To use a stabilizer to generator to home appliance depend on
two condition.
If it is single
home small generator or common portable generator use for a
personal home use, then there is not need of using a stabilizer to your
generators, most of these generators come with a fixed voltage of 220v you
don’t need to stabilize anything.
The only thing I will
suggest you do is to switch on more
appliances if you observe that the power
if so much for the load or to switch of some appliance if you observe that the load is too much for the load.
In case of a large
KVA generator or community generator you
will need a stabilizer to staiize the the voltage.
This large generator
has no difference with normal mains supply.
You will need a stabilizer
to either step up or step down the voltage to your desired voltage.
When you are using a
community generators other people are also tapping their power from te same source
the voltage may be will be lower and some high energy consuming appliance like
refrigerator cannot work . therefore you need a stabilizer.
As I said before, a
small home portable generator with low
power rating do not need a
stabilizer, the power they supply is
usually lower an do not need a a voltage
regulator.
Using a stabilizer on
this type of generator is dangerous and should be avoided at all cost, most stabilizers draws more
electric power and if you allow them on
you small low KVA generator it will simply spoil the generator.
Stabilizers are not
made for small generators as their power rating is within home use, I will
suggest you switch off some appliance when you observe low voltage or witch on
some appliance when you observe high voltage.
