2.2 kW VFD: single-phase 220 V or three-phase 380 V, where we start
This is the most popular size in our warehouse. Typical customer: a private craftsman with a small woodworking machine or a farmer with a borehole pump. For a 220 V household network we ship single-phase models. Sales leader over 12 months: Veichi AC10-T/S2-2R2G-B-VC (14 units sold), 1ph 220 V input, 3ph 220 V output. We ask one thing first. What motor do you have, 220 V or 380 V? Because a single-phase VFD will not start a three-phase 380 V motor.
For three-phase sites (380 V) the bestsellers are different. Veichi AC310-T3-2R2G-B (13 units). Next to it Veichi AC10-T3-2R2G-B (10 units). AC310 is a vector drive with built-in PID. We put it on pumps or fans where pressure or temperature must be held. AC10 is simpler, scalar, used for conveyors or machine tools. Price difference is about 25%.
What we ask before ordering: motor current, not just kW
A 2.2 kW motor from different manufacturers can draw from 5 to 10 A (Soviet AИР vs. modern import). Customers confuse this more often than single-phase vs. three-phase. We size the VFD with a 10-15% current headroom over the motor. If your start is heavy (crusher, screw conveyor, mixer with product inside), we move you up to the next size 3 kW. From experience, half of 2.2 kW returns are exactly this case. Customers took 1:1 ratio, the motor tripped on overload at start-up.
One note on the budget alternatives. INVT GD20-2R2G-4, like Delta VFD022E43A, is only available in 380 V three-phase. Single-phase GD20 at 2.2 kW is almost never in our warehouse stock. Ask us before ordering, sometimes we bring it in within 7-10 days. Warranty is standard. Veichi 24 months. INVT 24 months. Delta 18 months. Mitsubishi 18 months. Delivery from our Kyiv warehouse takes 1-3 days.
| Model | Series | Supply | Application |
|---|---|---|---|

Common Mistakes When Selecting a 2.2 kW VFD
- Selecting by power instead of current. a 2.2 kW motor from different manufacturers may draw 5 to 10A. Always match the VFD to the motor rated current.
- Single-phase VFD on a three-phase supply. single-phase models (220V input) do not work with 380V. Check the supply type.
- No headroom for heavy-duty starts. for conveyors, crushers, and high-inertia loads, choose one size up (3 kW).
- Scalar mode for precision mechanisms. for machines requiring speed accuracy, choose a vector VFD, not scalar.
When You Need Power Headroom
| Mechanism | Recommended VFD Power | Reason |
|---|---|---|
| Pump, fan | 2.2 kW (1:1) | Easy start, constant load |
| Unloaded conveyor | 2.2 kW (1:1) | Standard starting torque |
| Loaded conveyor | 3 kW (+30%) | Increased starting torque |
| Crusher, mixer | 3 kW to 5.5 kW | Heavy start, load inertia |
| Machine with reverse | 3 kW (+30%) | Frequent braking and reverse |
