Why Backup and Battery Backup are Different

Often the terms battery backup and backup are used interchangeably. However, these two terms are not the same.

When used interchangeably these two terms can make reading about solar power confusing. Someone might think they are reading about one term and come to find later that it wasn’t what they thought it was.

Understanding what each of these terms means is the first step to making sense of this conundrum.

What is Back-up Power?

Back-up power is anything that will provide on-demand power. The term back-up power is often used to describe a source of energy for large facilities when the main source of power is down. 

Back-up power is often provided for hospitals with essential medical equipment and financial institutions with sensitive documents. When a power outage occurs, these institutions typically have back-up power within a few minutes of the outage.

It allows these businesses to continue running without having to worry about lost financial records or hospital patients dying. This type of power is also known as UPS.

UPS Backup

UPS stands for an uninterruptible power supply. Any device that can provide power during an outage is a form of UPS backup.

Home Backup Generator

One common form of back-up power is a gas generator. Gas generators are a common back-up power option because they are cheap initially and do the job. However, gas generators have flaws that make them inferior to battery backup

Battery Backup

Battery Backup is another back-up energy option. Battery backup is different because it stores power for later instead of generating it.

This form of backup is best suited for buildings or homes with solar panels because it can store the excess generated power for later use. Because of how solar panels work, a rechargeable battery’s ability to store electricity for on-demand use makes it so a solar array can provide a continuous source of electricity.

There are a couple of different battery backup options. The main battery backup choices for homeowners include portable power stations and home batteries. 

Portable Power Station

Portable power stations are smaller batteries that can provide power for homes that only need the essentials covered. Portable power stations are also a good option for home medical devices because they can easily move. 

Go Solar Group offers two different portable power station options in their battery backup product line up. The first is a Goal Zero Yeti, and the second is a Goal Zero yeti with expanded storage so it can power more for longer.  

 Home Battery Backup

Home battery backup is a battery or several batteries that power an entire home. These batteries can provide power for several days before they need recharging. This type of battery backup option is ideal for homeowners with larger energy demands or who value energy independence.

Why Battery Backup is Best for Residential Solar

While battery backup is a back-up option, not all back-up options are batteries. Homeowners typically choose either a gas generator or battery backup at their back-up option of choice.

The back-up power option to choose depends on the budget and situation it is for. Solar homeowners often choose battery backup because they can store energy instead of requiring a secondary fuel to power it.

This option also allows homeowners with solar to decrease their carbon footprint.
