What is Power Inverter and what does that used for

A power inverter is a power electronic equipment that changes Direct Current (DC) to Alternating Current (AC)
The input voltage, output voltage and frequency, and overall power capacity depend on the design of the specific device or circuitry. The inverter does not produce any power, and the power is provided by the DC sources.
A power inverter can be entirely electronic or may be a combination of mechanical effects (such as a rotary apparatus) and electronic circuitry. Static Inverters do not use moving parts in the conversion process, ACSOON Power engaged in the design and manufacture of Static Inverters many years.
Power inverters are primarily used in electrical power applications where currents and voltages are present
ACSOON® ANDW series power supply single units are available with the following capacities:
Single phase output: 500VA ~ 10KVA
Three phase output: 500VA ~ 100KVA

Input

A typical power inverter device or circuit requires a relatively stable DC power source capable of supplying enough current for the intended power demands of the system. The input voltage depends on the design and purpose of the inverter. Examples include:
24, 36 and 48 V DC, which are common standards for home energy systems.
110V and 220VDC, which are common standards for Industrial or Commercial power systems
200 to 400 V DC, when power is from Photovoltaic solar panels.
300 to 500 V DC, when power is from electric vehicle battery packs in vehicle-to-grid systems.
