This 2.2KW 3 phase inverter is very smart. it has lots of differents mode of operation. I had asked the seller the manual before ordering to be sure and what i received exactly conforms to the manual. I have quickly tested basic operation with an old motor that did not run since at least 40 years !!! all is OK. The old motor is still alive ! I was surprised to observe the motor running down to 0.6 Hz !!! very slow, but still plenty of torque. Only negative point: the cooling fan is noisy and runs all the time. It should rather be controlled by a temperature switch. I recommend this range of products.
Communication with the seller is very difficult, you have to wait 2-3 days for an answer (at best). Product never sent. The seller gave a fake tracking number. I wasted my time, my money for nothing. Buy this product from other store, you will save your time and money.
