A DC generator is Direct Current most common in industrial environments.Limited to DC equipment such as motors, cranes, certain types of lighting etc.A AC generator is Alternating Current can be used...
Converting D/C into A/C is very expensive. You can use inverters to switch the direction of the current but you would probably be better off to replace your DC generator with an AC generator and if...
