Best Standby Solar Generators For Home Use

Best Home Backup Standby Solar Generators 2019

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.  They are cheap, easy to maintain and widely available.

That said, gas generators suffer from a number of important drawbacks that solar generators completely avoid - as follows:

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 when 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. 

Noise

Loud noise is another issue with gas & propane generators. Most are really loud when they run.

In contrast, 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 could kill you.  

Exhaust and emissions are no problem with a solar generator, however -  you can even run one on your kitchen counter.

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

Standby Home Solar Generator

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.

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.

How to Choose the Best Solar Powered Generator

Solar Generator

Things to Consider when Choosing a Solar Powered Generator

1. Solar panel output 

The first thing to consider is your PV (photovoltaic) output. That’s the amount of power your solar panels generate.

You need to make sure that the voltage and amps are within the limit of what the battery can handle.

You also need to check that your solar panels can charge the batteries quickly enough.

If it takes days to fill up your battery, your solar generator won’t be of much help, especially if you rely on it often.

If you want a powerful solar powered generator, get high-wattage solar panels as well.

But if you want a smaller standby generator to charge small devices like smartphones, a basic 100-watt solar panel will do.

2. Battery Capacity and Type

Battery capacity is expressed in amp-hours (Ah) or watt-hours(Wh).

Generally, for most applications, you want a solar generator with a battery capacity of at least 1,000 watt-hours.

This lets you power small gadgets as well as some appliances.

You can go lower to around 600-800Wh if you are only charging your smartphone or laptop.

But if you want something that can power a fridge or mini AC, look for a 2,000+ watt-hour generator.

A higher battery capacity not only lets you power more gadgets and appliances, but it also provides backup power for longer at night and in bad weather.

Note: The Wh rating of a battery is not its actual usable capacity. With most lead-acid batteries, you should discharge no more than two-thirds of the battery. So a 1,000Wh battery has a usable capacity of around 666Wh. Keep this in mind when selecting the right capacity for your needs.

It’s a good idea to get a bigger battery than you need.

As you consider what battery capacity suits your needs, also think about the type of battery.

Most solar generators use sealed lead acid batteries. They are inexpensive; they last relatively long and are reliable.

Solar generators with lithium batteries are more expensive. But they provide more power, higher charging efficiency, and a longer lifespan.

3. Inverter Rating 

Capacity doesn't tell you everything you need to know about the battery’s capability.

In addition to how much charge it can store, you also need to know how much power you can draw from it.

This determines what kind of gadgets and appliances you can power.

The inverter rating tells you how much power the battery can produce at any given moment. It’s given in watts.

The inverter is the part that converts DC power from the battery to the AC power you use to power appliances.

For small appliances and gadgets, a 1,000W-1,500W inverter is good enough.

For bigger appliances, look for a solar generator with an inverter rating closer to 2000W or higher.

Remember also to check the peak or surge rating. This is the maximum amount of power the battery can supply for a limited time, typically a few seconds.

Some appliances such as refrigerators and pumps require more power during startup.

In most solar generators, the surge rating is double the standard/continuous power rating. But check the specs to be sure.

4. Type of Inverter 

Don’t just check the inverter rating; also check what kind of inverter it is.

There are three types: pure sine wave, modified sine wave, and square wave inverters.

I won’t bore you with the technical explanation behind each type. Here’s all you need to know.

Pure sine wave inverters are the best but also the most expensive. They are more efficient, and most appliances work best and at full power when connected to a pure sine wave inverter.

Some timers, lights, and digital clocks will not work properly unless connected to a pure sine wave inverter.

Square sine wave inverters are the cheapest and the least efficient. They can only run basic appliances with universal motors. You are unlikely to find a solar generator with a square sine wave inverter.

Modified sine wave inverters fall somewhere between the above two types of inverters, though they are much closer to the square ones.

While modified sine wave inverters will power most appliances and gadgets, they are less efficient and can cause some devices to malfunction.

On the upside, a modified sine wave inverter is cheaper than a pure one.

But if you want a powerful and efficient solar generator, look for one with a pure sine wave inverter. The extra cost is worth it.

5. Output Options 

This is something many people forget to check when buying a solar generator only to discover they cannot plug in their fridge or charge their phone.

A good solar generator should have three output options: an AC outlet, a 12V DC outlet, and USB ports.

The number of each type of output varies. Some generators can have as many as 4 USB ports, maybe a couple of AC outlets and one 12V socket.

6. Portability 

Most standby solar generators require a degree of portability. This makes it easy to use them at the point of need, whether it’s in a specific room, outdoors or out in the wild.

Portability is also important in solar tracking, where you move the solar generator and panels to maximize sun exposure.

The lightest standby solar generators weigh about 30-40lbs. These are relatively easy to move around, albeit with some help.

Powerful generators can weigh close to 100lbs. Many come in heavy-duty casings with wheels for easier portability.

If your chosen solar generator doesn’t have wheels or is hard to move, consider buying a cart.

7. Extra Features 

Here are some additional features to look for.

Multiple recharge options: A solar generator you can recharge from a home wall outlet or out of your car’s cigarette lighter socket can be useful at night or in bad weather. Additional recharge options are also handy when you need to quickly recharge the battery (solar panels can take several hours or days to fill up the battery).

Stackable: Check whether you can connect multiple batteries for extra capacity. Some solar generators even come with ports you can use to daisy-chain several batteries.

LCD display: An LCD display lets you monitor how much power the solar panels are producing and how much charge you have left in the battery.

Fast charging USB ports: The USB ports found in most solar generators are the standard types. Some generators come with fast-charging USB ports that juice up your devices in less time. This is especially handy if you want to charge multiple devices.

Wireless connectivity: A solar generator with WiFi or Bluetooth connectivity allows you to monitor power consumption and PV input easily on your Smartphone. But with Bluetooth, you need to be in range. If the generator uses WiFi, you can monitor the system from anywhere.


Things to Avoid when Choosing a Solar Powered Generator

best solar generator

Here’s what to avoid when shopping for a solar generator.

1. Square-Sine Wave Inverters 

We’ve already discussed the three types of inverters.

Avoid square sine wave inverters; it unlikely you’ll find them anyway.

2. Very Low Capacity Solar Generators

Even if you are charging gadgets like your smartphone, tablet, and camera, it’s still a good idea to get a decently sized solar generator.

Don’t go below 600Wh.

If you plan to power an appliance like a CPAP machine, a coffee maker or a fan, don’t go below 1,000Wh.

You want a generator that can last at least a full day and night even on cloudy days.

3. Very Low-wattage Solar Panels 

The solar panels that come with some generators feel like tokens rather than a genuine effort to provide customers with a complete system.

A 50W solar panel will take days to charge a 100Ah battery.

Check that the solar generator comes with solar panels that can charge the battery in at most 6-8 hours.

One 100W panel or two 50W panels are good enough for most standby solar generators.

4. Low Quality or Suspiciously Cheap Solar Generators 

‘You get what you pay for’ holds up well when it comes to buying a solar generator.

Despite the potential savings, you are better off avoiding cheap off-brand solar generators, especially if they boast a high wattage and capacity.

Buy from a trusted brand with a reputation for high-quality products.


Setup of a Solar Powered Generator

set up solar generator

Installing an Off-Grid Solar Generator System

If you are going off-grid whether it’s camping, boating or living in a cabin somewhere in the woods, it’s essential that you harvest enough solar energy to meet your needs.

Solar Panels 

The first thing is to make sure you have the right number and capacity of solar panels. Your solar array should fill up your battery with a day’s worth of sunshine (at least 6 hours).

Monocrystalline solar panels are the best though they can be a bit pricey. If you are on a budget Polycrystalline will do.

Set up the solar panels where they will receive maximum exposure.

If it’s an off-grid house, roof mounting is the best. For RVs and camping, use a solar panel ground mount that you can move around to keep up with the sun’s position.

If possible, the solar panels should face south at an angle of about 30 degrees.

Charge Controller 

Most standby solar generators come with the charge controller built in or included separate from the main unit. So you don’t need to worry about buying a charge controller.

If your generator doesn’t have a charge controller, look for one that is rated for your solar array’s total output voltage and current.

It should also be compatible with your battery’s voltage.

Battery 

The battery will also be integrated into the solar generator. It can be lead acid or lithium.

As I mentioned, a high ampere-hour or watt-hour battery lets you power more stuff for longer.

Inverter 

As with other components, there is no setup for the inverter. It’s integrated into the system.

You need to remember to turn it on when using the AC socket. This converts the DC power from the battery into usable AC power.

Installing an On-Grid Solar Generator System

For on-grid homes, you need to install the solar panels on the roof or ground, connect them to an inverter than connect the invert to your mains.

The inverter converts DC power from the solar panels to AC power that is compatible with your home electrical system.

Your home will use free solar energy during the day and seamlessly switch to grid power at night or when it’s cloudy.

If you don’t want a whole house backup system, you don’t have to do all this.

You can connect your solar panels to the solar generator. Then when utility power goes out, you can plug in your essential appliances and devices into the solar generator.
