The main applications of inverters in the field of communication

The main applications of inverters in the field of communication are:
Provide AC auxiliary power supply for DC power supply.
Some maintenance tools require AC power supply, but DC power cannot provide AC power supply, which can be provided through inverters.
Provide DC-AC conversion function for photovoltaic grid connected power system.
Invert the direct current generated by the solar system into alternating current and input it into the power grid.
