1.5 kW VFD: single-phase 220 V or three-phase 380 V, where we start
1.5 kW is one of our most popular sizes for small installations. Typical customer this year: a private craftsman with a small machine tool, a farmer with a borehole pump, a co-op with a greenhouse fan. The first thing we ask in the shop: what supply do you have on site. For a domestic single-phase 220 V network we take single-phase models (1ph 220 V input, 3ph 220 V output) — there are plenty of these at 1.5 kW. For an industrial 380 V motor we take three-phase. A single-phase drive will not start a three-phase 380 V motor, so this is question number one.
The current rule of thumb is simple. A 1.5 kW motor on 380 V draws about 3.5-3.7 A, so take a drive rated from 3.7 A output. A 1.5 kW motor on 220 V pulls 7-7.5 A, so the drive needs 7 A output and up. If the motor nameplate is closer to 4 A (380 V), some headroom helps — look at 2.2 kW.
The model we fit in 9 out of 10 cases
For 1.5 kW the budget Chinese brands move fastest, because overpaying for premium European on this rating for a pump or a machine tool makes no sense. For three-phase 380 V we take Veichi AC01-T3-1R5G-B (3.7 A, compact, V/f control) or INVT GD10-1R5G-4-B. For a single-phase 220 V network — Veichi AC01-S2-1R5G-B (1ph 220 V input, 3ph 220 V output, 7 A) or INVT GD20-1R5G-S2. When the customer asks for a European brand for the same job, we fit Schneider ATV310HU15N4E (Altivar 310, 4.1 A, 3ph 380 V).
What else we ask before ordering. First: load type. Pump or fan — easy start, the basic V/f series is enough. Conveyor, mixer, machine tool with frequent starts — allow current headroom. Second: do you need Modbus for SCADA. Veichi AC01 and INVT GD10 ship with an RS-485 port. 24-month warranty on all brands above, delivery from the Kyiv warehouse in 1-3 days.
