What is a Backup Generator for the Home?

A backup generator, or home standby generator, is a system that is usually installed permanently outside the home. It switches on automatically whenever there’s a power cut, even when you’re out of the house. One can run for long periods using a fuel supply from your home, using either natural gas or liquid propane.

How Does a Standby Generator Work?

When a blackout happens, a standby generator will automatically switch on and use a transfer switch to swap over energy from your utility to the backup generator. By using fuel, the generator can produce electricity for the home. Once the blackout subsides, the backup generator will switch back the home power supply from the generator to the home utility, returning to standby mode.

7 Reasons Why You Might Need an Alternative to a Back Up Generator

A solar generator is a fantastic alternative to a gas generator. Here are some reasons why it’s a good idea to consider a solar generator option instead.


The only way to power up a static backup generator is via a home gas supply. EcoFlow is changing the game by teaming up solar panels with portable power stations. Get clean, green energy from the sun that is easily accessible. This is especially poignant in 2022 with gas shortages and price spikes across the globe.

Finding Space can be an Issue

Not everyone has space for a home standby generator. Some people live in condos with barely any outdoor space on their balcony. Luckily, with an EcoFlow solar power generator for home use, you can store it indoors and open up your solar panels ready to collect that sought-after solar energy.


Perhaps you’re looking for a backup generator that you can use indoors. Maybe you’re wanting one more compact that you can put on a kitchen countertop. Or maybe you would like the option to take it with you for weekend breaks away. EcoFlow has a range of solar generators in different sizes and capacities to suit your needs. With old-school generators, this just isn’t possible.

Easy to Use

Standby generators can be intimidating and difficult to set up. Thankfully, EcoFlow’s plug-in-and-go solar generators are simple to use and don’t require any professional wiring. You can literally just plug in as you would at your wall socket and use your appliance indoors or out.

Cut Back on Energy Bills, Stay Secure

With a standby generator, gas bills have to be considered. When there are shortages, prices can skyrocket. In extreme emergencies, fuel might even be hard to come by. EcoFlow solar generators on the other hand can be powered by the sun, giving you another source to rely on. It also helps you to lower energy bills.

Expandable Capacity

The capacity of a traditional backup generator for home can’t be expanded. What you buy is what you get. You then rely on how much fuel to guzzle. On the the hand, all EcoFlow solar generators can be expanded with the EcoFlow Ecosystem for a fully equipped home setup. That’s extra batteries, extra solar panels, or even add-on portable AC units in the form of EcoFlow Wave.


While standby back up generators are static, EcoFlow solar generators can be carried around wherever needed. You can even pack one away in the trunk of your car to take with you off-grid.

What if there’s no sun?

While it’s called a solar generator, you don’t have to rely on the sun to charge it. EcoFlow Solar Generators can be charged by a ton of methods. Plain old wall outlets work fine and fast, your car outlet while on the go, or even with a traditional gas generator when you’re all out of other options.

Why a Solar Generator is the Best Alternative

A solar generator for home use is more flexible and the most eco-friendly way to provide power to your home whenever there’s a blackout. If your area is prone to power cuts due to weather extremes, frequent roadworks, or animal interactions, you’ll be safe in the knowledge that your own collected power – whether from a solar or ac outlet – is stored away in a system ready to use.

Besides, you’re also doing your bit for the planet by getting your solar supply from the sun and cutting back on your fossil fuel usage.
