Inverters

The frequency inverters use for control the motors and the DC/AC invertes using for convert the DC voltage to AC voltage. 

Inverters convert DC electricity into AC electricity. Solar panels (and most small wind turbines) produce DC electricity. That electricity is used to charge a battery bank in off-grid systems or sent directly to an grid tie inverter which feeds the electricity directly to the electric grid. We offer some inverters which are capable of both working as an Off-Grid and an On-grid inverter.

Hybrid Inverters 
These inverters are primarily used for grid-tie purposes but also have the added feature that they provide backup power to your home / office when the electric utility fails. 

Off-Grid Inverters 
These inverters are principally meant to be used with solar for a home or business totally disconnected from the electric utility company. They can also be used for providing emergency backup power to homes that currently use the power from an electric company. Inverters with the built-in AC charger option are particularly well suited to providing seamless backup power. 

Grid-Tie Inverters 
Inverters which are connected to your electric utility company and do not use a battery bank. These "grid-tie" systems tend to be lower in cost due to the fact that they don't use batteries. However, if the utility company's power goes down then your system will also shut down. If blackouts are frequent in your location or you want to have backup power, consider purchasing an inverter that is Hybrid.

A devise used to convert direct current into alternating current.

Inverter - It is used for saving a power in battery. Inverter are very useful for tamilnadu especially chennai.

In terms of electrical power, an inverter converts direct current (DC - as in batteries) to alternating current (AC - as in what is present at electrical outlets). 

An inverter would be used in a car, for example, to run an AC-powered "appliance" (laptop computer for example) in the absence of an AC outlet.
