When you're choosing a variable frequency drive for a 7.5KW (10HP) motor and you're limited to 220V single-phase input, a 1-to-3 phase VFD is the piece of motor controls that gets you to three-phase output. A VFD lets you match motor speed to the load, which is why these drives show up in fan, pump, and compressor work. These two listings compete for the same installation: both are new, both accept 1 or 3-phase input and output 3-phase, both use SPWM control, and both are listed from the US. That leaves a $0.47 price spread plus a few spec differences as the entire decision.
Quick verdict
The Findmall 7.5KW VFD is the lower-priced listing at USD 118.92, while the Marddpair 7.5KW VFD is listed at USD 119.39. Both share the same control mode, input phase options, 48-63Hz input frequency, and New condition. With the price gap this small, the spec sheet is the real deciding factor, and the comparison table below puts it side by side.

Where each product wins
The Findmall listing headlines a multiplex terminal design within its description of constant torque loads and variable torque loads. The description calls out hard-starting air compressors and HVAC units on the constant side, and pumps and fans on the variable side. That makes it the listing with the broadest application story.
The Marddpair listing wins on spec headroom and documentation. The description names every connection point: R/S/T for AC input, U/V/W for motor output, P+/PR for a braking resistor, and E for ground, and it spells out the setup methods in detail. For buyers who want to map out the wiring before committing, that level of detail is a real asset.
Product notes
Findmall 7.5KW VFD Inverter
The Findmall is the pick if you want a straightforward 7.5KW drive with wiring flexibility. The description calls out constant torque loads such as hard-starting air compressors and HVAC units, plus variable torque loads such as pumps and fans, which covers the most common VFD use cases. It also describes two sets of terminal functions, with digital and analog control terminals for versatile wiring. The concrete limitation is the 20A per-phase ceiling, which is the more conservative figure of the two listings. If you're confident your motor stays within that envelope, the lower listed price and the flexible terminal block make this the simpler buy. It's the listing that gets the job done without extra reading.
Marddpair 7.5KW VFD Inverter
The Marddpair suits buyers who want more detail before they wire anything. The description walks through the R/S/T input terminals, U/V/W output, P+/PR braking resistor connection, and E ground terminal, and it spells out the setup methods: direct panel buttons, external 0-5V or 0-10V voltage signals, and 4-20mA or 0-20mA current signals. That makes it the easier unit to plan around if you're using external controls. The concrete limitation is the higher listed price of the two, so it's the pick when you're willing to pay a little more for the additional spec detail and the stronger documented setup. The extra documentation is the trade-up.
Final choice by use case
If your priority is the lower listed price, the Findmall 7.5KW VFD is the pick. If your priority is a more detailed setup guide and more spec headroom, the Marddpair 7.5KW VFD is the pick. For most installations, the two listings are close enough that the choice comes down to one question: do you want the flexible terminal story and the lower price, or the stronger spec sheet and the clearer wiring guide?
