When a workshop only has single-phase 220V power but the motor needs three-phase, a 7.5KW variable frequency drive closes that gap. The tricky part is choosing between two 10HP 220V inverters that look almost identical on paper. Both are listed as new, both use SPWM control, both accept 1 or 3 phase input, and their ratings line up closely. The ALL-CARB Single To 3 Phase model and the findmall 1 To 3 Phase model are listed less than a dollar apart. The decision should come from how each drive is described, not the cost.
Quick verdict
Pick the ALL-CARB drive when your project needs a much wider speed range. Pick the findmall drive when you want load-specific guidance and richer control terminals. For a pump, fan, air compressor, or HVAC setup, the findmall listing spells out the loads it can handle. For a speed-critical motor application, the ALL-CARB listing gives you frequency headroom.
Price and spec comparison
| Listing | Listed Price | Price Bar | Output Frequency | What Stands Out |
|---|---|---|---|---|
| Single To 3 Phase 7.5KW 10HP 220V Variable Frequency Drive Inverter CNC VFD VSD | USD 119.15 | 0-3200 Hz | 208-240VAC output at 220V input | |
| 1 To 3 Phase 7.5KW 10HP 220V CNC Variable Frequency Drive Inverter VFD VSD | USD 119.34 | 0-400 Hz (0-50/60 Hz standard) | Load-type guidance for pumps, fans, air compressors, HVAC |
Where each drive stands out
ALL-CARB - Best for speed-critical setups. This is the more speed-oriented listing in the pair. If your project depends on running a motor across a broad speed envelope, this one gives you the room to do it.
findmall - Best for application clarity. This listing tells you which real-world loads it suits, including hardware like air compressors and HVAC units. If you want a drive with the load matching spelled out, this is the one.
Product notes
Single To 3 Phase 7.5KW 10HP 220V Variable Frequency Drive Inverter CNC VFD VSD

The ALL-CARB Single To 3 Phase 7.5KW 10HP 220V Variable Frequency Drive Inverter CNC VFD VSD is listed at USD 119.15. Its most useful differentiator is the output frequency range, which the listing states as 0-3200 Hz. That is a wide speed envelope for a 7.5KW drive and makes it the better recommendation when your motor needs to run far above standard 50/60 Hz operation. It shares the same 20A per-phase maximum as the findmall model, and it also lists 208-240VAC output with 220V input. The tradeoff is that its description focuses on frequency and output voltage rather than load types or terminal layout, so it provides less application guidance.
1 To 3 Phase 7.5KW 10HP 220V CNC Variable Frequency Drive Inverter VFD VSD

The findmall 1 To 3 Phase 7.5KW 10HP 220V CNC Variable Frequency Drive Inverter VFD VSD comes in at USD 119.34 and matches the ALL-CARB unit on core specs: new condition, SPWM control, 48-63 Hz input, and 20A maximum per phase. Where it separates itself is application guidance. The description explicitly covers constant torque loads such as hard-starting air compressors and HVAC units, variable torque loads such as pumps and fans, and notes that it can serve as a motor speed control and phase converter. It also calls out two sets of terminal functions and rich digital and analog control terminals. The tradeoff is frequency ceiling: the listing shows 0-50/60 Hz standard and a 0-400 Hz maximum, far below the 3200 Hz listed for the competing drive. If you need detailed load guidance and terminal flexibility, this is the one.
Final choice by use case
Choose the ALL-CARB Single To 3 Phase 7.5KW 10HP 220V Variable Frequency Drive Inverter CNC VFD VSD when your priority is maximum frequency headroom. Choose the findmall 1 To 3 Phase 7.5KW 10HP 220V CNC Variable Frequency Drive Inverter VFD VSD when you want a drive with clearly described load types and expanded terminal options.
