A power inverter, or inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC)
The input voltage, output voltage and frequency, and overall power handling, are dependent on the design of the specific device or circuitry.
Typical applications for power inverters include:
Portable consumer devices that allow the user to connect a battery, or set of batteries, to the device to produce AC power to run various electrical items such as lights, televisions, kitchen appliances, and power tools.
Use in power generation systems such as electric utility companies or solar generating systems to convert DC power to AC power.
Use within any larger electronic system where an engineering need exists for deriving an AC source from a DC source.
These inverters are combination of Solar inverter, ups and Charge controllers. These inverters can operate of 3 way input WAPDA, Solar and Batteries. While operating on WAPDA or Solar panels these systems can also charge battery bank for backup use.
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.
