Paul this is all good news. ?Glad to hear. ?I really can¡¯t say enough about PP post sales support, and I believe them when they mention their swap policy. ?Have a look at my post from 13 years ago about their service:?

Hi all,?
I just got my 7.5HP simple installed and my machines are running so figured I should report back. The real test will be in use but here is my preliminary update.?
First off, my main issue with Phase Perfect was the inconsistent and misleading information I got from their sales team. Primarily, the claim that the 7.5HP was discontinued and that the software on the Simple units could not handle two motor startups. When questioned, I received shallow and incomplete justifications. I hate to be that guy, but a simple voicemail to a higher-up changed their recommendations. In general, the tech department was much more helpful and clear about the capabilities of the unit.?
The tech said that the Simple unit really just has less options built in (such as capacity for regenerative loads and voltage doubling) but it is not less ¡°robust¡± in it¡¯s ability to produce three phase power. It does have a cooling fan and I¡¯ve found it has no problem starting multiple motors at once. The noise is minimal. I measured it at 42 db, a vast improvement from my rotary.?
The tech also reassured me that they have a very generous swap out policy with all their customers. If the unit is installed but is running into initial issues during use (such as not handling multiple loads or startups during actual use) they will take back the used unit and send a larger or different model for the price difference. You, of course, have to fall within a reasonable time window of use and work with the tech to troubleshoot the unit that is installed.?
I got a 27A unit to run a 14.5A machine. I understand the argument for going bigger for the future, but my shop is small for the equipment we have and it is not sensible to operate more than one machine at a time. So, I just could not justify the extra $1,700 for the unit plus material cost to run a new 80A circuit.?
Another thing to note: although there is not an option for a shut off switch on the Simple model, the same circuitry exists as on the Enterprise. A digital jumper wire is simply pulled and wired with a 5v switch.
So far I¡¯m very happy with the Simple unit and the Phase Systems tech department.?
Thank you for all your input and advice.?
Cheers,
Paul

Hi Aaron,
?
This picture of simple model shows what appears to be a fan at the bottom. It would be nice if an owner of simple model could chime in with details.

The manual says ¡°Hard starting loads such as fans, conveyors, and pumps may cause the PTS to briefly reduce the voltage on the generated leg during motor start¡±. Based upon this, 16¡¯ planning head and shaper with heavy tooling should be fine. Overcurrent/Motor Starting graph below shows that 7.5HP model can deliver over 50A for 10 S. I think this is more than sufficient if the specification actually represents true performance.

The missing capacitors you identified might belong to the line filter per the manual below. So one could expect more electrical noise compared to the enterprise model.

As I mentioned to the OP, running a device close to it¡¯s rating does have an impact on life. Someone also mentioned that there might be more equipment in future so a bigger model may be good investment.

Looking at the manuals, the "Simple" model is significantly smaller in size compared to the "Enterprise" model:
7HP Simple: 17 9/16¡± x 12 5/16¡± x 6 5/16¡±
7HP Enterprise: ?25 7/16¡± x 17 1/4" x 7 3/8¡±
Looking at an internal diagram where Enterprise is on top and Simple on bottom, it appears that we have capacitors in the main AC-to-DC power supply on the left.? However, only the Enterprise has capacitors on the upper right for the board that drives the third leg.? The Simple model also does not appear to have any forced air cooling inside the unit.?? On the Enterprise, the big rectangle section in the middle is a forced air cooling area that aids with the other case fans.? I believe the Simple model just does not have room inside the case to put output run capacitors or cooling.
This could indicate that the "Simple" model does not have enough grunt to drive multiple motors or start a secondary motor while driving the first motor.?? In any event, I suspect the Simple model will not perform as well as Enterprise.
