Backup power systems, like generators, are great to have around the home, but what use are they for keeping your entire home powered up? Large-scale appliances require a tremendous amount of energy, and it can be difficult to find a device strong enough to keep your home running without interruptions.
If you’ve been searching for a split-phase power source that can power your 120V and 240V appliances and runs sustainably, the EcoFlow DELTA Pro 3 is the answer. Read on to learn how this device works and why it is an excellent investment for your home.
What Is Split-phase Power, and Why Does It Matter?
For starters, it’s essential to understand your power needs. The majority of homes in the US function on an electrical system known as split-phase power. Split-phase power, as opposed to single-phase power, is designed to power both 120V and 240V appliances, making it more efficient and practical for the typical American household.
These electrical systems function by having two live wires. When used on their own, they can supply 120V of power. When used together, on the other hand, they can provide double that and can then supply power to large-scale appliances for extended periods of use.
The split-phase system is essential in the household and allows for a seamless and efficient electrical solution to power large and small appliances.

When Do You Need 240V Split-phase Power?
Small-scale devices and appliances, like your coffee maker or laptop, can run under a single-phase electrical system with no issues. Larger appliances, however, require a larger energy output to work.
Want to understand what exactly a split-phase electric system is used for in your home? Here’s a quick breakdown of some of the more common use cases of this 240V power system.
Electric Dryer
Split-phase power helps your dryer run by supplying enough power for the motor and heating elements to work in unison. Without the consistent stream of 240V, this appliance cannot function.
Central AC Unit
A central AC unit requires a lot of power to keep your home comfortable throughout the year. The split-phase electric system is designed to keep this unit running without risking overworking and ultimately damaging it.
Water Heater
Hot water access throughout the house is a vital resource that many people rely on daily. Split-phase systems are necessary to provide enough energy to maintain large quantities of hot water throughout the day.
