How do I choose the right power capacity (kVA)?

The required capacity depends on the rated power, operating current, starting current, and load characteristics of your equipment. Please provide the equipment specifications so we can recommend a suitable model.

Can it supply power to industrial machinery and motors?

Yes, subject to compatibility with the equipment's voltage, frequency, phase, and load requirements. For motors with high starting currents, the starting and overload requirements must be evaluated before selection.
