We know that
Inverter is an essential component of nearly all types of solar photovoltaic
system; it is defined as the device that converts DC electricity to AC
electricity.
Now I will
introduce to you all types of solar photovoltaic Inverters present at the
market:
First: Stand Alone Solar Inverter, which characterize by the following:
1-
It coverts DC electricity to AC electricity.
2-
It runs by pulling DC current from batteries charged from any DC
electricity source like engine generator or wind turbine …etc.
3-
In the same time it refill batteries with DC electricity from any AC
current Source when it possible.
4-
It used in feeding homes and small industrial system by AC electricity
as a power backup.
In most cases as conclusion we use it in stand
alone solar photovoltaic system with backup.
Second:
Battery Backup Solar Inverter, which characterize
by the following:
1-
It used to get AC electricity from batteries and this AC electricity
will go to a selected area which needs power during outage and in the same it
brings extra electricity to utility grid "feed in tariff ".
2-
It contain onboard charger to manage the batteries energy.
In most cases as conclusion we use it in stand
alone solar photovoltaic system without backup.
Third:
Grid Connected Solar Inverter, which characterize
by the following:
1-
It used to convert DC electricity to AC electricity and it is programmed
to automatically turn off during grid power outage.
2-
It allows the home owner to sell electricity to Electricity Company.
In most cases as conclusion we use it in grid
connected photovoltaic system without battery backup.
Fourth:
Micro Inverter, which characterize by the
following:
1-
It attaches directly to individual photovoltaic modules.
2-
It is used to extracting maximum electrical power from each module.
3-
Although it is highly efficient as it produces more electrical power than
on grid inverter but it is more costly.
Really thanks for sharing this useful post about Solar Photovoltaic Inverters. Keep posting informative content regarding solar system .
