Usually, for single phase generator, it is normally for
residential use. However, three phase generator is primarily for industrial
use.
If
you are looking for a generator to power larger, commercial businesses, you’ll
likely want to invest in a three-phase generator, which have a typical voltage
of 480. Many large pieces of equipment and electric motors, as well as data
centers and industrial areas, will require the power that you can get out of a
three-phase generator. While these generators generally cost a bit more than
single-phase generators and can require more maintenance, their reliability and
unbeatable efficiency can keep larger operations functioning in tip-top shape,
at all times.
If you are looking for a
generator for a rural area, you can choose single phase generator, small
equipment don’t require
constant, high-voltage power, single-phase used generators provide an efficient
source at a lower cost. Most single-phase generators operate anywhere from 120
to 240 volts..
Three-phase
generators are ideal for heavy duty
industrial, agricultural, commercial, and professional applications that
require intensive, constant power. a three-phase portable generator will help
you get the most trying tasks completed with efficient, constant, and safe
power.
Characteristics of three phase generator
1) Increasingly
popular in power-hungry, high-density data centers
2) Expensive to convert from an existing single phase installation, but 3-phase allows 3) for smaller, less expensive wiring and lower voltages, making it safer and less expensive to run
4) Highly efficient for equipment designed to run on 3-phase

In generator, a three phase ac generator has three single phase windings spaced so that the voltage induced in each winding is 120° out of phase with the voltages in the other two windings.
Working principle
Single-phase
generators produce one single voltage that alternates continuously. Because the
power is generated in one single wave, the level varies throughout its cycle.
These varying waves cause the power level to drop throughout the process,
however, these drops generally go undetected to the eye and ear in normal,
residential and smaller operations.
Three-phase
generators work by producing three separate waves of AC power that operate in a
sequence, ensuring that there is always a continuous flow of energy and that
the power level never dips as it does with single-phase generators. Because of
this uninterrupted reliability, three-phase generators are much more powerful.
Difference
Between Single Phase & Three Phase
Single-phase and
three-phase generators provide power differently. The most obvious evidence of
this is seen in power delivery. Both types provide AC power, but a three-phase
system produces three separate waves of power, delivered in sequence. This ensures
a continuous uninterrupted flow of power that never drops to zero and makes
three-phase generators more powerful than single-phase generators.
3-phase systems are
ideal for high-capacity settings which is why you usually only see them in
industrial and commercial areas. Data centers, in particular, benefit from
3-phase backup generators due to the increased distribution capacity. 3-phase
systems can power multiple racks whereas single-phase systems cannot.
