Most power inverters are designed to convert 12-volt, 24-volt, or 48-volt DC to 120-volt AC. These inverters are commonly used in recreation vehicles and solar power systems. Special inverters can be connected together to produce 220-volts. This process is called stacking. This process cannot be used for any type of power inverter. The inverter has to be specifically designed to allow stacking. Using this process with an inverter that is not designed for stacking will destroy the power inverter. Writer Bio
