although the product is of good quality and leaves now wish open with respect of useful and required features the product is not very useful in countries with 230/400 V grid. The inverter only can be operated in single phase 230V mode which is not useful for 7,5 kW drives. Connected to 3 phase 400 V the capacitors explode. Also 3 phase 230 V inductance motors are not available in Europe. Vevor supoort and reaction to my respective complaint was very professional, fast and satisfactory.
