120V / 240V Split Phase Inverter Chargers
120/240 Vac split phase is a type of single phase three-wire mid-point neutral power distribution system commonly found in America with a standard phase-neutral voltage of 120 Vac for residential and light commercial applications. The phase to phase( Live to Live) voltage is 240Vac for heavy industrial loads such as compressors, fridge and pumps. Because of the 120-0-120 voltage configuration, it is also sometimes referred to as dual phase ,2 phase / two-phase or even mistakenly, single phase 220Vac.
These low frequency split phase inverters take 240v input from shore power or generator for charging and output 120/240 vac power, they produce 2 legs of 120v hot lines which can be hooked to the 220V main power distribution panel in your home or mobile business vehicle.
There are two 120v hot lines, one neutral and one ground.
The voltage between L1 and L2 is 240 Vac, between either one hot line and neutral is 120V. The 240V is made by the two hot lines cycling 180 degrees out of phase with each other.
This power system can drive either 120V or 240V equipments.The 120V are perfect for home and small scale commercial or mobile applications.
Our popular pure sine wave split phase inverter chargers are:
We also have specialized 120V in 240V out 4KW 12Vdc inverter charger that allows you to power both 120V and 240V loads from single phase 120V input. This model aims to boost / step up shore power from 120Vac to 240V for larger loads such as deep well pump or other dedicated high power 240VAC loads.
These split phase inverter models are a combination of 120 240V inverter, smart battery charger and transfer switch, and can be easily integrated into your current house wiring.
With the seamless transition transfer switch, the 2 phase inverters are virtually a line interactive UPS ( Uninterruptible Power Supply ) for emergency situations and natural disasters.
In North American household , the neutral is always bonded to earth ground in electrical panel. DON’T connect the AC input neutral to inverter ground. The AC input N is not required in wiring. The output Neutral of the inverter is floating, and the inverter has an internal relay that will automatically bond the neutral with ground in battery mode.
