Here are the key principles behind the operation of a 48V to 120V inverter: DC to AC Conversion: The inverter takes the DC power from the battery and uses electronic circuitry to convert it into AC power. Pulse Width Modulation (PWM): The inverter uses a PWM technique to replicate the sine wave of AC power.The tranformer that is there is a 460 primary to 120/240 secondary. Oh, so the main service is 480. Doesn't sound like it would be a problem, although its more common to stick with equipment that works with the available voltage. A lot of equipment will work with either 208 or 240 volts.

To clarify 120V/240V is single phase, not dual phase. Electronically it is like a 240v center tapped transformer. In addition there are several areas where 240 breaker with a neutral is feed to an outlet providing both 240 and 120 for instance your electric range, electric dryer. – spicetraders.

2. You do not tamper with the motor. You buy a step-down transformer rated for the current the motor needs. Get the voltage and current ratings of the motor, then just search the web for 'step-down' transformers that match your 230 to 240 vac line voltage on the primary side, and 120vac on the secondary side. The transformer needs to handle the
P=E^2/R, so the power generated in each lamp, which in an incandescent lamp. is used to cause the filament to glow, will be, relative to the power. generated when connected to 240 volts, 110^2/240^2 or 12100/57600 which is. approx 0.21. So your two lamps connected in parallel to 110 volts will. Changing Light Fixture Voltage. Application: Lighting Fixture Wiring and Modifications. Skill Level: Beginner to Intermediate – Best if wired by a Licensed Electrical Contractor. Tools Required: Basic Electricians Pouch Hand Tools, a non-aluminum ladder and Voltage Tester. Estimated Time: Depends on personal level experience, ability to workIf you need 240v then a 208-120/240v 1ph3w transformer would have to be considered or a buck/boost transformer which would bump the 208v to 240v. I may also suggest 240/120v 3ph/4w which would include a 240v delta with a 120/240v 1ph3w lighting tap but the lighting tap load would be limited if this were to be a single 3ph transformer.
