F: Wie groß ist ein Wechselrichter zum Betrieb einer 0,75-PS-Pumpe?

A. It is 0.75HP, the same power with 0.75HP pump. Choose a 1 HP (≈0.75 kW) VFD or inverter to run a0.75 HP submersible pump. For 230 V single-phase, select 1–1.5 kVA continuous rating with 2.5–3 kW surge. A VFD provides soft-start and reduces starting current. For three-phase or BLDC pumps, match inverter kW to motor rating and include proper protection devices.
