Do you know how to choose between a UPS three phase system and a UPS single phase system? Do you know the difference between them? This article will help you understand UPS three phase and UPS single phase, and distinguish them clearly!


When your organization needs to purchase a UPS, you need to consider whether a UPS single phase or three phase system is more in line with actual needs. Although both UPS systems can be used as backup power systems, there is still a big difference between them!

1. Cable-UPS single phase vs three phase

The number of cables differs in single phase and three phase systems.
Single phase UPS systems provide power to loads at AC 110V/220V/230V through 3-wire cables (Live, Neutral, and Earth).
Three phase UPS system provides power to the load at AC 380V or 400V through a 5-wire cable (L1, L2, L3, Neutral and Earth).

The standard voltage of the system is different in different countries or regions.


2. Sine wave-UPS single phase vs three phase
A single-phase UPS system provides a single sine wave, while a three-phase UPS system provides three sine waves, each out of phase and 120° apart from each other.


3. Maintenance-UPS single phase vs three phase
Compared with three-phase UPS systems, single-phase UPS systems are easier to install and easier to set up!


4. Efficiency-single phase vs 3 phase UPS
In terms of low power, single-phase UPS systems are more efficient than three-phase UPS systems. But when the power demand is higher, the three-phase UPS system shows higher efficiency and can carry larger loads in a safer manner.


5. Cost-single phase vs 3 phase UPS
Three-phase UPS systems have a longer life expectancy, and the transmission lines for three-phase power do not require thick copper wires like single-phase UPS systems, so three-phase UPS systems will save more money in the long run.


6. Application-single phase vs 3 phase UPS

Three-phase UPS systems are commonly used in larger installations such as most large enterprises, medical centers, and high-density data centers, as well as larger industrial power applications with higher power requirements to allow large industrial equipment to operate more efficiently.

Single-phase UPS systems that power everyday equipment such as laptops, lighting, and televisions. Wide range of applications, used in most homes and small businesses, but most efficient for appliances up to 1000 watts


How to choose single phase vs 3 phase UPS?

Choosing between a single-phase UPS system or a three-phase UPS system depends on the power requirements of your application and the power source your equipment is connected to. You need to identify the load the UPS will protect and verify its voltage range.

Now I recommend you the three-phase inverter system of Xindun Power, which can output both three-phase power and single-phase power, which can meet the power needs of various small and large application scenarios! Our three-phase inverters support the power range of 4KVA-200KVA. We can provide three-phase inverters with different appearances and sizes, and our three-phase inverters can provide power normally when off-grid. Use solar energy, mains power, or generators to store power for the battery. When the grid power is cut off, the device can still work normally without losing the original data! It can be described as a powerful uninterruptible power supply system!


As a manufacturer with strong technology, Xindun Power has maintained the innovative development of inverter technology for more than 16 years. 
Please get in touch with us if you have any questions concerning the technology or cost of three-phase inverters. And we aim to strengthen our partnership with you in order to jointly grow the inverter market throughout the world. Make full use of renewable energy to develop and strengthen yourself.
