The inverter can convert the DC power of the battery into AC output. Of course, various DC outputs can be added as needed, and various protection functions can be added through the controller to control input and output.

[0035] A generator set primarily consists of an engine, a generator, and an electronic control system. Driven by the engine, the generator outputs electrical energy, converting the chemical energy of fuel or gas into electrical energy. Digital generators also include an inverter, which converts the medium-frequency AC power output of the generator into stable industrial-frequency AC power at various speeds.

[0036] Solar photovoltaic power stations use solar panels to convert solar energy into electricity. Inverters and electronic control systems convert the DC power from the panels or batteries into AC output. Electric welders primarily consist of a transformer and an electronic control system. The transformer steps down the AC / DC power from the mains, generator, or battery. After processing through the electronic control system, the transformer outputs low-voltage, high-current AC and / or DC power, which melts metal materials for welding.
