't mind assembling your generator, then you'll definitely appreciate the value for money.

Humless L-1500 Connected To Car

The generator features two modes: pass-through and normal. Pass-through mode allows the current to bypass the generator and feed straight into the device(s) plugged into it, whereas normal mode allows for the unit to charge without powering anything else.

The unit also features a snap-lid compartment on the top for easy storage of accessory cables.

Solar Power At Home Or On-the-Go

The 1200W capacity of this generator makes it capable of partial backup and standby use, and the size and weight makes it just as easy to grab and go for use on the road or at a campsite.

Unlike some other generators, the design and layout of the generator is anything but intimidating, and allows for anyone to use it in confidence.

Easy and efficient charging via the included panels makes the unit sufficient for repeated use during extended blackouts and outages.

The wattage makes the generator capable of supporting mid-range appliances such as mini-fridges and flat-screen television for several hours at a time.


The Enerplex 1230 is powerful, but the useful wattage does falls short of most home backup generators. The unit's screen could use an upgrade as well.

Enerplex Generatr 1200E Portable Lithium-Ion Battery Generator


If you are looking for a backup home generator that is also portable enough to power a campsite or your boat, the 35-pound Enerplex is a great choice.  

This package can be hard to find these days.  If you can't find one for sale online, then a good alternative is the GoalZero 1250.​
