Just be mindful of the operating temperature.

I’ve been using this 5.5 kW inverter on a 3-phase motor for a small milling setup. It’s great that it supports different input voltages, which gave me flexibility during installation. That said, the unit runs a bit warm in a tight cabinet, so make sure you’ve got decent airflow around it.
