USA/Canada single phase 240v power source consists of 4 lines, named L1, L2, N, G
L1-N = 120V, L2-N = 120V, L1-L2 = 240V
Even though GoHz single phase frequency converter can be made for 120v input, it will require additional auto-transformer inside the frequency converter to boost the voltage from 120v to 240v which will increase the weight of the converter along with the total costs.

Generally, GoH ...

Three phase asynchronous AC motor is widely used in industrial and agricultural production due to its simple structure, low cost, easy maintenance and easy operation. 3-phase AC motor uses 3 phase power supply (3 ph 220v, 380v, 400v, 415v, 480v etc.), but in some actual applications, we have single phase power supplies only (1 ph 110v, 220v, 230v, 240v etc.), especially in household appliances. In the case to run the three phase machines on single phase power supplies, there are 3 ways to do ...

While switch to "self-control", all of the output parameters are controlled by the frequency converter, at the moment, all external controls are inoperative;
Frequency converter PLC control switching
While switch to "external PLC control", the keyboard of the frequency converter is inoperative, all control commands are transmitted by external PLC, refer to following instru ...

Few days ago, GoHz made a 24V 2000W power inverter in home, sharing some design schematics and circuit diagrams.

First step: For safety, please cut off the frequency converter power before doing it.
Open the left and right side covers of the converter, as show in following figures:

Frequency converter covers

Second step: Power on the frequency converter and switch on power, push the green start button, check the LED indicators will be lighting or ...
